Optocouplers - Do you know what optocouplers are? These are semiconductor components that are capable of transmitting electrical signals between circuits over a short optical path, even if they are completely electrically isolated from one another. This is also referred to as galvanic isolation. In order to get a better idea of how it works, communication via Morse code can be used for comparison in the broadest sense. Here, too, one person can communicate with another by sending light signals. This receives a command, evaluates it and reacts accordingly. However, there is no return channel. Communication therefore only works in one direction. In the case of an optocoupler, for example, this can concern a signal transmission that must be established between high-voltage and low-voltage devices. With high-quality optocouplers from the eibabo online shop, you are choosing reliable components for transmitting signals between separate circuits.Catalogue content:In this eibabo® catalogue Relays > Optocoupler you will find items from the following product groups:Item overview:Changeover relayContactor relayControl unitCoupling moduleCoupling relayIdentification plateIndustrial relayInscription platesIsolation moduleLabelLoad relayMaster packageMini optocoupler moduleMiniature switching relayOptocoupled moduleOptocoupled relayOptocouplerOptocoupler modulePCB relayPower optocouplerRelayRelay socketRelay terminalSemiconductor switchSemiconductor switching deviceSocketSolid state relayTransistorfrom the following manufacturers:Manufacturer overview catalogue Optocouplers:ABBFinderMetzMurrelektronikPhoenixSchneider ElectricSiemensTriaxWAGOWeidmüllerWeidm?ller
Isolating switch amplifiers - With an isolating switching amplifier you create a so-called galvanic isolation between two circuits. In this way you can, for example, safely separate potentially explosive areas from non-hazardous areas or high-voltage areas from low-voltage areas. At the same time, however, with this device you ensure that, despite the electrical isolation, the exchange of services and signals is maintained. Depending on the design of the isolating amplifier, the non-electrical signal transmission is established via inductive, capacitive or optoelectronic coupling. You will find a large selection of isolating amplifiers, isolating switching amplifiers and optocouplers at excellent prices in the eibabo technology store. Rely on our high-performance logistics.

Line backbone coupler - Would you like to expand your smart home system and are you looking for a way to integrate additional devices into the existing infrastructure? No problem. The strength of modern building automation lies precisely in this flexibility. In this catalogue, we present line area couplers with which you can expand the topologies of your network.Living, working, security and climate protection - building automation offers many advantages for modern households. In particular, the areas of 'living comfort' and 'energy management' are strongly influenced by the possibilities offered by modern communication media and control technology. Numerous functions in a building can be automated, from switching on the light and setting up needs-based heating cycles to organizing access control systems. It can be controlled from anywhere in the world using a computer or smartphone. When setting up simple and complex networks for the KNX building automation, line area couplers are used, among other things.How is a KNX network structured?Within a KNX network, we distinguish between segments that are networked with each other and have a hierarchical structure. The segments are called lines, main lines and areas. You can think of this as a tree whose trunk splits into branches and further into twigs. The branches represent the smallest unit and are called 'lines' in the KNX network. Each line consists of a KNX bus line, a power supply and the participants. A 'main line' would be the branch that connects several lines into an 'area'. The area line represents the trunk that connects multiple areas. A well-organized structure makes sense, especially for larger networks. Due to the structure in segments with different tasks and priorities, the system remains clear and can be expanded at any time.What is the main task of a line area coupler?To control data traffic, a line area coupler connects two KNX lines with each other. The device ensures galvanic isolation between the lines. This means that each KNX line can be operated electrically independently of the other lines. TIP:A separate KNX power supply is required for each line, main line or area line. Theoretically, 255 KNX participants can be integrated into one line. Due to the average power requirement of KNX devices, cable lengths and other limit value definitions, a maximum of 64 KNX participants (devices with bus coupler) are defined per line. For a standard single-family house, this is usually sufficient with optimal planning.What possible uses does a line area coupler offer?Line couplers or area couplers are also required to create larger KNX topologies with a large number of KNX devices. The smallest topology is a line, which is powered by a KNX power supply. A single line does not yet require a line coupler.At line levelWhen using a 640mA power supply, the number of participants can be significantly increased using line amplifiers. Line area couplers can take over this function. The newly created sub-line has its own KNX power supply and is connected to the existing line via a line amplifier for galvanic isolation. Since the ETS (Engineering Tool Software) allows more than 64 participants per line, the participants of the sub-line can be viewed as if they were in the actual line above.At the main line levelIn the case of extensions, an additional line is usually set up. This receives a 640mA power supply and is coupled to the first line using a line coupler. This line is called the main line. Of course, 64 participants can also be connected to the main line. Up to 15 lines can be connected to this main line. This represents the maximum value of an area. Additional extensions are now also implemented using line couplers (area couplers, depending on the assignment of the physical address and parameterization).At the area levelThe line that connects areas together is the backbone line. This means that up to 15 areas with several tens of thousands of KNX participants are possible. KNX IP routers can connect two KNX installations by means of communication via the routing protocol. This requires an existing network connection between the installations (buildings or parts of buildings). A KNX IP router can use the routing and tunneling protocols in parallel, while a KNX IP interface can only use tunneling.Image: ABB LK/S 4.2 line couplerClassic application examplesWith the use of line area couplers, you create well-functioning and optimally organized communication between the individual segments (lines, main lines, areas) of a system. Depending on the structure of a system, the individual segments can take on specific automatisms in the same room or perform special tasks via a network connection at different locations around the world. Examples for this are:the central control of the heating, ventilation and air conditioning for different workplaces in an office complexthe controlled compliance with necessary hygiene protocols in different parts of a hospital buildingthe implementation and monitoring of security concepts in a residential complex (locking systems, elevators, emergency exits, night lighting)the control of shading systems of global company branches based on the position of the sun, time zone and weather data The full rangeIn the eibabo® shop you can get all the items you need to set up simple or complex topologies.
