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 16 A, amplification of weak control signals, potential separation of control and load circuits as well as signal multiplication. The CR-P series has 9 different coil voltages with 1-2 changeover contacts. Two socket versions are available: Standard socket and logical socket. Plug-in function modules such as reverse polarity protection / snubber diode, LED module, RC links, overvoltage protection or time modules add to the range of applications on pluggable PCB relays.
