As an interface, interface relays connect the electronic control level, such as PLC, with the level of the sensors and actuators. They perform various functions including switching of 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 6 A, amplification of weak control signals, potential separation of control and load circuits, and signal multiplication. The CR-S series has five different coil voltage ranges with one changeover contact, available in standard or hard gold-plated versions. Two variants are offered: complete variants or freely selectable bases and plug-in relays.
