GSR safety relays meet global functional-safety standards such as EN ISO 13849-1, and include seven basic units capable of supporting a range of safety devices in single- and multi-zone configurations. It has single-wire communication capability that helps eliminate dual-channel connection between relays. "AND/OR" logic is set via rotary switch on the front of the relay, and a universal input feature allows safety interlock switches, emergency-stop switches and safety mats to use the same set of input terminals.
