Allen-Bradley | 440R-N23132 |Minotaur MSR127TP

Product Description: Allen-Bradley 440R-N23132

The Allen-Bradley 440R-N23132 is part of the Minotaur MSR127TP family of safety relays, designed to monitor dual- channel input devices such as emergency stop buttons, safety interlock switches, and light curtains. This unit provides three redundant normally open safety outputs and one normally closed auxiliary output, offering robust safety logic in a compact and efficient design. The MSR127TP series is widely used in industrial safety systems where redundancy, cross-fault detection, and compliance with global safety standards are critical. The 440R-N23132 supports both automatic and manual reset modes and is DIN rail mountable, allowing quick integration into control panels.
