Allen-Bradley Guardmaster GuardLink safety system

Rockwell Automation has introduced a safety-based communications protocol known as the Allen-Bradley Guardmaster GuardLink safety system.



Traditionally, safety devices are wired to separate safety inputs, which requires significantly more wiring and introduces more potential fault points. When wired in this series connection, users lose the ability to distinguish information from each device.

With GuardLink, safety devices are easily connected in series while providing access to individual device diagnostics. This system provides safety, diagnostics, remote reset and lock command over a single four-conductor cable with up to 32 devices per link. In addition, installation costs are said to be reduced, with an up to 38% reduction in wiring when using GuardLink.

The GuardLink technology seamlessly integrates with Allen-Bradley Guardmaster safety relays and components, allowing users to access status information throughout their entire safety system. The connection of safety devices with smart taps enabled by GuardLink technology and standard cabling to a Guardmaster safety relay allows greater visibility into the system, down to individual guard doors and E-stops.

The GuardLink safety system fully integrates with the Logix platform with predetermined tag names in the Rockwell Software Studio 5000 application. Its simplified design and reduction in wires allows for simple plug-and-play installation.
