Why Choose the ABB CR-M012DC4LD Pluggable Relay?
The ABB CR-M012DC4LD is a compact and reliable pluggable miniature interface relay designed for electrical control, industrial automation and interface applications. As part of the ABB CR-M pluggable relay series, it provides four changeover contacts and a 12 V DC control coil for dependable switching between control circuits and connected loads.
This relay features 4 C/O (4PDT) contacts with a contact rating of 250 V / 6 A. Its plug-in construction allows installation in a compatible ABB CR-M socket, simplifying control-panel assembly, servicing and relay replacement without disturbing permanent field wiring.
The CR-M012DC4LD version incorporates an LED status indicator and free-wheeling diode, providing clear visual indication of coil energisation while helping suppress inductive voltage transients in DC control circuits. Its compact construction makes it particularly suitable for PLC interfaces, machinery, process control and general industrial switching applications.

Reliable Switching for Industrial Control Systems
Pluggable interface relays such as the ABB CR-M012DC4LD provide an effective switching interface between low-voltage control equipment and electrical loads. The relay's four changeover contacts allow multiple circuits or signals to be switched simultaneously from a single 12 V DC control input.
The CR-M range is designed for convenient integration into industrial control systems using compatible relay sockets and accessories. On the CR-M012DC4LD, the integrated LED makes coil status easy to identify during commissioning and troubleshooting, while the free-wheeling diode provides suppression of inductive voltage peaks generated when the DC coil is de-energised.
Typical Applications
- Industrial control cabinets and switchboards.
- PLC output and interface circuits.
- Machine control and automation systems.
- Signal isolation and switching circuits.
- Motor control and auxiliary circuits.
