Rope light - LED strips are considered flexible and energy-saving lighting alternatives. But what criteria do I use to select an LED strip from a multitude of offers? How long does an LED strip light last? Many questions, to which we will give answers in the following article.Why are LED strip lights so popular?When LED technology became suitable for the masses and was available inexpensively everywhere, completely new and very flexible possibilities for the decoration and lighting of houses, apartments and other areas of life opened up for us consumers. Small dimensions, flexibility, enormous service life, good light output and different color rendering are still the most important positive properties of LED light strips. Of course, saving high energy costs and the lack of alternatives to LEDs also play an important role. Constant competition between manufacturers also leads to falling production costs and end consumer prices. Many of the products are operated with 12 V or 24 V and are therefore not dangerous in use.Where are LED strips used?The areas of application of the LED strips are hardly limited. Thanks to the use of high-power LEDs, you can use the products as the main light. But LED strips are also ideally suited as decorative lighting on and in cupboards, in various niches or to illuminate the work area in the kitchen. In the commercial sector, you can use it to illuminate goods and offers in shop windows and shelves. TipUnder no circumstances should LED strips be severely bent or kinked. This can break circuit paths or damage LEDs, resistors and contacts. You can achieve breathtaking lighting effects with RGB strips or color-changing strips. Typically, the color and brightness of such a band is controlled by a remote control. You can adapt the lighting to your current mood, especially in quiet places. Of course, waterproof versions are also available. You can light up gardens, facades, terraces or use them to simulate the daily routine in the aquarium. Car lovers use colored LED strips to illuminate the underbody of the car, the rims or the license plate. In architecture, planners set great accents with LED strips. Creative solutions include colored facades and window frames, indirectly illuminated walls or illuminated baseboards.In other words: due to the wide range of design options, LED strips have become indispensable and are used in the design of almost every interior.Image: EVN SB542430509902 LED stripWhat is the difference between LED strips?The offer is huge. The Internet is full of special offers, which are made in China with the cheapest components, imported in huge quantities and sold at cheap prices. We also offer hundreds of variants here in the eibabo® shop, but the majority of them are from well-known manufacturers. It is not that easy to find the right product for individual use. So what selection criteria should you consider?Does the product come from a well-known manufacturer?How long is the lifespan?What power supply is required?Do I want monochrome or colored LEDs?Which tape is best?How many LEDs should be installed per meter?Does the product have to be waterproof?What length do I need?Does the tape have to withstand special conditions such as heat or mechanical loads?and much more So pay attention to the information in the product descriptions and put the price in the background. Why? You will find out in the next section.What affects the quality of an LED strip?All tapes look more or less the same and the reason for a price difference is often not apparent even at second glance. However, what matters most to you as a consumer is its lifespan, delivering a constant level of brightness over that period, and its power consumption. The heart of an LED is its crystal. This is created as part of a complex process that requires a lot of technology, knowledge and experience. Few companies rise to the challenge of producing perfect crystals. However, these are the basis for a high-quality end product. The lifetime of such a crystal is determined by its degradation. definitionDegradation is the aging process of the crystal, which causes an LED to become progressively dimmer over its life cycle. Degradation leads to a drop in luminous flux over time. With high-quality goods, the luminous flux drops by around 2% for 10,000 hours of operation. Inferior LEDs lose up to 20% of their luminous flux in the same time. However, this development does not only depend on the crystal, but also on the design of the LED body and its connections. An LED gets very hot during operation and the better the heat is dissipated, the more sophisticated the housing and the longer the service life of the LED. The design of the contact connections is also important. In a circuit there are usually several LED chips in series plus resistors. Surely you have already seen that with poor-quality soldering of the chips, the entire serial circuit on a certain section of the LED tape fails, or individual colors stop