Note
This safety device can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster.
Guardlink simplifies and reduces the connection time of the safety system, whilst providing real-time diagnostic information over Ethernet IP. This makes it simple to identify the location of the device that has tripped the safety system, thus reducing downtime, and improving the machines overall efficiency. For more details, please go to the Guardlink brochure.
