Our 12-24 VAC/VDC digital timer is a reliable and highly accurate simple solution to many complex timing applications. A momentary contact closure begins the timing cycle (15, 30, 45 seconds or ?) and latches a set of Form "C" dry contacts. The compact design makes it versatile for many applications

For example, when used on an egress door, the supervised contacts can be set to either 'Fail Safe' or 'Fail Secure' mode. A built-in reset feature allows the circuit to reset after a single operation or a single door open and close (single passage) before timing expires. This prevents re-entry of any unauthorized personnel.
