The CR-M120AC2 plug-in interface relay is a miniature relay designed for use in a compatible ABB CR-M socket. Once plugged in, the combination of relay and socket can be seamlessly mounted on a DIN rail. This relay operates with a nominal control voltage of 120 V AC and features a 2 c/o (SPDT) output with contacts rated for 250 V / 12 A, allowing multiple circuits to be switched with a single input signal. The relay is equipped with a built-in test button that enables manual operation and locks the output contacts, facilitating testing and commissioning. Additionally, the relay has an integrated LED that provides a visual indication of the energization of the relay coil. Standard sockets, logic sockets, plug-in function modules, holders, and markings are available as accessories.
