1SVR405618R1100 ABB CR-M024DC4LG Pluggable Relay 4 C/O 24 V DC

Why Choose the ABB CR-M024DC4LG Pluggable Relay?

The ABB CR-M024DC4LG is a compact and reliable pluggable miniature interface relay designed for industrial automation, control-panel interfacing and signal switching applications. As part of the ABB CR-M pluggable relay series, it combines a 24 V DC control coil with four changeover contacts and gold-plated contact surfaces for dependable switching.

This relay provides 4 C/O (4PDT) contacts rated at 250 V / 6 A. The contacts use a silver-nickel alloy with gold plating (AgNi/Au), improving contact reliability particularly when switching small currents and low electrical loads. Its plug-in construction allows installation in a suitable ABB CR-M socket for straightforward assembly and replacement.

The CR-M024DC4LG also incorporates an integrated LED status indicator for visual indication of coil energisation and a test button for manual actuation and locking of the output contacts. When combined with a compatible socket, the relay assembly can be snap-mounted onto a DIN rail, making it well suited to compact industrial control cabinets.

Reliable Switching for Industrial Control Systems

Pluggable interface relays such as the ABB CR-M024DC4LG provide a practical switching interface between electronic control equipment and field circuits. Its four changeover contacts allow multiple electrical circuits to be switched from a single 24 V DC control signal, making the relay suitable for PLC interfacing, machine control and general automation duties.

The gold-plated contacts are particularly beneficial where small currents or low electrical loads need to be switched reliably. The integrated LED provides immediate visual indication of coil energisation, while the locking test button supports convenient testing and commissioning without requiring the control circuit to energise the relay coil.

Typical Applications

• PLC input and output interface circuits.
• Industrial control cabinets and switchboards.
• Machine control and factory automation systems.
• Low-current signal switching applications.
• Sensor and actuator interface circuits.
• Process control and instrumentation systems.
• Motor control and auxiliary circuits.
