Allen Bradley 440R / GuardLocking Safety Monitoring Safety Relay, 24V dc, Dual-Channel, 1 Safety Contacts

Allen-Bradley Guardmaster GLP Safety Relay

The Guardmaster GLP safety relay has been developed specifically for guard locking applications, it helps OEMs reduce design and installation time for standstill or slow-speed guard locking applications. Using two proximity sensors as inputs it monitors motion and unlocks a gate when equipment reaches a safe speed.
The GLP safety relay is designed to meet international safety standards, such as EN ISO 13849-1 and EN 62061. It features a patented, single-wire communication capability that helps eliminate the need for dual-channel connection between relays. Safety functions can be expanded and cascaded up to a safety integrity level (SIL) 3 rating using a single wire to connect between relays thus reducing installation time.
