Allen-Bradley 440R-W23219 GuardMaster Safety Relay

Allen-Bradley 440R-W23219 GuardMaster MSR310P Safety Relay is the base module of the GuardMaster MSR300 family (Minotaur), a 24 V DC powered safety relay that forms the foundation of a configurable safety circuit. The base itself has no built-in safety inputs or safety outputs (Inputs: 0; Safety outputs: 0) and includes three normally open auxiliary outputs (3 NO) to support auxiliary signaling. It requires additional input modules and safety interfaces from the MSR300 lineup to monitor protective devices and drive the machine-control outputs when safety conditions are met. Catalogued as a Stop Category 0 relay, the MSR310P base is designed for straightforward, modular safety configurations and clean integration within a GuardMaster safety system. When paired with other MSR300 components, this base enables tailored safety circuits for guarding applications while operating from a 24 V DC control supply.
