ABB CR-M Interface Relay 24V dc, 4CO (SPDT) DIN Rail

As an interface, interface relays connect the electronic control level, such as PLCs, with the level of sensors and actuators. They perform various functions: switching DC or AC loads with different resistive, 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, providing potential separation between control and load circuits, and signal multiplication. The CR-M series offers 13 different coil voltages with 2-4 changeover contacts. A built-in test button for manual operation and locking of the output contacts, as well as relay variants with or without built-in LEDs, can be selected. Two socket variants are available: standard socket and logical socket. Plug-in function modules such as reverse polarity protection, flyback diode, RC circuits, or surge protection expand the application areas of the plug-in miniature relays.
