CR-M Pluggable Miniature Relays

Pluggable miniature interface relays

The ABB CR-M pluggable miniature interface relay range is used for electrical isolation, amplification and signal matching between the electronic controls – PLCs, iPCs or field bus systems – and the sensor / actuator level. The CR-M range offers up to 4 contacts in one relay and an integrated test button that makes circuit checks quick and easy. There are 13 different coil voltages to suite applications worldwide. A gold contact version is also available for switch-sensitive signals. Complete versions consisting of a relay, socket, holder, marker and function module are avaialble in this range.
