ABB pluggable interface relays of the CR-U range are used for electrical isolation, amplification and signal matching between the electronic controlling, e.g. PLC, iPC or field bus systems and the sensor / actuator level. The CR-U range offers up to 3 contacts in one relay and a built in test button which makes a circuit check fast and easy. 12 different coil voltages are available to suit world wide applications. Main benefits include 3 contacts in one relay reduce wiring time; Manual test button reduce testing time; Customizable with pluggable function modules. Main features include 12 different coil voltages 12-220 V DC / 24-230 V AC; 2 c/o contacts (10 A), 3 c/o contacts (10 A); With or without integrated LED; Integrated test button for manual actuation and locking of the output contacts; Logic and standard sockets & Pluggable function modules such as RC elements and varistors available.
