Guardmaster Safety Monitoring Relays Wiring Diagrams

This document provides wiring diagrams and application examples for Allen-Bradley Guardmaster single and special function safety monitoring relays, including models MSR5T, MSR22LM, MSR55P, MSR57P, MSR117T, MSR124RT, MSR125HP, MSR126.1R, MSR126T, MSR127RP, MSR127TP, MSR131RTP, MSR138.1DP, MSR142RTP, MatGuard, Safedge, and Sipha controllers. It details input devices (E-stops, limit switches, light curtains, interlock switches, palm buttons, safety mats) and output devices (safety contactors, drives, electronic starters) for various safety categories (2, 3, 4) and performance levels (PL c, d, e), with notes on dual-channel circuits, fault detection, restart interlocks, and control guards.
