As an interface, interface relays connect the electronic control level, for example PLC, to the level of sensors/actuators. Here they take over various functions: Switching of direct or alternating current loads with different ohmic, inductive and capacitive proportions, switching in the voltage range from a few mV to 250 V, switching in the current strength range from a few mA to 12 A, amplification of weak control signals, potential separation of control and load circuits as well as signal multiplication. The CR-M series has 13 different coil voltages with 2-4 changeover contacts. You can select an in-built test button for manual operation and locking of the output contacts as well as relay variants with or without built-in LED Two socket versions are available: Standard socket and logical socket. Plug-in function modules such as reverse polarity protection / snubber diode, RC links or surge protection add to the range of applications of this pluggable miniature relay.
