ABB CR-M3SS standard socket for 3We CR-M relays content_copy

As an interface, interface relays connect the electronic control level, for example PLC, with the sensor/actuator level. They perform various functions: switching of direct or alternating voltage loads with different ohmic, inductive and capacitive components, switching in the voltage range from a few mV to 250 V, switching in the current range from a few mA to 12 A, amplifying weak control signals, potential isolation of control and load circuits and signal multiplication. The CR-M series has 13 different coil voltages with 2-4 changeover contacts. A built-in test button for manual actuation and locking of the output contacts, as well as relay variants with or without built-in LED can be selected. Two base variants are available: standard base and logical base. Pluggable function modules such as reverse polarity protection / freewheeling diode, RC elements or overvoltage protection expand the areas of application of the pluggable miniature relays.
