Product Description
The Allen-Bradley MSR131RTP is a single-function monitoring safety relay from the Guardmaster Minotaur series, designed to monitor emergency-stop circuits, light curtains, safety mats, and safety gates. It accepts four different input wiring configurations — one N.C., two N.C., two PNP OSSD connections from a light curtain, or a four-wire safety mat — and provides three normally open safety-rated outputs, two normally closed auxiliary outputs, and two PNP solid-state outputs. The relay supports automatic/manual reset or monitored manual reset and achieves the highest safety ratings of Category 4 per ISO 13849-1 (Performance Level e) and SIL 3 per IEC 61508. Cross-fault detection is included for enhanced system integrity.
