Product Overview

The Allen-Bradley 440R-N23126 is a Guardmaster MSR127T single-function safety relay manufactured by Rockwell Automation. It operates from a 24V AC/DC power supply and provides three normally-open immediate safety outputs together with one normally-closed auxiliary output. This safety relay supports automatic and manual reset, accepts safety inputs including normally-closed contact arrangements and OSSD devices, and uses fixed screw terminals. Its compact 22.5 mm housing is suitable for DIN-rail installation in industrial electrical control systems. The photographed product is marked 440R-N23126, Series C, with an electrical supply marking of 24V AC/DC, 50/60Hz and 2W. The nameplate also identifies AC-15 250V 5A and DC-13 24V 3A output ratings. Both the supplied packaging and the device nameplate show the same catalog number. Rockwell Automation currently lists this model as active.
