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.

Overview

Offers a broad range of safety functions
Provides versatility through simple logic, reset and timing configurations
Includes single wire safety relay connection which allows for ease of installation and system flexibility
Terminals are grouped together by power inputs and outputs for clear connection
Offers compact solution which saves energy and space on DIN rail
Provides consistent terminal layouts and configuration allow simplified installation
Offers an optional Guardmaster EtherNet/IP Network Interface (440R-ENETR) that allows Guardmaster Safety Relays to communicate on an EtherNet/IP network
Includes the Guardmaster Dual GuardLink safety relay, which provides visibility of system status down to the individual guard doors and E-stops when used with GuardLink-enabled smart safety devices
