Why Choose the ABB CR-U012DC2 Pluggable Relay?
The ABB CR-U012DC2 is a robust pluggable universal interface relay designed for electrical isolation, signal interfacing and switching in industrial automation and control systems. As part of the ABB CR-U universal relay series, it operates from a 12 V DC control supply and provides two changeover contacts for flexible control-circuit switching.
This relay provides 2 c/o (SPDT) output contacts rated at 250 V / 10 A. Silver-nickel alloy (AgNi) contacts provide dependable switching performance, while the CR-U construction uses robust circular plug-in pins suited to repetitive industrial use.
Designed to plug into a compatible ABB CR-U socket, the CR-U012DC2 can form a DIN-rail-mounted interface relay assembly for machinery and control cabinets. An integrated blue test button enables manual actuation and locking of the output contacts, simplifying functional testing and commissioning without requiring normal coil energisation.
