Why Choose the ABB CR-M125DC4LD Pluggable Relay?
The ABB CR-M125DC4LD is a compact and reliable pluggable miniature interface relay designed for electrical isolation, signal interfacing and switching in industrial automation and control systems. As part of the ABB CR-M interface relay series, it operates from a 125 V DC control supply and provides four changeover contacts for controlling multiple circuits from a single input signal.
This relay provides 4 c/o (SPDT) output contacts rated at 250 V / 6 A. The CR-M125DC4LD incorporates an integrated LED for visual indication of coil energisation together with a diode for surge suppression, making it particularly suitable for DC-operated industrial control circuits.
Designed to plug into a suitable ABB CR-M socket, the CR-M125DC4LD supports convenient installation and replacement in control cabinets. An integrated test button allows manual actuation and locking of the output contacts during testing and commissioning, while the compact relay body helps conserve valuable panel space.
