Downlight - Are you interested in downlights, recessed wall lights or LED spotlights for installation in a ceiling? What options do you have for setting accents in your room? Find out here what the differences are and what you should look out for when buying. In the eibabo technology store you can get downlights in different shapes and sizes, as complete recessed lights or as individual chassis. Some bulbs are included in the scope of delivery.What are downlights?Downlights are subtle lights that can have a big impact. They are ideal for all rooms in which accentuated or area lighting is required without the luminaire itself being the focus. Downlights are installed in the ceiling and create a stylish and effective ambience. The difference to classic recessed spotlights lies in the relatively wide beam angle.Where can you use downlights and recessed spotlights?Downlights or recessed spotlights are available in different versions. These can be perfectly adapted to the respective environment. There are models with a round or square frame, different light colors and different light intensities. So you can find exactly the lighting that suits your space and your needs. Use downlights for general room lighting. For example, they can be installed in the kitchen above the stove or worktop. Downlights are also a good choice in hallways and stairwells, as they ensure optimal illumination of the route. In rooms with high ceilings, such as offices or hotels, downlights ensure pleasant and even illumination without glare. Downlights are also ideal in the area above the washbasin with mirror. TIP:If you want to illuminate an area, you prefer downlights. If you want to set accents, use recessed spotlights. Recessed spotlights are often integrated into pieces of furniture and produce a narrow cone of light with a sharper contrast between light and shadow. Recessed spotlights are ideal for illuminating pictures in galleries or for emphasizing dark areas. Recessed spotlights are easy to install and in many cases replace conventional pendant lights. Due to their compact size and the unobtrusive design, downlights and recessed spotlights adapt perfectly to the environment and turn every room into a stylish place.What should be considered before buying downlights and recessed spotlights?Downlights and recessed spotlights are permanently attached to the building. These cannot be easily removed like a floor lamp or desk lamp. So plan carefully. Subsequent changes can be complex.Mounting, installation depth and fire protectionWith flush mounting, the light is built into the wall or ceiling and only the cover frame remains visible. Individual lights and series built-in lights can be used. The installation depth varies depending on the design. There are flat models that are only 1 to 2 cm deep and deeper models that are 6 cm or more. Pay attention to the heat development. Classic lamps get hot. Good rear ventilation is used for fire protection. Heat development is significantly lower with LED lights. locationIf you want to install recessed lights in the bathroom, sauna or laundry room, they should be suitable for use in humid environments. Please refer to the product description to see whether your desired model meets the necessary requirements. Pay particular attention to the IP protection class. Image: EVN PC650N91602 P-LED recessed ceiling lightpower supplyIn the case of permanently installed downlights, power is usually supplied via the house installation. Would you like to opt for a high-voltage system or a low-voltage system? Depending on this, external or integrated power supplies are required. Number of lights and positioningFirst of all, you should think about which areas of the room you want to illuminate. The positioning of the recessed spotlights depends on the existing incidence of light through windows and other light sources. The number of lights is determined by the type and size of the room. As a rule, you install at least 2 to 3 recessed spotlights per square meter of room area. Make sure that the recessed spotlights and ceiling spotlights are not too close together. Otherwise the light would not be evenly distributed and shadows may form. The beam angle is also important for ceiling spotlights, as this determines how the light is distributed in the room. A narrow angle provides direct lighting, while a wide angle spreads the light more diffusely. Depending on the atmosphere you want, you should choose the right beam angle. Different light needsSome conventional lamps and LED recessed spotlights are dimmable. These offer the advantage that you can adjust the brightness depending on the situation. The brightness of the lighting should be selected so that it is comfortable for the desired atmosphere. Make sure that there are minimum legal requirements when it comes to lighting workplaces, for example. The color of the lighting should also be chosen carefully. Lighter colors like white and blue can brighten up a room and make it look friendlier or create a cool, fresh atmosphere. Warm colors such as yellow or orange are ideal for creating a cozy and cozy atmosphere. Experiment with different colors to find the right lighting for your space. flexibilityFixed lights are less flexible than other light sources. But here, too, you have the option of varying the direction of the beam angle using swiveling inserts. What advantages do LED downlights and LED recessed spotlights offer?You can install LED recessed spotlights and LED downlights almost anywhere. These are compact and provide a pleasant and stylish atmosphere in every home as general room lighting or as accent lighting. Many LED recessed spotlights are dimmable, so you can adjust the light intensity to your liking. There are now hardly any limits when it comes to the color of light. The biggest advantage of LED technology is its energy efficiency. Compared to conventional light bulbs, LEDs consume very little energy and save money. High-quality LEDs have a long service life and do not need to be replaced as often.Please noteThe illuminant is already integrated in many LED recessed spotlights. If you want to influence the brightness and light color individually, please choose a model with a changeable lamp.Recessed LED lights, where you can change the bulb, usually have a GU10 socket. When buying the lamp, make sure it has a G10 base and that the specified maximum power is observed.Should I opt for low-voltage technology for downlights and recessed spotlights?Is high-voltage technology dangerous and is low-voltage technology better? Whether LED or conventional light sources, there is the right technology for every taste when it comes to downlights and recessed spotlights. Both high-voltage technology and low-voltage technology have advantages and disadvantages. Incidentally, you have not only been faced with this choice since LEDs came into existence. Even with the halogen lamps you could choose between 230V and 12V. What is high voltage?High voltage is not high voltage. According to the general definition, high voltage begins at 1,000 volts. Low-voltage recessed spotlights are mostly operated with a voltage of 12 volts, some LEDs work with an operating voltage of 24V. With regard to the actual light output, there are no significant differences.high voltage:no extra transformer is required, LEDs have an integrated power supplychanging between LED and conventional is easyhigher power loss and more waste heat shortens the service life of the lampsthe safety requirements are higher (fire protection, installation) low voltage:LEDs have less power loss and higher efficiencythere is less waste heat12V low voltage is less dangerous for wet rooms and outdoor facilitiesa suitable power supply unit is requiredhigher planning effort for more complex installations Which of the two technologies you choose is a question of personal taste, the location and the existing technical requirements.  Catalogue content:In this eibabo® catalogue Luminaires > Downlight/spot/floodlight you will find items from the following product groups:Item overview:A surface lightAccent lightingArea lightingBuild-up potCarrying caseColor changeCompact spotlightDepartment store lightEntrance lightHeadlight bulbInfrared sensorInterior lampInterior lightLightstreamLow-voltage spotlightMounted spotlightOutdoor lightsOutdoor spotlightPatio lightPower Rail SpotlightRecessed ceiling spotlightSpotlightSpotlightHeadlampSpotlightsHeadlightsFloodlightSquare lightStarry skyToledoFlatWallwasherfrom the following manufacturers:Manufacturer overview catalogue Downlight:AbalightArcliteAura LightBachmannBarthelmeBaulmannBEGA GantenbrinkBrilonerBrumbergBöhmerEgloESYLUXEVNFischer & HonselHeraIDViiMIlluminaKonstsmideLEDVANCELTSOligoOpple LightingPaulmannPerformance in LightPhilips LichtRegioluxRidi-LeuchtenRZBSchmitz-LeuchtenSignify PLSSitecoSLVSun CracksTriluxWitte + SutorZumtobelZumtobel Group