working.Already knew?LEDs do not emit white light. White light is created from the mixture of equal parts of all spectral colors. If none of these colors dominates, the light appears white, more precisely not colored.Depending on the type of tape, the white light color is mixed from red, green and blue light. However, this mixed white looks very unnatural. So-called RGBW tapes therefore have an additional LED, which emits high-quality white light. In other words: the production of LEDs with white light is complicated. It is usually formed by passing blue light through a yellow phosphor. Depending on the phosphor, the 'white' LED lights up more yellowish or more bluish. It is therefore important before manufacturing an LED strip to select and calibrate the individual LEDs according to various criteria. This step is time-consuming and is not carried out by all manufacturers. In particular, because the manufacturers of LED strips are not necessarily the producers of the LEDs. The use of different LEDs from different batches or producers leads to an uneven light pattern of the white light. With LED strips, the uniformity of the white glow is therefore a quality feature.power adapterThe power supply should provide enough power for the LED strip. An LED light strip with a length of 5 meters and a power consumption of 20 watts per meter requires a 100 watt power supply. Please plan an additional 10% reserve.An LED emits light in a specific direction. In order to achieve uniformity here too, lenses and other optical elements are used. The higher the quality, the better the color rendering and the lower the loss of luminous flux.How do I know if an LED strip is high quality?Now you know how (at least in part) the price difference comes about. If you want to enjoy your LED strip for a long time, invest a few euros more. The difference isn't huge, but it will save you trouble and early repairs. You can use the following tests to better assess the quality of an LED strip:tip 1Check the 'white' light the tape produces. Blue, yellow or reddish deviations should not occur. Contrasting sunglasses may make it easier to spot differences.tip 2A noticeable decrease in brightness on the last LEDs of a band indicates poor quality of certain components.tip 3If it is not possible to test the LED strip before buying it, a look at the soldering points between the LEDs and the carrier material will help. All solder points should look the same. Make sure that the conductor tracks on the carrier material are as wide and thick as possible. In the case of inferior goods, conductor tracks that are too weak lead to an increased voltage drop and thus to differences in brightness.tip 4Choose products from companies with many years of experience in the field of household lighting, including LED. They value a good reputation, have long-established contacts with suppliers and are unlikely to produce inferior goods. Pay attention to the guarantee.

Alarm control panel - Would you like to control and regulate as many functions of your KNX building automation as possible from a central location? Then take a look at our multifunctional alarm control panels. With these convenient control centers, you always have an overview of all the comfort settings, automatisms and security-related parameters integrated in the building network. Read more about the use and function of these devices below.Image: Busch Jaeger 8136/12-811 KNX Comfort PanelWhat is the KNX protocol?In order to be able to understand the full potential of the alarm control panels, you must first know the KNX standard and its possibilities.There is a growing desire for more convenience and versatility in managing the heating, lighting and security of a home or office building. At the same time, the efficient use of energy is becoming increasingly important. People want a comfortable, environmentally friendly and safe environment to live and work in. And this is where automation can make a valuable contribution. More comfort, greater security and at the same time lower power consumption can only be achieved with intelligent controls for all devices involved. However, this is fundamentally a problem, since when implementing such a system, numerous different sensors and actuators must be controlled using different command devices. Furthermore, the large number of cabling means increased construction work and more effort during installation for planners, as well as higher costs for the user. Simplification would require a system that eliminates the problems of isolated devices. And that is KNX. KNX ensures that all components communicate in a common language. It doesn't matter what kind of device you want to use. The functions can be individually adapted to your needs and include, for example:lighting and blindsSecurity systems, alarm and surveillance systemsEnergy management, heating, ventilation, air conditioningremote controlsAudio and video controlsInterfaces to systems for building