Allen Bradley 440R-GL2S2P Guardmaster Safety Relay – GLP, 24V DC Supply, Dual-Channel Input, 2 N.O. Safety Outputs, 1 N.C. Solid-State Auxiliary

The Allen Bradley 440R-GL2S2P is a Guardmaster Guardlocking Proximity Safety Relay (GLP) designed to monitor safety gate interlocks, guardlocking switches, and proximity-based safety devices. Operating on a 24V DC supply, this compact relay module provides two normally open (N.O.) safety outputs and one normally closed (N.C.) solid-state auxiliary output, offering reliable machine protection in demanding industrial environments.

With dual-channel input evaluation and Performance Level “e” per EN ISO 13849-1, the 440R-GL2S2P ensures fault tolerance and redundancy in safety circuits. Its slim 22.5mm housing allows easy installation on standard DIN rails, while removable plug-in terminals simplify wiring and maintenance. This safety relay is ideal for applications requiring monitoring of guardlocking proximity devices with category 0 stop functionality.
