Pneumatic timer, normally open

After the pilot signal is applied at port 10, a preset time elapses before the pneumatic timer is actuated. It returns to its initial position via a return spring once the signal is removed. The time delay is infinitely adjustable by means of a regulating screw. The time delay is reset automatically within 200 ms.
