Interface relays

Interface relays, also known as coupling relay modules, are devices used in industrial automation, housing and general construction. They perform the function of separating inputs / outputs in systems with PLC controllers, and in electrical installations - the role of intermediary and executive elements.

Electromagnetic and semiconductor interface relays

Interface relays are most often implemented as modular devices, designed for mounting on a TH35 rail. Relay coupling modules of this design are available in the offer of two companies specializing in the production of interface relays - Finder and Relpol. Both manufacturers offer electromagnetic and semiconductor solutions.

Semiconductor interface relays have a structure characteristic of other semiconductor relays, as well as identical properties resulting from the specificity of optical transmission inside the devices. Similarly, electromagnetic relay control modules are equivalent to other types of electromagnetic relays both in terms of their properties and principle of operation.

Matching the voltage signal levels by interface relays

One of the most popular applications of interface relays is to match the levels of voltage signals. What is such an operation? Having a 24 V DC circuit at your disposal, in which it was necessary to connect, for example, a 230 V AC coil contactor, for obvious reasons it is not possible to connect the contactor directly to the circuit. However, it is possible to use an interface relay, selected so that its coil is switched on with 24 DC, while the normally open contact supplies 230 V AC to the contactor's coil.

Another application of the relay interface module can be switching a small motor on a small current loadable (e.g. 30 mA) output of the controller. Here, too, a properly selected interface relay connected between the controller and the engine will come in handy.

Interface relays - supply of control signals

In addition to matching the voltage signal levels to the requirements of circuits and devices, the role of interface relays is also to provide control signals. A frequent case during the modernization of equipment in industry is related to the modification of the need to control, for example, binary inputs of a controller or a frequency converter, having a control signal 230V alternating current. In this system, you can also use a properly selected interface relay.

Relpol and Finder interface relays - popular applications

Interface relays are devices of various designs and specificities. Their characteristic feature is the possibility of mounting in a modular housing on a TH35 rail, although the offer of Relpol and Finder, two leading manufacturers of relay coupling modules, includes relays that are also suitable for locations other than the rail. An example is the Relpol executive electromagnetic interface relay. Although the spectrum of its application is wide, it is mainly used in PLC-based systems. Made of PVC or polyamide PA (for operation in harsh environmental conditions), it is available in versions with output protection in the form of a fuse or with a common "+" or "-" pole at the output. Another example of a relay is a coil-input coupling module with the possibility of limiting the leakage current, a fuse module and a timer by Finder, with an option of DC, AC or AC / DC coils.

A very wide range of applications is characteristic of this group of relays. The second of the described relays can be installed in over 20 applications, e.g. in automatic car washes, shoe machines, lifts, cranes and winches, industrial washing machines, road lighting, wood or paper processing machines, as well as fully automated garages and car parks and generators current.
