The ALLEN-BRADLEY 440R-GL2S2T is a safety relay designed for guardlocking applications that provides monitored time functions and two solid-state outputs. It combines a compact 22.5mm width package with time monitoring features to control access guards and safety interlocks while tracking dwell and response intervals. The solid-state outputs offer contactless switching suited for frequent operation, and the guardlocking function helps maintain a defined safe state until conditions are met. Ideal for machine safety panels and production line guarding, this relay is intended for engineers and maintenance teams implementing controlled access and time-monitored safety interlocks.
