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.