maintenance and building management All these functions work with the KNX fieldbus for building automation via a single system. All components interact with each other and create a dynamic building control system. With over 500 KNX-compliant manufacturers, flexibility and choice are huge. KNX is thus the global standard for intelligent building control and ensures full compatibility between manufacturers and related products. The KNX system can be used in almost any building or open space - from a small house to a large shopping center or industrial complex.What are KNX annunciator control panels?A KNX annunciator panel and control panel are usually highly complex, room-spanning control devices, infotainment interfaces and entertainment centers. With these devices, the complete control of a KNX building automation can be implemented at a central point.Which controls are possible with alarm control panels?There are countless equipment details for complex, logical functions. These include, among others:switching and dimmingBlind controls and automatisms for shadingroom temperature controlsCentral functions and scene controlsMultimedia, IP telephony, RSS reader, intercom with image, e-mail, voice memo and graphic memoMonitoring of consumption dataDoor communication with integrated camera and proximity sensorVideo surveillance with alarm and reporting function Everything is now possible. More and more KNX manufacturers are also offering direct interfaces to other home automation systems. These include Bang & Olufsen (B&O), Philips, Siemens Logo, Siemens SPS, CoDeSys, Beckhoff, Omron, Mitsubishi and many other systems. The menu structures of the KNX signaling control panels are partly already implemented or completely freely parameterizable.What should I look out for when buying a KNX annunciator control panel?The requirements for operating your building automation can be quite different. Depending on the type and complexity of your system, a simple device may be sufficient or a complex device may be required.Saving TIPIf it is 'only' about basic functions such as dimming, setting blinds or controlling the heating, we recommend our high-quality KNX push-button sensors. These can also be parameterized individually, look smart and are significantly cheaper to buy.This results in some purchase criteria that you can consider when making your choice:What is my budget?Do I need a complex annunciator control panel at all or can I achieve the same result with alternative devices (e.g. a push button sensor)?Which functions do I want to map?What color and design do I like (glass, stainless steel, plastic)?How should it be operated (keys, touch)?Should the bus coupling be integrated?What other interfaces are required?Where and how is the device installed (surface-mounted, flush-mounted)?Do I only need the control element or also mounting material and frame?Should a possible display be in color or is a monochrome variant sufficient?Is a special degree of protection necessary (e.g. for outdoor installation)?and more What should be considered during installation and integration into the home network?The devices are very complex. You should therefore note that commissioning can also be very time-consuming. Integration into a network via KNX IP router (routing & tunneling protocol) or KNX IP interface (tunneling protocol) is often necessary for full functional use, depending on the required protocol. Therefore, please ensure that you also lay a network cable in addition to a 230V AC power supply and the KNX bus cable. designeibabo® offers versions in high-quality stainless steel or with the finest capacitive glass surfaces as well as individual frame designs.

Impulse switch - Do you want to be able to switch lighting from different places? Or should the light be switched on centrally in different areas of the building? No problem. We will explain to you the possibilities offered by the use of impulse switches. Benefit from our huge range of high-quality impulse switches from well-known manufacturers. Favorable prices, numerous secure payment methods and worldwide shipping make the eibabo® technology store a leading specialist electronics centre. Definition:Impulse switches are electromechanical or electronic devices for the simple and energy-saving control of lighting or other consumers. Impulse switches are also referred to as impulse switches or remote switches.How does a impulse switch work?The impulse switches are switches which are actuated electromagnetically or electronically. These are also known as impulse switches or remote switches. The operating principle is similar to that of a classic ballpoint pen, except that it naturally works without electricity. Impulse switches switch on with an electrical impulse at the control inputs and switch off again with another impulse. The distance to the pulse generator is irrelevant. From a technical point of view, impulse switches are bistable relays or flip-flops, since they