ABB CR-M110DC4L Plug-in Relay Module with 110V DC Coil and Four Normally Open Contacts for Industrial Automation

CR-M110DC4L ABB Plug in relay module Dc coil Four normally open contacts

Product Overview

The ABB CR-M110DC4L is a high-performance plug-in control relay module in the ABB CR-M series, specifically designed for signal isolation, logic expansion and load driving in industrial automation, process control, rail transit and DC control systems. 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 the efficiency of system maintenance. It is equipped with 4 sets of normally open (NO) silver alloy contacts, which have a high electrical life. It is also provided with a green LED indicator light to display the working status of the coil in real time, facilitating on-site debugging and fault diagnosis.

Key features

✅ dc dedicated, stable and reliable

Optimized for 110 V DC control systems, the coil has strong surge resistance and is suitable for PLC output, DCS systems and battery-powered scenarios.
✅ Plug and play, high maintenance efficiency

The relay body is separated from the base. When a fault occurs, there is no need to disconnect the wires. Replacement can be completed within 3 seconds, minimizing downtime to the greatest extent.
✅ high load capacity contacts

The contacts are made of AgNi (silver-nickel alloy) material, which is resistant to electric arcs and oxidation
The rated switching capacity reaches 6 A / 250 V AC (AC-15) or 2 A / 30 V DC (DC-13).
✅ state visualization

It is equipped with a built-in green LED indicator light to visually show whether the coil is powered on, enhancing the maintainability of the system.
✅ flexible installation, complete certification

Compatible with various CR-P series sockets (screw/spring terminals)
Supports 35mm DIN rail mounting
It has passed international certifications such as CE, UL, CSA and CCC, and complies with the IEC/EN 61810-1 standard