Tactile sensor - Smart, individual, simple, extravagant, futuristic - touch sensors, also known as KNX buttons, like to attract admiring glances and their modern design alone suggests to every user that this is more than a conventional light switch. Rockers, glowing LEDs, small symbols or even LCD displays give an idea of the numerous functions hidden behind many an installation. In addition, there is often a very noble selection of materials such as high-quality metal, acrylic or glass, which always exudes a touch of extravagance. But why are multifunctional touch sensors needed and how do you use their potential optimally? We give you a brief insight here.The basics in a nutshellTouch sensors are multifunctional control elements for the smart home.The design and function selection is huge, from a single button to a control center with 12 or more buttons, everything is possible.You can use it to control, for example, the light, its dimming, blinds, heating, entertainment center, door opener and all other devices in your home network.The button functions can be assigned individually and can be easily reprogrammed if necessary.Integrated LEDs or other displays often show the respective operating status or provide information about errors.   What is a touch sensor or a KNX button?You can operate the end devices integrated in your smart home network with a touch sensor or a KNX button. This can be blinds that you can raise and lower - light that you dim - the heating that you regulate or completely individual, user-defined scenarios. Depending on the model, operation is optically individual. In general, it is operated using a different number of buttons or rocker switches and/or even displays.The different types of KNX buttonsUsing a KNX universal button interface, you can basically turn any conventional button into a KNX button. These interfaces are installed in a deep device box behind the standard button and thus take on the task of the binary input, which converts the classic switching processes into KNX signals.Which doses are suitable?To do this, use a branch switch box with 4 screw domes or a deep switch box or an electronics box. Use our eibabo® search to quickly find the right item.This solution is particularly suitable for the standard application 'basic lighting' per room (see: 'What are standard applications?') or for the modernization of existing installations as well as for inexpensive and functionally manageable system extensions.'Real' KNX tactile sensors are much more complex and range up to control elements with elegant touch displays. Temperature sensors, LED displays and background lighting are often already combined in one device. In contrast to the simple interface variant, there is often the option of providing each key with additional functions, which are then triggered, for example, by a long press, double-click or even triple-click. TIP:We recommend planning well in advance so that you can later fit all the functions you need into your keypad. While some KNX push-button sensors require a separate bus coupler to which they are plugged, the bus coupler is already integrated in others. The eibabo® technology store also has both complete KNX pushbuttons and pushbutton sensor modules. The latter is 'only' about the technology and you can choose a matching design cover yourself. The possibilities are diverse - you can choose exactly what suits your project.The advantages and disadvantages of tactile sensorsThe central control of a large number of actions on different end devices is certainly the greatest advantage. The plus in comfort is combined with the flexible options for changing and expanding a well-planned setup. The disadvantage is certainly the slightly higher acquisition costs of a smart home solution compared to a conventional electrical installation. In the case of units with many keys and each assignment with different control variables (print, double-click), the overview of all the functions and their control can easily be lost.Unusual application examples in everyday lifeWe have already mentioned a few classic use cases. In the course of our more than 25 years of work, we have also been able to implement 'very special' projects. It starts with the smart opening and locking of the cat flap in the basement, continues with the choreographed lighting of exterior facades and doesn't end with the automatic pool cover, the fully automated aquarium or the heated driveway in winter.  You want to know more? We answer frequently asked questions.Nobody knows everything and sometimes there are small ambiguities that prevent us from correctly grasping connections or from deciding on one or the other product. You may also find an answer to your question in the following topics.How are the KNX devices programmed?Many interested parties are quickly startled by the term 'programming', but it's not that difficult at all, because it's not actually programmed with the 'ETS', but assignments and parameterizations are carried out.What does ETS mean for KNX?The term ETS (Engineering Tool Software) means that it is programming software for commissioning the KNX devices. The tool is more of a software for parameterization and basically also suitable for laypersons with an interest in the logic of the KNX.No programming knowledge or programming language is required. If you are interested in the rather simple logical connections of the KNX bus, you are in a position to create a project. Of course, more complex projects require a certain amount of experience. We always recommend having the basic project created by an experienced system integrator. This allows you to easily change important parameters yourself later on, since many things change in the life cycle.Which touch sensor or KNX button should I buy?Well, we can't give a general answer to this question, but we can perhaps provide some impetus for decision-making. KNX push button sensors are available in a variety of designs. The manufacturers offer solutions for every taste. However, you should not only be guided by the optics. In addition to the optics, eibabo® also recommends checking the applications (parameters and functions) provided by the manufacturer for the ETS (Engineering Tool Software). Significant deficits can open up here in the course of a project if the beautiful button were not able to control the necessary actions correctly. Plan exactly which requirements you place on the respective push button sensor and then select a suitable model accordingly. NOTE:ETS is standardized software for commissioning the KNX devices and can be obtained from www.knx.org. With regard to the design, you should also rely on optics that have a positive effect in the long term and not follow every short-term trend, only to realize a few years later that the brightly colored displays and the LEDs for various status messages on the buttons in the wall were a bit too much of a good thing. It makes sense to ensure that displays can be dimmed or configured in different brightness levels and status LEDs can be configured and switched off. A timeless surface design, for example, has simple elegance, looks classy, is durable and has no playful rockers that could quickly gather dust.How do I recognize whether a touch sensor already has a bus connection?Some touch sensors already have a bus connection. If you're not sure, a look at the back will clarify.Image: KNX push button sensor - Jung 4047TSMA touch sensor is equipped with a bus coupling if it has a black and red (or gray and red) terminal for the bus on its back. This 4-wire terminal with plug-in terminal connection serves as a distributor for up to four KNX lines.How do I keep track of the individual functions of complex touch sensors?We would like to encourage you to think: Imagine you come into a room and have to press the small second rocker from the top left on an 8-way pushbutton sensor every day to switch on the basic lighting. It can quickly happen that you accidentally set the pressure point on the adjacent rocker and unfortunately operate the blinds at 11:00 p.m. Not to mention how a guest or child is supposed to cope with it.So it can indeed be a bit difficult to always steer correctly. But: The advantages of the KNX lie in the intelligence of the system, which is implemented by the system integrator based on their experience and your functional requirements. For this reason, you should arrange functions logically or thematically and, if necessary, group them on easy-to-use buttons. If necessary, it is advisable to divide standard applications and detailed circuits into different buttons at different mounting heights.What are default applications? What is the best way to implement this into the system?The first switch box is usually placed on the 1.05m upper edge of the finished floor. At this point you should mount a conventional double button and connect it twice to the bus via a very inexpensive KNX button interface. Of course, you can also mount 2 or 3 double buttons and integrate a 4-way or 6-way KNX button interface. A deep switch box or electronics box is installed as a flush-mounted box in order to be able to place the small button interface behind the double button.Here you save!Combine a KNX button interface with a conventional double button.With the conventional double button, you