Latching/Timer Module
STI Latching and Timer Modules
The LT-1UL and LT-1 are compact 12-24 VAC/VDC digital timers. A momentary contact closure begins the timing cycle (15, 30 or 45 seconds, or indefinitely) and latches a set of Form C dry contacts, and the LT-1UL is the UL version.
A built-in reset lets the circuit reset after a single operation or a single door open and close (single passage) before timing expires, which prevents re-entry of unauthorized personnel. Pair the module with shielded Stopper Stations, or browse the full STI catalog.
