The ALLEN-BRADLEY 440R-S13R2 is a monitoring safety relay designed to supervise safety circuits and provide reliable auxiliary output control. This Guardmaster single-input relay accepts a dual-channel universal input for versatile connection of safety devices and includes one normally closed auxiliary output for signaling or interlock functions. Its compatibility with legacy control systems makes it suitable for retrofit projects where existing safety wiring must be maintained. Use it to monitor emergency stops, safety gates, or light curtains and integrate with control panels requiring CI-style safety relays; ideal for maintenance teams and integrators updating machine safety without full rewiring.
