Interface relay, coupler relay, relay coupler or PLC interface relay are interface circuits with galvanic isolation, they use voltages of 5v, 12V, 24V and other voltages for coupling in PLC or PLC offering power interface with relay. How to connect an interface relay and how an interface relay works are important classes in electrical automation, an interface circuit with a relay is very common in the industrial installation of machines and equipment. Mundo da Elétrica shows how to maintain an interface relay, how to test an interface relay and how to replace an interface relay.

Important characteristics of an interface relay. We cover the following items in this video: The interface relay can also be called a coupling relay, isolator relay, and some other names. This relay offers galvanic isolation that meets current standards such as NR12, protecting the load circuit of the power supply circuit using extra low voltage, also required by NR10. Its main advantage and characteristic is its reduced lateral dimensions, which saves a lot of space inside the panels. Another great advantage is that it is easy to replace without having to remove the cables. The relay itself can be detached from the base, making it easier to replace and reducing costs, considering that the relay itself has one cost and the base another. The operation test is very simple using a multimeter on a continuity scale and checking the switching of the contacts between closed and open at the time of energization. Parts highlighted in this video (edit notes): 00:23 - The interface relay is also known as a coupling relay. 01:39 - There are a series of relays in industrial controls and automation that are used in the most varied situations in order to protect electrical circuits. 03:03 - Even in building electrical systems, relays suitable for circuit protection must be used in some cases. 04:16 - Relays work with switch contacts that can be NO or NC.
