ABB CR-M125DC4L CR-M Interface Relay
The ABB CR-M125DC4L (Order Code: 1SVR405613R8300) is a pluggable miniature interface relay from ABB's CR-M series designed for signal isolation and circuit switching in industrial control applications. Operating on a 125 V DC coil control voltage, it provides 4 changeover contacts (4 C/O, SPDT) rated at 250 V / 6 A. The relay incorporates an integrated LED coil status indicator and a manual test button for field commissioning and contact locking.
Contact Ratings and Load Capabilities
Equipped with silver-nickel (AgNi) contacts, the relay handles switching loads across various utilization categories:
- AC-12 (Resistive AC): 6 A at 230 V
- AC-15 (Inductive AC): 1.5 A at 120 V, 1 A at 230 V
- DC-12 (Resistive DC): 6 A at 24 V
- DC-13 (Inductive DC): 2 A at 24 V, 0.1 A at 250 V
Physical Architecture and Socket Mounting
The relay features flat-pin plug-in connections and an IP40 protection rating. Measuring 21.2 mm x 35.6 mm x 27.5 mm with a net weight of 0.033 kg, it plugs into compatible ABB CR-M sockets for DIN rail mounting in compact control panels.
