Short DescriptionGUARDMASTER EXPANSION MODULE DELAYED OUTPUTS SAFETY RELAY
Long DescriptionThe ALLEN-BRADLEY 440R-EM4R2D is an expansion module that adds delayed outputs for safety monitoring systems. Designed for use with Guardmaster monitoring safety relays, this EMD provides delayed output functionality while accepting a single-wire safe-only input and offering zero auxiliary outputs. It supports safety control architectures where timed output behavior is required without additional auxiliary contacts. Ideal for machine safety applications that need a compact expansion module to integrate delayed safety outputs into existing Guardmaster relay setups, simplifying retrofits and system expansions.