have two stable rest positions. Each time the connected button is pressed, the impulse switch receives an electrical impulse. This causes a change in the switching status, which is stored mechanically or electronically until the next pulse. This is the essential difference to a monostable relay. This only switches 'on' as long as a connected button is pressed and then automatically returns to the initial state 'off'.What is the difference between electromechanical impulse switches and electronic impulse switches?Electromechanical impulse switches are comparable in structure and function to an installation contactor. In addition to the housing, this consists of the excitation coil, coil core, metal armature, switch contacts and armature return spring. Flowing current creates a magnetic field in a coil and the metal armature is attracted. The switching contacts close. As soon as the coil no longer generates a magnetic field, the armature is returned to its original position by spring force. Unlike an installation contactor, however, the switching contacts of the electromechanical impulse switch do not open as a result. These remain closed by means of a locking mechanism. Only a further impulse causes the latching mechanism to change and the associated opening of the contacts.Electronic impulse switches switch using transistors, which work as electronic switches and influence each other. A so-called bistable multivibrator is created. The current switching status is always determined by the previous status and is not stored in a locking mechanism but electronically. The switching process is completely noiseless. Since no mechanics are used, the wear and tear of electronic impulse switches is lower.Where are impulse switches installed?Impulse switches are usually offered in two designs. On the one hand as an REG device (= modular installation device) for mounting on a DIN rail in the electrical distribution. On the other hand, the devices are installed in switch boxes or junction boxes. This installation can be flush-mounted or surface-mounted.What are the advantages and disadvantages of impulse switches?In electrical installations and in electrical distribution installation, impulse switches can be used instead of off switches, changeover switches and cross switches. In this way, several switching points can switch the same load. The wiring required for the surge circuit can usually be implemented more easily and often more cost-effectively than with other circuits. You can also use impulse switches with three or four switching states. With such impulse series switches, you can map more complex switching processes in a relatively simple way. A classic application is switching the same load (e.g. a lamp) from several switching points. You know this scenario from:Staircases in the private environment or public buildingslong corridors in company buildingsRooms or halls with multiple entrances in hotels or production facilities In these cases you will usually find buttons on all floors or at all entrances in order to be able to switch the lighting on and off from all locations.Good to knowWhen 'switching', the load current only flows through a potential-free switch contact and not through all buttons. This reduces the susceptibility to failure. If a button fails, the circuit with the remaining buttons will continue to function.In addition, there is the option of centrally controlling several impulse switches. Using an additional module, all connected impulse switches can be reliably switched on or off. This happens regardless of the current switching position of a respective impulse switch. Practical example: An employee in an office building switches off the lighting in a central location at the end of a working day.However, electromechanical impulse switches also have a disadvantage. The devices produce a clicking noise when switching. This can be perceived as annoying. During installation, please ensure good sound insulation of the electrical distribution. Also consider this when mounting in the switch boxes of bedrooms or children's rooms. In these cases, use noiseless electronic impulse switches.Image: Eltako ES12DX-UC impulse switchFor what performance are impulse switches designed?The current impulse switches are designed with switching coils for 12 V AC/DC, 24 V AC/DC or 230 V AC. Impulse switches with monostable switching relays constantly require a small amount of electrical energy, while electronic impulse switches with bistable switching relays work with practically no standby loss.Where can I get high-quality impulse switches at particularly low prices?You can buy impulse switches for electrical distribution installation at low prices from eibabo®. We carry a large selection of high-quality impulse switches and electrical remote switches. But you will also find remote switching relays, installation remote switches, cascade circuits, multiple control centers and call-acknowledgment relays with us.