have more choice in the design of the switch range and, in the event of defects or design changes, you can obtain a lifetime replacement without having to reprogram. You can assign the most important and most frequently used basic lighting to this button or parameterize the button or the button interface with light scene recall. A beautiful flat switch is also very easy to use for guests and children.What is meant by detailed switching on the KNX button?You should mount detailed circuits of the certainly many functions in a room on the 1.60m upper edge of the finished floor and call them up from a room controller or multiple push-button sensor with an optionally integrated room temperature controller (see also our multiple control unit catalogue). A room temperature controller already requires this mounting height for optimal control. At this user-friendly height, you can then carry out all additional controls for additional lighting, blinds, roller shutters, entertainment, etc.Touch sensors wear out very quickly! Is that correct?Like all other technical components that are used more or less every day, tactile sensors and control points in general are subject to a certain amount of wear and tear. However, this is no different than with conventional buttons or switches. It is possible that individual parts that have been in use for a decade are then worn out.Does it make sense to control the heating using touch sensors?Definitely, as a rule, individual room heating controls are also required for KNX installations. In terms of value for money, the combined buttons with room temperature controllers are the best choice, also in terms of user-friendliness.Which manufacturer offers the most beautiful and best KNX buttons?Beauty is in the eye of the beholder, we won't take a position on that. In terms of quality, however, all brands perform very well. There is no such thing as the 'best' touch sensor. Each manufacturer has its individual strengths in terms of applications (parameters and functions). eibabo® offers switches from all brand manufacturers (from ABB, Berker, Busch-Jaeger, Gira, Hager, Jung, MDT, Merten to Siemens). Select KNX push-button sensors in the following versions: KNX push-button sensor, KNX sensor unit, KNX wall sensor, KNX room control unit, KNX push-button sensor module, KNX push-button sensor extension module, KNX push-button 1-fold, KNX push-button 2-fold, KNX push-button 4-fold, KNX push-button 5-way, 6-way KNX button, 8-way KNX button, KNX control panel, KNX button with bus coupler, KNX button module, KNX touch sensor, KNX button sensor plus, KNX glass button.  Catalogue content:In this eibabo® catalogue Installation bus systems > Touch sensor for bus system you will find items from the following product groups:Item overview:Adapter frameBuilding controlBus couplerBus technologyButton couplerCabel CanalColor displayContactlessControl elementGlass buttonGlass sensorGroup button bus couplerLight scene touch sensorsNickel metallicOutdoor areaPendulum fanReceiving sensorRemote controlRemovable fanShutter buttonSingle rockerSplash proofTactile sensorsTemperature sensorTitle blockTouch sensorWireless pushbuttonWireless solutionfrom the following manufacturers:Manufacturer overview catalogue Tactile sensor:ABBAVM ComputersystemeBerkerbticinoBusch JaegerEatonElsnerESYLUXGiraHagerIssendorffJungLingg & JankeMaicoMDTMertenRopagSiemensTheben
Low-voltage transformer - It is often not enough to mount lightbulbs in the ceiling, in the wall, in the stairs or in the closet. Especially with built-in lights, transformers are often required, which reduce the voltage to 12 volts or another value. But why are transformers necessary at all? In this text you will learn more about low-voltage transformers, how they are used and which criteria you should consider when purchasing.What are lighting transformers?Low-voltage transformers are important operating devices for lights. These are devices for converting a certain voltage to another voltage. In many cases, the 220 volts at the input of the device is converted to 12 volts at the output of the device. On the one hand, this reduction serves to ensure safety, because a 12 volt voltage does not pose a danger to life and limb when touched. This also ensures that the lamp does not fail in the event of voltage peaks. In other words: a transformer protects against short circuits and overheating and is a device that makes it possible to switch the light on and off.Image: LEDVANCE HTL225/230-240 Halotronic transformerDo transformers affect the lifespan of the lamp?How long a lamp works depends on its quality, frequency of use and duration of use. Frequent switching cycles have an effect on the service life, especially with conventional light sources. Continuous operation of the light bulbs can also lead to wear and tear and premature failure. In principle, a transformer connected in front of it has no influence on this. However, the device 'smoothes out' fluctuations in the energy supply and can thus positively influence the service life of a classic light bulb. In this regard, it should be noted that even transformers can burn out over time. However, this happens very rarely and also depends on the quality of the device. In times when conventional light sources are increasingly being replaced by modern and long-lasting LED technology, the question of consumption and efficiency is often asked in contrast to lifespan.Is a 12 volt bulb more economical than a 220 volt bulb?It is widely believed that 12 volt incandescent lamps save electricity compared to 220 volt incandescent lamps. However, that is not true. Saving electricity depends on the power and not on the voltage.How do I find the right transformer for my lighting?Because transformers are commonly used with recessed lights, we'll stick with this type of lighting. It depends on the lamps used which transformer you need. For safety reasons, the use of low-voltage lights is strongly recommended, especially in rooms with high humidity. If you use LEDs, you need a different transformer than with classic halogen lamps. So before you choose one or the other transformer, you have to decide on a specific light source. The service life of LEDs is usually more than 50,000 hours. These are therefore much more durable than comparable halogen lamps. In addition, the heat generated by LEDs is significantly lower, which is an advantage for built-in lights without air circulation. Disadvantages of LEDs are the higher price and the special nature of the light emission. Their light is generated by a directed luminous flux, which can quickly lead to signs of fatigue. Therefore, LEDs are mainly used as accent lighting in the background (in cupboards and shelves, as an orientation light on the stairs). A lamp with halogen lamps is typically recommended for the basic lighting of a room.Basically, we distinguish between low-voltage transformers:Devices that have a winding and work by means of inductionDevices that are exclusively electronically controlled Transformers with winding are primarily used with halogen lamps. These consist of two copper windings (coils), which interact with each other through an electromagnetic field and can thus reduce the voltage. The electronic transformers reduce the mains voltage using electronic circuits. These devices are therefore the newer generation and offer the following advantages over conventional transformers:light and compacthigh degree of protection against short circuitsalmost silent operationProtection against overload and overheatingSoft start possible With these features, longevity is achieved for both the transformer and the halogen lamps. Already knewElectronic transformers have an efficiency of over 95%. Transformers with coils achieve an efficiency of around 80%. When using LEDs you need a different type of transformer. Please note that these devices are not interchangeable with the transformers for halogen lamps, even if they have the same nominal power and output voltage. In a halogen lamp, the filament serves as the light source. The lighting of an LED is based on completely different physics. Here, electric current flows through a diode and releases some of the energy in the form of light photons. This difference in the generation of light places individual demands on the respective electronic transformers, for example:Transformers for halogen lamps generate an AC voltage. This has positive and negative pulses and is not suitable for continuous operation of an LED. An LED is operated with direct current. Although many LEDs have a rectifier, the conversion can lead to increased heat generation and thus to a shorter service life.For example, in the case of transformers for halogen lamps, the average output voltage is 12 volts. In reality, however, this value is not constant and can vary up and down. These can be voltage peaks when switching or depend on the mains voltage at the input, the connected load and the ambient temperature. A halogen lamp can cope with these fluctuations without being damaged. An LED cannot do this.LEDs have significantly less power than halogen lamps. An electronic transformer for halogen lamps requires a certain base load in watts in order to function properly. If this base load is not reached, the light flickers, shines too weakly or not at all.Is it possible to dim halogen lamps and LEDs with a transformer?Regardless of whether you are using a conventional or an electronic transformer, dimming 12 volt halogen lamps is usually always possible without any problems. It is only important that the individual components are compatible with each other.TIPTypically, so-called leading edge dimmers are combined with conventional transformers, whereas trailing edge dimmers are used for electronic transformers. If you are not sure, choose a universal dimmer from our range.If you want to dim LED lamps, all interacting components must be marked accordingly. This means that both the transformer and the LEDs themselves, as well as any ballast that may be required, must be dimmable.Which low-voltage transformers does the eibabo® shop offer?At eibabo® you will find an extensive range of lights and the right low-voltage transformers for your lighting installation. In addition to dimmer transformers and DALI switching power supplies, we also carry low-voltage transformers, plug-in transformers, safety transformers, electromagnetic transformers, power supplies, ballasts and Tronic transformers.

