Compact safety relays for applications with mechanical locking switches
The UE44-3SL safety relay protects doors that require a locking device. The relay sends safety signals to unlock a mechanically protected door and unlocks it after a certain amount of time (max. 30 s). If the door closes again, it will lock after a maximum time delay of 30 s, allowing the machine to safely start again. The third safety output, which works contrary to the two classical safety outputs, controls the release and the locking.
