Guardmaster Safety Relays

Allen Bradley Guardmaster Safety Relays

Guardmaster Safety Relays from Allen Bradley are industrial safety system components. They monitor safety devices like emergency stop buttons and light curtains to detect potential hazards. When a safety device activates, the connected relays swiftly initiate a safety response, such as stopping machinery or activating alarms, to prevent accidents and protect users and equipment. The Guardmaster Safety Relays series includes general-purpose relays and special-purpose relays. Each Guardmaster Safety Relay comes with 4 removable terminal blocks.
