Enabling Power and Communication

ABB’s interface relays and optocouplers provide reliable voltage conversion between process peripherals and higher-level control systems. Our relays ensure reliable signal switching and provide electrical isolation for sensitive electronics such as PLCs in all kinds of machinery. The wide variety of pluggable interface relays with standard or logic sockets can be used for switching AC or DC loads. Suitable for extreme environments, ABB’s interface relays offer a range of different coil voltages and plug-in functional modules. Environmentally friendly, cadmium-free and lead-free, ABB interface relays and optocouplers meet RoHS requirements. Complete versions consisting of a relay, socket, holder, marker and function module are avaialble in this range.
