ABB CR-M110DC4 CR-M Pluggable Interface Relay
The ABB CR-M110DC4 (Order Number 1SVR405613R8000) is a miniature electromechanical interface relay engineered for switching discrete circuits within industrial control panels. It operates on a 110 V DC control supply voltage and provides 4 changeover (4 CO / 4PDT) contacts for multi-circuit switching from a single control signal.
Contact Configuration and Switching Performance
The relay features silver-nickel (AgNi) contact material, providing reliable electrical conductivity and arc resistance. Each of the 4 changeover contacts is rated for a maximum switching voltage of 250 V AC and a rated current of 6 A. Operating on a monostable switching principle, the relay maintains contact position only while the 110 V DC coil remains energized.
Mechanical Design and Manual Testing
Designed for plug-in mounting into standard ABB CR-M series DIN-rail sockets, the module features flat plug-in terminal connections. It includes an integrated manual test button that allows maintenance personnel to manually actuate and lock the output contacts during system commissioning or diagnostic troubleshooting.