Install. box - device install. duct - Device installation trunking is very often used where a lot of communication technology is required in a small space. The ducts themselves are wall mounted by default and include plenty of power and data cables. You can discover such installations in authorities as well as in car dealerships or supermarkets. However, the ducts are not only used to hide the cables, they are also potential connection points for power supply or network connections. The sockets, telephone and network connections required for this are installed and fastened in the ducts using the duct installation sockets. Depending on the requirements, the channels of the different manufacturers are dimensioned differently. eibabo has a range of high-quality, low-priced installation sockets for all trunking dimensions from the most common suppliers and will deliver them to your construction site quickly and safely.Catalogue content:In this eibabo® catalogue Installation ducts for wall and ceiling > Junction box for wall duct you will find items from the following product groups:Item overview:1-fold can2-fold can3-fold canAccessory mounting boxBuilt-in boxBuilt-in installation boxCEE built-in boxCEE built-in installation boxCEE installation duct boxConnector socketData socketDevice installation systemDevice socketDouble canDouble socketDuct boxDuct installationEnergy canInstallation box for device installation trunkingInstallation channelInstallation duct boxJunction boxJunction box for wall ductMounting frameSingle boxTriple canTrunking boxUniversal data socketfrom the following manufacturers:Manufacturer overview catalogue Install. box - device install. duct:KleinhuisMetzNiedaxOBOPROTEC.classRehauSchneider ElectricSpelsbergTehalitTelegärtner
Surge protector - electr. - Are you looking for a surge arrester for your electrical installation? But you are still not sure what requirements such a device has to meet? Then read on here. In order to understand why a surge arrester is useful, you must be aware of the dangers associated with voltage spikes or surges. Even if these events are rare and only last a few milliseconds, they can still result in major damage. We therefore always recommend a surge protector to prevent the loss or damage of sensitive electronic equipment. We will help you to choose the right item.What are surge arresters?Overvoltage protection devices are of great importance in electrical engineering. These are used to limit and divert overvoltages in electrical lines and sensitive devices such as computers, televisions or hi-fi systems. But how does overvoltage occur? The normal mains voltage in Germany is 230V. Overvoltages go well beyond this value and are caused, for example, by lightning strikes, short circuits, electrostatic discharges or switching operations by the network operator. The consequences of such an event depend on the magnitude of the overvoltage, the speed of the voltage pulse and its duration. Failure to set up protective measures can result in fire, explosion and personal injury.The surge arresters (Surge Protective Devices SPD) are installed in the distribution board or in the sub-distribution boards and connected between the active conductors and earth. Surge arresters are usually designed as pluggable modular devices or as devices for mounting on top-hat rails and some are equipped with a fault indicator. In this eibabo® catalogue, we present the devices that are used for overvoltage protection and are therefore part of the internal lightning protection of a building.Lightning protection and effective surge protectionIn order to be able to decide on a specific surge arrester, you should know the entire structure of an effective system for protection against lightning and surge voltage. Such a system usually consists of several parts. This can quickly get a little confusing. We give a small overview.Already knew?We distinguish between surge protection and lightning protection. Surge protection devices are designed to protect against damage caused by excessive voltage. Lightning protection systems, on the other hand, are intended to protect against damage caused by excessive currents.A few definitions of terms in advance:Lightning is high-energy and carries very high lightning currents. In the case of overvoltages, the currents and energy are small, but the charge difference between two potentials is very large. In order to counteract these dangers completely, such a system consists of three parts:the external lightning protectionthe internal lightning protectionthe overvoltage protection In this context, different categories and protection classes are often mentioned, which laypeople quickly confuse. These include:Lightning protection classes (I-IV)Buildings are divided into four lightning protection classes in order to be able to assess the risk of lightning strikes. The class in which a building is to be classified depends on its type, use and the damage to be expected. The lightning protection class determines the structure and dimensioning of the lightning protection system.Overvoltage Categories (I-IV)The four overvoltage categories describe the surge resistance of electronic devices. This specification therefore refers to end devices such as laptops (category I), toasters (category II), residual current circuit breakers (category III) or primary overcurrent protection devices (category IV). Look in the operating instructions of the respective device. The tolerability to power surges is low for electrical devices of category I and is 1500 volts. Category IV devices can handle up to 6000 volts.Surge Protection (Type 1, Type 2, Type 3)Surge protection devices (e.g. surge arresters) are divided into coarse protection, medium protection or fine protection. Which type a device is to be assigned to depends primarily on the voltage levels that it can absorb. This results in the respective area of application.Image: Dehn DG M TNS 275 DEHNguard surge arresterThe external lightning protectionExternal lightning protection consists of lightning conductors, lightning arrestors, earthing, fastenings and so on. Just this much: The external lightning protection intercepts direct lightning strikes before they hit the building. The high lightning current is discharged directly into the ground via the grounding system. In principle, there is no obligation to install external lightning protection systems in Germany unless your building:stands free on a mountainis over 20 meters highhas a combustible roof (e.g. made of thatch, straw)has public transport (theater, swimming pool) But even if your building does not meet any of these criteria, a lightning conductor is always useful, because the damage can be enormous in the event of a strike. You can find more information about external lightning protection, grounding and installation as well as purchasing here in the shop. Simply use the appropriate terms in the input field of our intelligent search.The internal lightning protectionThere is no denying that lightning and other surge voltages are dangerous. In order to protect apartments, houses, industrial plants and the devices and systems they contain, effective internal lightning protection and overvoltage protection is required. The internal lightning protection is a potential equalization in which all metal pipe installations and all cable installations in a house are connected to each other and to the main earthing bar. This prevents voltage differences, lightning flashovers in the building and the resulting danger to people and technology.The overvoltage protectionOvervoltage protection is part of the internal lightning protection. When choosing a suitable surge protector, we consider the nature of the potential interference