Switching relays - How does a relay work? What different relays are there? Where are relays typically used? Which relay is right for your project? Learn more about switching and controlling circuits here. Switching relays are used in many different applications, for example in automated factories, in vehicles and in household appliances. The switching relays offered by eibabo® are high quality, inexpensive, versatile, reliable and universally applicable. The best-known manufacturers in our range are Wago, Schneider Electric, Bircher, Finder, Grothe, Hima, Issendorf, Metz Connect, Phoenix Contact, Siemens, Tele Hase and Omron.What are switching relays?A switching relay is an electromechanical device used to control electrical circuits. It consists of one or more electrical contacts that are controlled by one or more magnetic coils. When the solenoid is activated, the contacts close and current flows. When the solenoid is de-energized, the contacts open and current does not flow.Image: WAGO 788-312 socket with relayWhat should be considered when buying a switching relay?In view of the enormously large selection and the numerous specifications, choosing the right switching relay is not easy. Before you decide on a specific model, you should plan your switching device exactly and define the exact task of the relay. This results in the type of switching relay required. Now select a suitable relay for your project based on the following considerations:Is the installation fixed or moveable? Switching relays for mobile equipment should be able to withstand vibration and shock.What kind of contacts should the relay have? How many? What is the switching current and the switching voltage?Which current magnitudes and voltage magnitudes occur? Consider the nominal voltage of the coil, the coil current, the dropout voltage and pick-up voltage of the coil and resistances.Which response times and release times should not be exceeded?What is the expected switching frequency?What requirements do I place on the service life of the mechanical components?In which environment and in which temperature range is the relay used? How does a switching relay work?Depending on the design, relays can have a simple or complex structure. However, the basic functional principle is the same. The heart of a relay is the coil with an iron core. When current flows through the coil, an electric magnetic field builds up. A ferromagnetic armature responds and is attracted. This movement connects two contact springs together. The so-called working contacts in the relay close (normally open).Good to knowSwitching relays have electrical ratings for the coil and internal switch contacts. The coil voltage is the voltage required for the coil to operate properly. The circuit voltage rating represents the maximum rating of the switch contacts and should not be exceeded.In some designs, so-called break contacts are opened when the magnetic field is created. These are called openers. There are combinations of openers and closers, so-called changeover contacts or changeover contacts. As soon as the coil no longer generates a magnetic field, the armature is returned to its initial position by spring force. The working contacts are no longer closed.In addition, there are numerous other relay types, some for special purposes. As a rule, these relays differ in the functional principle, in structure and size, in the switching capacity and in the contacts. A few examples briefly explained:For example, thermal relays use a bimetallic strip that bends when heated, opening or closing the contacts. Thermal relays are commonly used in circuit breakers.Photoelectric relays respond to light pulses and open or close the contacts accordingly. These are used, for example, in photo flash devices and surveillance systems.In static relays there are no moving contacts. The switching action is triggered by thermionic valves, transistors or amplifiers. This list could be continued, for example with time delay relays, solid state relays, coupling relays, distance relays, differential relays, undervoltage relays or overvoltage relays. There are separate categories for many of these special shapes here in the eibabo® shop. Please use our intelligent search.What are switching relays used for?Relays allow a low current circuit to control or switch one or more higher current circuits. Switching relays in a variety of designs are required in electrical distribution and electrical installation. The switching relays from our shop can be used for all interface applications in demanding control systems. This allows you to connect highly sensitive and almost powerless controls of a PLC, a control system or a process computer with the power level of a machine or another connected consumer.What are the advantages and disadvantages of switching relays compared to other switching mechanisms?Switching relays offer the following advantages:Switching relays are inexpensive.The components are robust and tolerate voltage peaks and current peaks.Switching relays provide potential-free isolation from the load circuit.The heat development is low. Cooling is not necessary.Switching relays switch both very low signals and high-frequency power.In many cases, the current switching status can be seen with the naked eye.Thinner gauge wire can be used to connect the control switch to the relay.Relays make it possible to direct current to a device via the shortest path. This reduces voltage losses. TIP:Semiconductors, semiconductor circuits or transistors are used as an alternative to relays. These offer an extremely fast response time. However, switching relays also have disadvantages:The mechanical components are subject to a certain amount of wear.Switching relays react sensitively to shocks and mechanical loads.The switching actions are audible.The response times and fall times are very long compared to semiconductors.The insulating capacity often depends on the environmental conditions. Why are protective devices used on some switching relays?If a relay is switched off and the coil suddenly loses current, a large voltage spike can occur. For this reason, protective mechanisms such as resistors or diodes are switched across the coil of the relay. These reduce or prevent the risk of these voltage peaks flowing back into the control circuit and damaging sensitive components. Resistors last longer, diodes provide more efficient protection against voltage spikes. You can judge what kind of protection is required based on the sensitivity of your components in the connected circuit.Why doesn't my switching relay switch off anymore?When choosing the right relay, you should pay attention to the loads that occur. Current peaks when switching can cause the contacts to 'stick' or 'weld' together. If the relay is not designed for the loads that occur, the surfaces of the contact springs will change over time. This can result in the contacts no longer opening when the relay is de-energized. Conversely, loads that are too low can also lead to a similar effect, since the self-cleaning process no longer takes place.

