ABB CR-M110DC4 Pluggable Interface Relay

Description

The ABB CR-M110DC4 Pluggable Interface Relay is a specialized component for the electrical and automation sectors, designed for use in automated equipment. As a non-customizable, non-imported unit, it features a base plug-in mounting design for easy installation and replacement. Key technical specifications include a 110 V DC rated control supply voltage, with a pull-in voltage of 88 V and release voltage of 11 V. The relay has a coil rated power of 0.9 W and coil internal resistance of 11000 ohms, with a pull-in time and release time of 25 ms each. It is equipped with 4 changeover (CO) contacts made of silver alloy, supporting an output current of 5 A at 250 V, a rated voltage of 250 V, and contact resistance of 100 milliohms. The relay uses air as its arc extinguishing medium, and has a mechanical lifespan of 10 million operations and an electrical lifespan of 100,000 operations under AC-1 conditions. Its maximum no-load switching capacity is 9000 operations per hour, and it operates reliably in a temperature range of -40 to 70 degrees Celsius.
