CR-M230AC4L ABB Plug in relay module High reliability control relay
Supports quick replacement
Product Overview
The ABB CR-M230AC4L is a high-performance plug-in control relay
module in the ABB CR-M series, specifically designed for signal
amplification, logic control and circuit isolation in industrial
automation, building control and OEM equipment. This product adopts
a modular structure and is used in conjunction with CR-P sockets.
It supports quick plugging and unplugging for replacement,
significantly reducing downtime for maintenance. It is equipped
with 4 sets of normally open (NO) silver alloy contacts, featuring
a high rated load capacity. It is also furnished with LED operating
status indicator lights, facilitating fault diagnosis and system
monitoring.
Key features
✅ Plug and play, high maintenance efficiency
The relay body and the base are designed separately. When a fault
occurs, there is no need to disconnect the wires. Replacement can
be completed within 3 seconds, enhancing the availability of the
equipment.
✅ high electrical performance
Contact material: AgNi (silver-nickel alloy), arc resistant and
wear-resistant
Contact capacity: 6 A / 250 V AC (AC-15), suitable for
inductive/resistive loads such as contactors, solenoid valves,
indicator lights, etc
✅ state visualization
It is equipped with a built-in green LED indicator light to display
the energized status of the coil in real time, facilitating
debugging and troubleshooting.
✅ is flexible to install and highly compatible
Supports multiple socket types (such as CR-P230AC4L, CR-PSS, etc.)
It can be installed on DIN rails (with sockets), saving space in
the control cabinet
✅ is safe and reliable, and fully certified
Complies with the IEC/EN 61810-1 standard
It has passed international certifications such as CE, UL, CSA and
CCC, and is suitable for global projects