Electricity meters - Have you always wanted to know how much energy individual devices in your household consume? This catalog from the eibabo® shop offers you the right measuring instruments for this. Here you can get high-quality electricity meters and many other meters at top conditions. In our modern home we use numerous electrical devices. In addition to lamps, washing machines and refrigerators, media technology is a major energy consumer. Televisions, computers, chargers for smartphones and building automation are powered by electrical energy. Although some of these devices also help save electricity, it is interesting to know how much energy they actually use.What are electricity meters?Electricity meters are devices for displaying electricity consumption or energy consumption in electrical systems. AC induction meters are predominantly used in households, which directly display the consumed kilowatt hours. To find out how high your energy consumption is in a certain period of time, you need to take two measurements. Subtract the value of the second measurement from the value of the first measurement.Image: ABB B23 113-100 three-phase meter M-BusWhat types of electricity meters are there?There are two main types of electricity meters. These are used by the utility companies. On the one hand there are the electromechanical meters and on the other hand the so-called intelligent meters or smart meters. If you operate a solar system and feed electricity into the grid, you need a third type of meter, the bidirectional meter. These measure the current drawn and the current fed in. As a rule, you have little influence on the electricity meters that come from your energy supplier. These are installed where the power lines enter your building. This catalog is about electricity meters, which you can also install. This allows the consumption of a specific section of your installation or the consumption of an individual end device to be measured.How is an electromechanical meter constructed?Electromechanical induction meters are widely used and can be found in many homes. These contain an electrically conductive, non-magnetic, rotatable 'Ferraris disc'. The disk is driven by the interaction of magnetic fields generated by two electromagnets.Magnet 1 is powered by the current from the incoming power linesMagnet 2 is powered by the current demanded by the building's electrical circuits The rotation of the disk is slowed down by two permanent magnets, which exert a proportional opposing force. The aluminum disc drives a scrolling mechanism that displays kilowatt hours or fractions thereof.How does a smart meter work?Electronic electricity meters have been on the market for several years. The current standard for electronic electricity meters are digital electricity meters and so-called smart meters. These work in a similar way to electromechanical electricity meters. Instead of mechanical moving parts, they contain a battery and a communication chip. The chip sends meter readings wirelessly to a collection point. This happens several times a day depending on the time of day. The data is usually transmitted to the electricity supplier every quarter of an hour via power lines, mobile communications or high-frequency networks. Already knew?The chip is also known as an encoder or ERT device. This uses the same frequency as many cordless phones. However, the device is designed to avoid interference. The battery in the communication chip in digital electricity meters is designed for a service life of 15 to 20 years.What are the advantages of measuring with an electronic electricity meter?With an electronic electricity meter, you can not only determine how much energy you use, but also when. At first glance, this may be less important additional information. But knowing exactly when and how much electricity you are using can save you a lot of money. Electricity prices vary throughout the day. When demand is high, electricity costs more than when demand is low. Constantly rising energy costs are leading to deregulation of the electricity markets. In the future, utilities could offer electricity tariffs that bill for the electricity provided based on the time of use. This would be a significantly fairer billing method than the current variant, which is based on average costs.smart gridSmart grids are intelligent power networks that take generation, storage and consumption into account. This allows fluctuations in power in the network to be compensated. Networking and coordination is carried out using modern technologies and decentralized energy management systems.Smart meters can also be read remotely. Utility companies thus save operating costs and working time. Electronic electricity meters are therefore an essential part of the so-called smart grid. The devices help you to question your habits and save money if you use your electricity off-peak. Think of buying an electronic electricity meter as an