and the type of equipment to be protected. How much energy does a possible overvoltage have? Which devices are particularly sensitive to voltage pulses due to their design? A current device for overvoltage protection has a three-stage structure and thus optimally protects buildings, systems and devices from damage. This includes, among other things, a combination of different surge arresters adapted to the respective requirements. definitionThe term 'transient' is rare in German usage. It means that something is temporary, fleeting and impermanent. There are different requirement classes for overvoltage protection devices. A distinction is made between Type 1 (general protection), Type 2 (medium protection) or Type 3 (fine protection). The standard devices represent the fine protection and protect against voltages up to a certain level, the extended devices offer additional protection against transient voltage peaks and the high protection standard also protects against impulse currents. But what does it exactly mean?Type 1 overvoltage protection is called a lightning arrester. This is suitable for deriving high lightning currents via the internal or external lightning protection system. The residual voltage is reduced to a level between 6000 volts and 1300 volts. These devices are ideally installed in front of the house installation so that the lightning current does not even get into the distribution. However, this basic protection is not yet sufficient to secure the end devices.Type 2 overvoltage protection represents medium protection and reduces the residual lightning voltages from the upstream lightning arresters to values between 2000 volts and 600 volts. These include the surge arresters offered in this category. These are installed, for example, in the sub-distributors of individual floors. Surge arresters also limit dangerous transient overvoltages caused by switching motors, transformers, circuit breakers or inductive loads. Disturbances of this type are short-lived, cause the voltage to rise very quickly, and can occur more frequently. The interference causes electronic devices to wear out faster.Type 3 overvoltage protection further reduces the remaining overvoltage and is installed as fine protection as close as possible to the end devices to be protected.What should you pay attention to when buying a surge arrester?You now know what parts make up a lightning protection system with overvoltage protection. Surge protection has been a mandatory part of an electrical system in Germany since December 2018 and must be installed in new buildings. Include this topic in the planning of your building or system and pay attention to high-quality components. Don't skimp on security. Retrofitting is also advisable for older buildings, because there are more and more devices with sensitive electronics in our households.

Surge protector - measur./control - Modern sensors, measuring devices and probes monitor and control complex and interdependent processes. Protect these operations from power surge failures. We will introduce you to different MSR surge arresters and support you in your purchase decision.   Automated processes intervene deeply in a building management system or in production processes. As a result, a very high degree of availability of the determined and transmitted measurement data and control signals is required. Surge protection devices make a significant contribution to safeguarding the function of this technology in the event of voltage peaks of all kinds. Depending on the risk potential and the level of protection required, select the surge protection devices that are right for you and combine them with other protective circuits if necessary. Image: Dehn DPA-M-CLE-RJ45B-48 surge arrester What are MSR surge arresters? MSR stands for measurement technology, control technology and regulation technology. MSR technology is used in particular within modern bus systems and telecommunications systems. Private and industrial areas of application are: air conditioning and refrigeration systems heating systems and ventilation systems the field of water technology and waste water technology the electronics sector and smart home   The MSR overvoltage protection devices are used in electrical engineering to limit and divert overvoltages in electrical lines. Particularly sensitive measuring devices and control devices can be damaged by overvoltages, incorrect measurement data can be determined and incorrect control signals can be sent. But how does the overvoltage come about? Lightning strikes, short circuits, electrostatic discharges or switching operations by the network operator generate mains voltages which are well above the normal value of 230V in Germany. The consequences of such an event depend on the level and duration of the overvoltage and the speed of the voltage pulse.   The MSR surge arresters (Surge Protective Devices SPD) are usually installed directly in front of the signal inputs of the measuring devices and control devices to be protected. In the context of a three-stage overvoltage protection, these represent the so-called fine protection (type 3). What is measurement technology, control technology and regulation technology? MSR technology records a wide variety of situations and states within automated processes. Depending on the type and area of application, individual parameters are determined using different measurement methods. Typical measured variables are temperature, pressure, speed, humidity or chemical composition. These measured variables are converted into electrical signals such as current, voltage or resistance and serve as the basis for triggering logical actions. How is an MSR surge protection constructed? A general overvoltage protection is usually structured in three stages and is part of the internal lightning protection of a building. There are different requirement classes for overvoltage protection devices. We distinguish between type 1 (rough protection), type 2 (medium protection) or type 3 (fine protection). When selecting suitable protective devices, the type of possible fault and the type of device to be protected are considered. This results in a combination of different surge arresters adapted to the respective needs, which together ensure coarse, medium and fine protection.   Type 1 coarse protection devices are used to divert high lightning currents. These reduce the residual voltage of an overvoltage to a level between 6000 volts and 1300 volts. Type 1 devices are usually switched before the house installation. This means that the high lightning current cannot even reach the house distribution system.   Type 2 devices provide medium protection. They reduce the residual lightning voltage to values between 2000 volts and 600 volts. They are installed, for example, in the sub-distributors of individual apartments or parts of buildings. Medium protection devices also limit dangerous transient overvoltages. These are caused by the switching of transformers, circuit breakers, motors or inductive loads. Already knew? Surge arresters are not disposable fuses. The devices can ensure reliable protection over a long period of time and do not need to be replaced after they have been triggered.   The Type 3 overvoltage protection further reduces the remaining overvoltage. These devices provide fine protection and protect against voltages up to a level of 1000 volts AC or 1500 volts DC. The MSR surge arresters available in this eibabo® catalog belong to this category. Are MSR Surge Arresters Really Necessary? Whether special protective measures against overvoltage are required for your MSR devices must be considered individually for each installation. Estimate the risk objectively, taking into account the probability of overvoltages and overcurrents. Base this assessment on all existing parts of your protective measures against overvoltages. Include the risk of electromagnetic phenomena such as lightning discharges or earth potential rises in your considerations. Ultimately, you should achieve reliable protection for your entire system. Please consider the organizational and financial consequences that the failure of important measurement and control devices would have for your operational processes. When should I choose an MSR surge arrester? Power connections and data lines are an integral part of our everyday lives. Stable signal transmissions are essential for smooth business operations, and not just in industrial or commercial environments. Our high-tech lifestyle also demands reliable connectivity. If you recognize yourself in any of the following questions and answers, then MSR surge arresters are for you.   Do you value security? Security devices such as alarm systems, door intercom systems, access controls and emergency call devices only offer complete protection if the power supply, the monitoring sensors and the data lines work permanently. MSR surge arresters protect those systems that ensure your protection.   You don't want to do without the amenities of modern living comfort? A lot of planning, work and money goes into modern smart home installations. The automatic control of temperatures, shutters or multimedia applications enable a comfortable living environment. With MSR surge arresters, this convenience is maintained even in the event of an overvoltage.   TIP:Investing in reliable surge protection is usually less expensive than replacing, repairing, and installing new equipment.   Would you like to secure your independence? The production of your own electricity is becoming more important every year. Modern and environmentally friendly mobility solutions and heating systems rely on electricity from your own photovoltaic system. The efficient use and storage of electricity requires complex control devices. With an MSR surge arrester, you can protect this expensive technology from surge damage. You retain your independence from energy suppliers.   Do you want to protect investments and preserve property? Real estate is an investment and provision in one. The technical equipment of a building has a significant influence on its value. By using MSR surge arresters, you not only get the building services, but also your old-age provision.   In our catalog you will always find the right surge arrester tailored to your requirements for your individual device variants. You get the best quality at low prices.

