Timer - Interval
THD2 Series
The THD2 Series combines accurate timing
circuitry with high power solid-state switching.
It can switch motors, lamps, and heaters directly
without a contactor. You can reduce labor,
component cost, and increase reliability with these
small, easy-to-use, Digi-Power timers.
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output energizes during the time delay. At the end
of the time delay, the output de-energizes and remains
de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and
the output.

Appendix A, pages 156-164 for function descriptions
and diagrams .