investment in your future.How do I find the right electricity meter?Modern electricity meters can be used to display electricity consumption in real time. Especially in the KNX area, intelligent electricity meters offer many advantages. These support you with load management within your installation and with the monitoring of services and end devices. This saves you money and time because you can make adjustments according to your consumption profile. The use of data loggers or programmable logic controllers makes it easier to display, control, analyze and monitor the data. You can integrate models with a KNX interface directly into your building automation system using Engineering Tool Software (ETS). But which things are still important when buying?number of phasesWhen choosing an electricity meter, please consider how many phases are required. The most common models are single-phase or three-phase. If your current system that you are getting your data from is single phase, you will need a single phase electricity meter. If the electrical system is three-phase, use a three-phase electricity meter. As a rule, the devices can be mounted on a DIN rail. The measurement is carried out flexibly for various performance parameters such as:True RMS Voltage (Vrms)True RMS Current (Irms)Active power (kW)Active energy (kWh)Apparent Power (kVA)Apparent energy (kVAh)Reactive Power (kVAR)Reactive energy (kVARh)Power Factor (PF)frequency The devices can be used both on the primary side of the low voltage and on the secondary side of the medium voltage and high voltage.The ampPay attention to how many amps you need for the system. Commonly, smart electricity meters support 60 amps, 100 amps, and 200 amps. The right choice depends on your power system. Using a 100A electricity meter for a system that requires 200A would be impractical.Bus systems and networksIntelligent electricity meters communicate via various media and protocols. Please determine in advance which communication protocols will be used. Well-known fieldbus systems are AS-Interface, CAN, CANopen, M-Bus, EtherCAT and others.

Installation relay - What is a relay and how does it work? What types of relays are there? Where are relays used? And which relay suits your project best? Here you can learn more about switching and controlling electrical circuits. Installation relays are used in many different applications. You will find relays in domestic electrical installations, in electrical appliances, in commerce and industry, and in vehicles.A look into historyThe first relay was invented by the American J. Henry in 1831 and was based on the electromagnetic principle of operation. Henry used the relay in his university lab as a 'gimmick' to entertain his students. However, it was not yet possible to switch gears. The first switching relay was invented by Samuel Morse in 1837. Morse refined Henry's device and adapted it to transmit signals (the Morse code) down miles of wire. This was also the basis for the telegraph.Did you know that the world's first computer was also built with only relays? It was a development by Konrad Zuse, which was presented in 1941. A lot has happened since then and relays are no longer used in modern computers. Nevertheless, the relay is still an important and popular component in electrical installations today. Think, for example, of switching on and off the lighting in the stairwell. The circuit works regardless of which floor you are on. However, there are numerous other areas of application. That is why different installation relays are also available in the eibabo® shop. Simply browse through our virtual catalogue. You will surely find some high-quality and inexpensive installation relays that arouse your interest.Image: Eltako ER12-110-UC switching relayWhat are relays?Relays are components within electrical installations of all kinds. They are mainly used as circuit breakers and control switches in electrical devices or are used as important components in many control processes. There are numerous types of relays, which differ in detail. The manufacturers develop the devices for special tasks and adjust the triggering characteristics accordingly. Relays that are often bought in this catalog are coupling relays, power relays, switching relays, interface relays, semiconductor relays and many more. The basic operating principle of a relay is to open and close circuits or contacts by reacting to electrical quantities such as current or voltage.How are relays differentiated?Relays are classified according to various criteria. These include:the type of physical inputs to which the relay respondsthe area of application that the relay assumes in control systemsthe structure of the device design and the principle of operationthe switching capacitythe shape and sizeand some others A relay consists of three main elements:entering / entering a valuethe intermediateof execution / actuation by actuator If we look at the type of