Emergency stop shutdown to SIL 3 or PL e with contactors with F-PLC-IN and fail-safe controller

Operating principle

The fail-safe controller monitors the emergency stop device.

When the emergency stop device is actuated, the fail-safe controller switches the power contactors off by means of its fail-safe inputs (F-PLC-IN) in a safety-related way.

If the emergency stop device is unlatched and the feedback circuit is closed, the Start button can be used to switch on again.
