The ALLEN-BRADLEY 440R-D22S2 is a monitoring safety relay that provides guarded safety control for machinery and automation systems. Designed as a Guardmaster safety relay with dual input channels and SS output configuration, it accepts two dual-channel universal inputs to monitor multiple safety devices and consolidates signals for dependable safety logic. A single normally closed solid-state auxiliary output offers reliable status signaling to downstream equipment or indicators. This safety relay is intended for integration into industrial control panels and safety circuits where monitored dual-input protection and a solid-state auxiliary interface are required by machine safety applications.