physical input variable, we distinguish between electrical, thermal, optical, mechanical, magnetic or acoustic relays. NoticeNot all relays work with fixed physical quantities. Differential relays, for example, react to the difference in values. Polarized relays respond to a change in sign of a specific value. The acquisition of the measurand is the primary element of the relay. This converts the input value into another physical quantity. The receiving element can have different designs depending on the purpose of the relay and the nature of the physical quantity. In the case of a latching relay or a voltage relay, the receiving element consists of an electromagnet. In the case of a pressure relay, this can be a membrane or bellows. The sensing element of a level relay is usually a float and so on.The intermediate element compares the input value with the specified limit value of the device and, if it is exceeded, transmits an impulse to the executing actuator.The actuator transmits the pulse from the relay to the working circuits. Each relay basically contains a control circuit and one or more operating circuits. Depending on the type of actuator, the relays are divided into contact relays and contactless relays. Contact relays act on the outgoing circuit with the help of electrical contacts. Their closed or open state allows either full closure or full mechanical break of the work circuit. Contactless relays act on the working circuit by a sudden change in parameters in the control circuit. This is achieved via resistance, capacitance, inductance or a change in voltage level or current level.How does an installation relay work?Depending on the requirement and application, relays are simple or complex. However, the basic functional principle does not differ significantly. In the center is the coil with an iron core. When current flows through the coil, an electric magnetic field builds up. A movable, ferromagnetic armature reacts to this magnetic field and is attracted. This change in position connects two contact springs with each other and the so-called working contacts in the relay close. In this case, the relay acts as a closer. In some designs, so-called break contacts are opened when the magnetic field is created. These are called openers. Combinations of openers and closers are also possible. These are changeover contacts or changeover contacts.Already knew?If the coil of a relay is suddenly de-energized, high voltage peaks can occur. Therefore, depending on the model, resistors or diodes are used to prevent these voltage peaks from flowing back into the control circuit. Sensitive components remain protected.As soon as the coil no longer generates a magnetic field, the armature is returned to its original position by spring force. The make contacts are no longer closed and the break contacts are no longer open.What are Solid State Relays?More and more relay functions are currently being taken over by semiconductor circuits, so-called solid-state relays (SSR). A solid state relay is an electronic device that turns on and off a high power circuit with low voltages. There are no mechanically moving elements in this type of relay. The device consists of:a sensor that responds to an input signala solid-state electronics with high-performance circuitry Solid state relays can be used with both direct current and alternating current. With the help of thyristors and transistors it is possible to switch currents of several hundred amperes. Compared to electromechanical relays, semiconductor relays have a significantly higher switching speed. Solid-state relays are less suitable for switching under short-term overload conditions. Compared to electromechanical relays, solid state relays offer the following advantages:smaller dimensionshigh switching speedsnoiselesspowerfulmore energy efficientspark-free circuitmaintenance freelong lifetimelow sensitivity to adverse conditions What should I look out for when buying an installation relay?In the eibabo® shop there is a huge selection of different relays with numerous specifications. Choosing the right installation relay can be difficult. Before you buy, you should determine the function of your circuit and then define the task of the relay. Then select a suitable relay for your project. Decision criteria include:What kind is the physical input quantity?Will the device be subjected to vibration and shock?Where will the installation take place?Are dust, moisture or temperature fluctuations to be expected?What is the switching voltage and the switching current?Which current magnitudes and voltage magnitudes occur?What is the expected switching frequency?What requirements do I place on the durability of the relay?Are special functions or additional programming required? Notice:When switching active and inductive loads, opening the circuit for the contacts is the most difficult. In this case, arcing occurs, which puts a lot of strain on the contacts.
