As an interface, interface relays connect the electronic control level, for example PLC, with the level of the sensors/actuators. 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 6 A, amplifying weak control signals, potential isolation of control and load circuits and signal multiplication. The CR-S series has 5 different coil voltage ranges with 1 changeover contact, optionally in standard or hard gold-plated design. Two variants are offered: complete variants or freely selectable bases and plug-in relays.
