Guardmaster Safety Relays

Our Guardmaster® single-function safety relays are designed to meet functional safety standards, such as ISO 13849-1 or IEC 62061, and they offer key functions to simplify installation and system complexity. In addition, information gathered from the GSR intelligent safety relays via the optional EtherNet/IP Interface helps minimize unplanned downtime, increase efficiencies, and enable The Connected Enterprise. The Guardmaster Dual GuardLink Safety Relay further extends this capability to even share diagnostics and status information of safety switches and safety sensors connected in series via GuardLink
