440R-S12R2 Applications

This Guardmaster single-input safety relay monitors a dual-channel safety device such as an emergency stop, interlocked gate, magnetic switch or safety sensor. It provides one universal dual-channel input, two undelayed normally open safety output contacts and one solid-state auxiliary signalling output, operating from a 24V DC supply. Rated for use up to Category 4, Performance Level e and SIL 3 with a high MTTFd and 99% safe failure fraction, it uses screw-terminal connectors in a compact DIN-rail housing with IP40 protection. It de-energises the safety outputs to stop hazardous machine motion when the monitored safety circuit opens.
