The Crouzet 81 series pneumatic adjustable negative time delay module requires operating pressure ranging between 2bar and 8bar. This timer has a counting range from 0.1 seconds to 15 seconds. On the application of a pilot signal, the reservoir starts to fill via the flow restrictor. After the set time delay the relay is operated and an output is given. This timer will not reset until the pilot signal is removed.
