Sign in to view price

The ALLEN-BRADLEY 440R-D22R2 is a monitoring safety relay that provides dual input supervision for machinery safety circuits. Designed as a Guardmaster safety relay, it accepts two dual-channel universal inputs for flexible connection to safety sensors and switches, while the dual input (DI) architecture helps monitor redundant safety paths. It includes one normally-closed solid state auxiliary output for signaling control systems or interlocks. This relay is suited for industrial safety applications where reliable monitoring of emergency stops, light curtains, or safety gates is needed, and is intended for integration into machine safety control panels by maintenance and safety engineers.
