ABB Plug-in Relay Module with 24 V DC Low Voltage Coil and Double Normally Open Contacts for Industrial Automation

CR-M024DC2L ABB Plug in relay module Low voltage DC coil double normally open contacts

Product Overview

ABB CR-M024DC2L is a compact plug-in control relay module in the ABB CR-M series, specifically designed for low-voltage DC control systems. It is widely used in industrial automation, PLC interface expansion, robotics, process control and OEM equipment. This product adopts a modular structure and is used in conjunction with CR-P series sockets. It supports tool-free quick plugging and unplugging replacement, significantly improving maintenance efficiency. It is equipped with 2 sets of normally open (NO) silver alloy contacts and a green LED indicator light, achieving dual functions of load driving and visualization of operating status.

Key features

✅ for 24 V DC, compatible with mainstream control systems

Seamlessly integrated with 24V DC control systems such as PLC, DCS, and sensors, with low coil power consumption and fast response.
✅ Plug and play, maintenance zero downtime

The relay body can be directly pulled out from the base for replacement without disassembling the wiring, significantly reducing the fault recovery time.
✅ high reliability contact design

The contacts are made of AgNi (silver-nickel alloy) material, which is resistant to electric arcs and wear
Supports switching between inductive loads (such as small contactors and solenoid valves) and resistive loads
✅ status is visible in real time

It is equipped with a built-in green LED indicator light to visually display whether the coil is powered on, facilitating on-site debugging and troubleshooting.
✅ compact and flexible, fully certified

The width is only 17.5mm, saving space in the control cabinet
Compatible with screw/spring terminal sockets and supports DIN rail mounting
It has passed international certifications such as CE, UL, CSA and CCC, and complies with the IEC/EN 61810-1 standard
