The ABB CR-M012DC4LDG (1SVR405618R4400) is a compact and reliable pluggable miniature interface relay designed for industrial automation and control applications. Part of the ABB CR-M relay family, this relay combines high switching performance with integrated LED status indication, diode protection and gold-plated contacts for enhanced contact reliability.
Designed to plug into compatible ABB CR-M sockets, the CR-M012DC4LDG provides a space-saving relay solution that can be mounted on DIN rails when combined with the appropriate socket. Its compact construction makes it ideal for control panels where reliable switching and easy maintenance are required.
With a 12 V DC coil supply and 4 changeover (4 C/O or SPDT) contacts, this interface relay supports switching applications up to 250 V AC / 6 A. The integrated LED provides visual confirmation of coil energisation, while the diode helps protect connected control circuits.
The ABB CR-M012DC4LDG provides dependable signal switching for automation and electrical control systems. Its multiple changeover contacts allow one control signal to operate several circuits, making it suitable for complex machine control and interface applications.
The combination of LED indication, diode protection and gold-plated contacts improves operational visibility and long-term reliability, especially in applications where precise switching of small signals and loads is required.
