ABB Plug-in module pluggable CR-U 41B 1 pc(s)

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 10 A, amplification of weak control signals, potential separation of control and load circuits as well as signal multiplication. The CR-U series has 12 different coil voltages with 2-3 changeover contacts. The built-in test button can be removed to manually operate and lock the output contacts. You can order relays with or without integrated LED. Two socket versions are available: Standard socket and logical socket. Plug-in function modules such as reverse polarity protection / snubber diode, LED module, RC snubber, overvoltage protection or multifunctional timer modules add to the use of this plug-in universal relay.
