Rockwell Automation safety relays

Rockwell Automation is introducing a new generation of safety relays that will be designed to address the majority of safety-related applications. Existing Allen-Bradley Guardmaster safety relays will not become obsolete, but customers who wish to simplify their inventory and usage will have the choice of a smaller family of safety relays.

This much smaller family of relays can support a broad range of safety devices for a variety of applications. The universal input feature allows devices such as safety-interlock switches, emergency-stop switches, pressure-sensitive mats and OSSD devices, such as safety light curtains, to use the same set of terminals. This removes the requirement for a specific safety relay for a specific type of input device.

Simple logic tasks can also be achieved via the single wire safety connection between relay, removing the need for dual-channel connection while offering SIL 3, PLe safety rating. With this logic functionality, applications can be configured to offer flexible ‘AND/OR’ functional control. Other options can be configured for requirements such as regional and global e-stop functions.

The six safety relays available are:
