Introducing GuardLink 2.0

Allen-Bradley’s new GuardLink 2.0 is the world’s most advanced serially connected safety input solution, designed to reduce downtime and installation costs. The GuardLink 2.0 protocol also enables safety-rated control device status and automatic diagnostic reporting to a Human Machine Interface using CIP Safety™ over EtherNet/IP.

The new GuardLink 432ES on-machine interface module can connect up to 96 safety devices across three independent safety channels. The 432ES supports linear, star and device level ring topologies while meeting the highest safety rating up to SIL3, CAT 4 PLe.

Each device feeds information about its status back to the controller, allowing for faster fault-finding and prevention of unnecessary downtime. This not only increases the diagnostic capabilities of the entire safety system, but also reduces installation costs.

GuardLink 2.0 from Allen-Bradley brings all the benefits of CIP safety into manufacturing, packaging and processing environments.
