The ABB CR-M series pluggable miniature relays that can be used for electrical isolation, amplification and signal multiplying. As an interface they link the electronic controlling, e.g. PLC, PC or field bus systems and the sensor/actuator level. These interface relays do not use additional internal protective circuits and therefore are overload-proof against short-time variations like current or voltage peaks. Cadmium-free contact material
