The 440R-N23114 MSR126.1T operates as a Monitoring Safety Relay in industrial safety control systems, providing reliable switching logic for safety circuit applications. It continuously processes safety input signals received through either single or dual-channel wiring configurations and converts these into decisive output switching actions via two normally open (N/O) undelayed contacts.
The 440R-N23114 provides essential safety monitoring functions common to the entire protection circuit, and is a critical component of the safety control path, directly affecting the proper, normal operation of the overall safeguarding system. One 440R-N23114 relay is typically required per safety zone depending on the desired input channel configuration. The 440R-N23114 utilizes fixed screw terminals accommodating input wiring from 0.2 to 2.5 mm² and is mounted in a standard control panel position, ensuring secure physical connections.
For Dual-Channel safety applications, the 440R-N23114 supports a dual input channel configuration wired to safety devices such as interlock switches or emergency stop buttons. In addition to standard single-channel operation, the dual-channel configuration also performs automatic cross-monitoring of input states. The 440R-N23114 dual-channel safety circuit executes monitoring using the internal safety logic specified in the relay design.
The 440R-N23114 MSR126.1T Allen-Bradley Monitoring Safety Relay may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