Combined arresters - eletric - Are you looking for combination devices to divert lightning currents and surge voltages for your electrical installation? But you are still not sure what requirements such a device has to meet? Learn more here. In order to be able to decide on a specific device, you must be aware of the dangers caused by lightning currents or surge voltages. Admittedly, these events are rare and often only last a few milliseconds. Nevertheless, major damage can result. We therefore always recommend appropriate protective measures to prevent damage to buildings and sensitive electronic devices. We support you in choosing the right item.Image: Dehn DSH-TNS-255 combined arresterWhat are combined arresters in power engineering?Combined arresters are of enormous importance for safety in electrical engineering. These limit lightning currents and overvoltages in electrical lines and divert them. Combined arresters are therefore used to protect sensitive devices such as computers, televisions or hi-fi systems.But what requirements do these devices combine?To understand this, we need to take a closer look at the overvoltage phenomenon. In Germany and large parts of Europe, the mains voltage is 230V. Overvoltages go well beyond this value. These are caused by switching operations by the network operator, lightning strikes, short circuits or electrostatic discharges. The resulting consequences depend on the level of the overvoltage, the duration and the speed of the voltage pulse. If suitable protective measures are missing, fires can break out or people can be injured. Since the type and extent of a fault caused by overvoltage and lightning current cannot be predicted, protective devices are constructed in three stages. We distinguish between coarse protection (type 1), medium protection (type 2) and fine protection (type 3). With each level, the overvoltage is further reduced until it can no longer pose a threat to the end devices. Combined devices for dissipating lightning current and surge voltage usually meet the requirement classes type 1 and type 2. In the following text we will explain in more detail what this means.Surge arresters and combination arresters are also referred to as Surge Protective Devices (SPD). They are usually installed in the installation distribution board or in the sub-distribution boards between the active conductors and earth. The devices are usually designed as pluggable modular devices or as devices for mounting on DIN rails. Other properties, some of which are optional, are:connectable lightning current and surge arrestershigh discharge capacity for lightning current surges up to 100 kA (10/350?s)optical status display / defect displayremote signallingshockproof and tolerable to vibrationsConnections can be labeled The construction of a lightning protection system with overvoltage protectionIn order to be able to decide on a specific combination arrester, you should know the entire structure of a lightning protection system with overvoltage protection.side noteBuildings are classified in lightning protection classes I to IV. This assesses the risk of lightning strikes. The class in which a building is to be classified depends on its type, use and the damage to be expected. The lightning protection class determines the structure and dimensioning of the lightning protection system.Whether a combination device is suitable for a building with a specific lightning protection class can usually be found in the product description. Lightning is high-energy and carries very high lightning currents. In the case of overvoltages, the currents and energy are small, but the charge difference between two potentials is very large. In order to counteract these dangers completely, such a system consists of three parts:the external lightning protectionthe internal lightning protectionthe overvoltage protection The external lightning protectionAs the name suggests, external lightning protection is protective measures outside the building. These are lightning arresters, lightning conductors, earthing, fixings and so on. The external lightning protection diverts direct lightning strikes and the associated high lightning current into the ground before they reach the building. In Germany there is no obligation to install external lightning protection systems. Exceptions are buildings which:are over 20 meters highstanding free on a hilltophave a combustible roof (e.g. thatch or thatch)are open to the public (cinema, museum) However, external lightning protection always makes sense, even if your building does not meet any of these criteria. A lightning strike can cause serious damage. Information and high-quality items for setting up reliable external lightning protection can also be found here in the shop. Use our intelligent search.The internal lightning protectionEffective internal lightning protection and overvoltage protection protects apartments, buildings, industrial plants and the devices in them. The internal lightning protection is designed as equipotential bonding. For this purpose, all metallic pipe installations and cable installations in a house are connected to each other and to the main earthing bar. This can prevent voltage differences, lightning flashovers in the building and the resulting danger to people and technology.The overvoltage protectionInternal lightning protection includes overvoltage protection. This is where the combined arresters offered in this catalog come into play. In order to be able to select a suitable device, please consider the type of possible interference as well as the type of devices to be protected. As already mentioned, the overvoltage protection has a three-stage structure. Accordingly, three requirement classes for overvoltage protection devices are also available. We distinguish between type 1 (rough protection), type 2 (medium protection) or type 3 (fine protection). Type 3 standard devices provide fine protection and protect against voltages up to a certain level. Enhanced Type 2 devices provide additional protection against transient voltage spikes. The high protection standard of type 1 also protects against impulse currents. But what exactly does that mean for the combination arresters offered here, which in many cases meet the requirements of types 1 and 2? NoticeSurge protection has been a mandatory part of an electrical system in Germany since December 2018 and must be installed in new buildings. Type 1 surge protective devices are also known as lightning arresters. These divert high lightning currents via the internal or external lightning protection of a building. The residual voltage is reduced to a level between 6000 volts and 1300 volts. However, this basic protection is not yet sufficient to protect the end devices.Type 2 surge protective devices provide medium protection. The residual lightning voltage, which is already reduced by the type 1 devices, is further reduced in this stage to values between 2000 volts and 600 volts. Type 2 devices also limit dangerous transient overvoltages. These are caused by the switching of motors, transformers, circuit breakers or inductive loads. Disturbances of this kind are short-lived. However, these occur more frequently and cause the tension to rise suddenly.Type 3 protective devices further reduce the remaining overvoltage. This fine protection is installed as close as possible to the end devices to be protected.What should you pay attention to when buying a combi arrester?You are now familiar with the structure of a lightning protection system with overvoltage protection. With the installation of combination devices, you usually cover the requirements of test classes type 1 and type 2 with just one device. When buying, pay attention to high-quality components from trusted and well-known manufacturers. We also recommend retrofitting surge protection in older buildings, because the number of devices with sensitive electronics in our households is constantly increasing. When buying, also pay attention to:mounting typeRated voltage AC/DCHighest continuous voltage for AC and DCDissipation capacity for lightning current surgesnumber of polesSuitability for buildings with a special lightning protection classProtection level (must not exceed the impulse withstand voltage of the installation and the connected equipment) Considering your electrical installation in connection with the assessment of your individual protection requirements will help you to choose the right combination arrester. TIP:With a combination device, you save money and space in the control cabinet. You get easy-to-install, comprehensive protection. At eibabo® you can get a large selection of combination arresters for electrical engineering in different designs. These include: CombiController, lightning current arresters, arresters for busbars, combined arresters for meter applications, type 1 + type 2 combined arresters. Also take a look at our extensive range of single-pole and multi-pole devices with integrated arrester back-up fuse.  