SIRIUS Safety Integrated: Protective door monitoring to SIL 3 or PL e with a safety relay

  • Entry
  • Associated product(s)

 

Task

Protective doors are frequently used to fence off danger zones. These are monitored for position and, if necessary, the area from which the hazard emanates is switched off.

Solution

The position of a protective door is monitored via two safety switches. When the monitored door is opened, the safety relay triggers and opens the enabling circuits, switching off the power contactors in a safety-related manner. If the door is closed and the feedback circuit is closed, the Start button can be used to switch on again.
