ABB CR-M125DC4L Pluggable Interface Relay

Description

The ABB CR-M125DC4L Pluggable Interface Relay is a compact, versatile component designed for industrial automation applications. Key technical specifications include a 125V DC coil voltage, 24V DC power supply voltage, and 4CO (SPDT) contact configuration. It delivers a 6A load capacity and supports a 24V DC switching voltage, making it suitable for low-power control circuits.

This relay features electrical isolation, enabling energy transfer between circuits without direct electrical contact to enhance user safety in high-voltage environments. Its pluggable design allows for quick, tool-free installation by sliding into compatible ABB CR-M series sockets, and its compact dimensions of 21.2mm (width) x 35.6mm (height) x 27.5mm (length) make it ideal for tight installation spaces. Weighing only 33g, it minimizes mechanical stress on mounting equipment.

Equipped with an integrated test button for fast circuit verification, the CR-M125DC4L supports electrical isolation, signal amplification, and signal matching between electronic controls such as PLCs, iPCs, or field bus systems and sensor/actuator levels. A gold contact version is available for switching sensitive signals, and complete system packages including relays, sockets, holders, markers, and function modules are offered for streamlined setup. The broader CR-M series includes 13 coil voltage options to suit global industrial applications.
