Allen-Bradley® Guardmaster® Safety Relays from Rockwell Automation check and monitor a safety system and either allow the machine to start or execute commands to stop the machine or control safety-related functions.

Single-function safety relays are the most economical solution for smaller machines where a dedicated logic device is needed to complete the safety function.

Modular and configurable safety relays are preferred where a large and diverse number of safeguarding devices and minimal zone control are required.