Catalogue content:In this eibabo® catalogue Earthing, lightning and surge protection > Combined arrester for power supply systems you will find items from the following product groups:Item overview:Charging infrastructureCombiControllerCombined arresterCombiner boxComplete blockComplete unitElectromobilityEnergy distributorFuse holderGas arrestorInsulating distributorInsulating housingInverterLightning protectionLightning protection housingLightning protection moduleLightning rodLoading deviceOvervoltage protectionPhotovoltaicPhotovoltaic system solutionPhotovoltaic systemsRail conductorSurge protection deviceSurge Protection EnclosureSurgeControllerSystem solutionTerminal blockfrom the following manufacturers:Manufacturer overview catalogue Combined arresters - eletric:ABBDEHNEatonFinderHagerOBOPhoenixSchneider Electric
Heating actuator - A comfortably warm bath after getting up or a cool bedroom at night - automatically. Who does not want that? Modern building automation makes it possible. The interaction of room temperature controllers, heating actuators and valve drives offers almost unlimited possibilities. The setup can be set up in all rooms according to the needs of everyday life.What are heating actuators?If you want to regulate the temperature in the room, in the apartment or in the entire building automatically, heating actuators play a central role. In principle, these are switching actuators. However, these are not equipped with mechanical relays. Thermoelectric valves (low ohmic loads) work here, which use electronic circuits (Triac) to ensure closed hot water circuits or chilled water (chilled ceiling). As a result, these devices are noiseless and wear-free.How is room temperature controlled via a heating actuator?The control difference determined by a KNX room temperature controller, i.e. the difference between the setpoint temperature and the actual temperature, is converted into a command value telegram. It is sent to the corresponding channel of the heating actuator via the KNX bus. Connect the thermoelectric (conventional) actuator to the duct using a suitable cable (e.g. NYM-J 3x1.5). The heating actuator can switch directly (1 bit) or independently process a received 1-byte command value signal internally. With the latter, the KNX bus is relieved because there is no flood of control telegrams from the room temperature controller to the actuator. Only the calculated control difference is sent to the actuator as a 1-byte command value telegram (0-100%). This converts the information into switching signals (on/off) directly to the assigned heating channel. This is called pulse width modulation (PWM). TIP:Make sure there are enough control channels on the heating actuator, ideally at least one per room. This creates maximum flexibility when controlling. The following small example illustrates the rough functionality, not the actual, manufacturer-specific control algorithm:The current temperature (controlled variable) is 20 degrees Celsius. The desired room temperature is 25 degrees Celsius and represents the set value for the controlled variable (command variable). The difference between the desired room temperature (set value) and the current temperature (actual value) is the control difference. The control difference is 5 degrees Celsius and is used to determine the manipulated variable that influences the room temperature. Assuming the manipulated variable is 20%. This value is sent to the heating actuator in the form of a 1-byte telegram (0-255 = 0-100%). The value 51 is therefore transmitted to the actuator. The time for opening/closing the actuator is stored in the parameters of the actuator using ETS. You can find this time in the properties of the respective 230V AC or 24V DC thermoelectric actuator. For example, the actuator takes 2 minutes to fully open. With a command value specification of 20%, the actuator would switch on the valve drive for 24 seconds (20% of 2 min.) and switch it off for 96 seconds. This process is repeated until the room temperature controller calculates and sends another command value specification. Depending on the manufacturer of the actuator, you can integrate several actuators per channel.How do I find the right heating actuator?The selection of a suitable heating actuator is linked to certain requirements. Answering the following questions will help you make a decision:How many heating circuits does my system have?How many actuators do I have per heating circuit?Do I want to install the heating actuator centrally or directly in the heating circuit distributor?Do I want to protect the power supply of the device via a connection for auxiliary voltage?With what voltage do the actuators work?Which functions should the heating actuator have?Do I prefer a certain brand?and many more The range of functions of a heating actuator in particular can differ depending on the model. Things to keep in mind include the following:Is it controlled with 1bit (switching/PWM) and/or 8bit (continuous) control values?Is direct control with a temperature value possible via the KNX bus?Does the device have an integrated temperature controller?Are the setpoints saved in the event of a bus voltage failure?Is there an emergency operation if the cyclic command values fail?Are different operating modes available (comfort, night, frost protection, summer mode or winter mode)?Is there a short-circuit detection and a voltage failure detection?Does the device have a pump shut-off? High comfortDepending on the model, it is possible to set a minimum comfort temperature for the underfloor heating. An additional sensor measures the temperature of the floor and keeps it at your comfort level. This is very pleasant in barefoot zones such as a bath.Depending on what value you place on the individual properties, the range of products can be limited to just a few models.Can I connect a heating actuator directly to the actuators in my heating circuits?In the case of a decentralized installation, for example in the heating circuit distributor, models with L and N connections can be used for direct connection of the actuators.Are KNX actuators really bad?Thermoelectric actuators are not wear-free and should be replaced every year. That is why expensive KNX actuators, which combine the KNX actuator and actuator, have not caught on and are disappearing from the market.Image: Jung Triac 2336-REG-HZR-HE 6-fold KNX heating actuatorHow are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.How do I prevent rapid wear and tear on my valve drives?The ETS parameter 'Flush' minimizes wear and tear on valves that are rarely used, for example in summer or in bedrooms. This function prevents rapid calcification of the heating valves. Good to knowWith actuators, a distinction is made between NC (normally closed) and NO (normally open). NC drives open when power is applied. In NO actuators, the current closes the valve. Please bear this in mind when planning your heating system, as it is ultimately your personal decision. In the event of a power failure or defect, NC drives close and you quickly notice a malfunction. These drives only consume electricity when heating. On the other hand, drives that open without current are more efficient during the heating period. In this case, switching off the pump by the heating actuator after the winter season would be advisable. Otherwise you would continuously use electricity to keep the heating closed by means of the NO actuators in the warm season.Who are the leading manufacturers of KNX heating actuators?The leading manufacturers of KNX heating actuators at eibabo® are, for example, ABB, Berker, Busch-Jaeger, EIBMARKT, Elsner, Gira, Hager, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben. We have more than 25 years of experience in the field of building automation and have arranged the order of the products in this catalog accordingly.

Combi i/o device - Combi IO devices are essential components of complex building automation. Find out here how to use the high-quality IO devices and what options there are for your installation. In any case, these devices increase the efficiency of your installation. Learn more about these modules and why it is so important for them to work properly.What is an IO device?An IO device - also known as an input-output module - enables communication between a computer system and a peripheral device. This type of processor communication between devices increases a computer's capabilities. The operating system is enabled to connect to the outside world. Communication and interaction takes place through sending and receiving information. Possible input information are, for example, signals from user inputs or binary inputs. Output signals are sent by the system or converted into actions as manipulated variables by actuators. With the use of a multifunctional input module, the work can be carried out more efficiently and accurately. Typical IO devices include:KNX universal interfacesKNX universal controllerKNX switching actuators with integrated binary inputsKNX button interfaces with outputs for LED controlspecial KNX room controller with a variety of special functions  TIP:An IO device can interface with a large number of bus protocols, for example PC Cards, USB, PCI, VMEbus and FireWire. In this eibabo® category you will find, for example, KNX devices with multiple functions from top manufacturers such as ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben.What are the most important functions of an IO device?An IO device is an essential link in the control chain and closes the gap between your computer system and the external devices. It can perform multiple functions including:Communication between the devices in the systemAn IO device assumes several functions within the scope of device communication. This includes the transmission of status messages, the sending of commands and the transmission of information.communication to the processorFull communication with the processor includes recognizing its own IP address, decoding and accepting commands, and reporting status updates.error managementAn IO device detects different types of problems that can occur between the computer system and a peripheral device. These can be mechanical problems, such as a used printer cartridge or errors that occur during data transfer.Image: ABB IO actuator 8-fold IO/S8.6.1.1timingIn order to be able to correctly manage the flow of information between the system and the external device as part of time management, the IO device accesses the internal resources of a computer.data bufferingOne of the most important functions of an IO device is managing the transmission speed between memory, processor and other external devices.How and where can IO devices be mounted?There are many options for mounting IO devices and they depend on your existing installation. Choose from the following options:Panel mounting - the unit is bolted to a chassis or attached to a panelRack mounting - the device fits into a standard housing, such as a 19-inch rack or similarInstallation on DIN rails - the device is attached to one of the common DIN rails or G-railsfree installation - the device has a stable housing and is set up in a freely selectable placePrinted circuit board assembly - the device plugs directly into computers or is attached to the case What advantages do IO devices offer?Depending on the IO device involved, each can play a significant role within an effective operating system. In a programmable logic controller (PLC) and other operating systems, these devices offer the following advantages:a compact design saves space in almost any assembly environmentthe installation can be done remotelyHardware and associated costs can be savedthe wiring and cable setup is simple and clear What are the properties of the inputs and outputs on the IO devices?As a rule, IO devices offer digital channels, analog channels or a combination of both variants. The digital inputs and outputs handle low-level on-off signals. Analog inputs recognize signals such as current, voltage or frequency. Devices with combined channels often process the signals using analog-to-digital converters.The input channels of a device are differentiated as single-ended (SE) or differential (DI). Single-ended inputs consist of two contacts, one of which carries a voltage. The other is connected to ground. Such installation is simpler and cheaper than differential signaling. However, the inductance of the signal line and the difference in ground voltage between the transmitter and receiver will cause noise interference. Differential communication uses two mutual signals on two paired contacts. The difference between the two signals represents the meaningful signal value. Common-mode rejection prevents noise interference. Differential inputs respond to the voltage difference between the two contacts. These are therefore suitable for low-voltage, long-distance and high-resolution applications. The type of input channels your device has can usually be found in the product description. For example, if you have a 16SE-8DI device, it offers 16 single-ended and 8 differential inputs.isolationCertain areas of the electrical system can be isolated from others. This avoids unwanted current flow or signal flow between the areas.For isolation, please distinguish between channel-to-channel isolation, isolated analog input, isolated analog output, isolated digital input, and isolated digital output.  Catalogue content:In this eibabo® catalogue Installation bus systems > I/O device for bus system you will find items from the following product groups:Item overview:Blind controlCentralAccessControl deviceControl elementControl panelControl unitDrive elementDriver moduleEngine control unitHeating actuatorHome serverInput moduleInterfaceJunction boxLight actuatorMixing moduleMulti-controllerOutdoor areaRadio systemSecurity adapterShutter actuatorSmartphoneSun protection actuatorSwitching actuatorSwitching outputUniversal interfaceWireless solutionWireless switching outputfrom the following manufacturers:Manufacturer overview catalogue Combi i/o device:ABBBusch JaegerGiraHagerLingg & JankeMetzSiedleSomfyWaremaWindowMaster
