THD1 SeriesTimer - Delay-on-Make
Connection:
S1 = Optional Low Current Initiate
Switch
RT is used when external adjustment
is ordered.
L1 N/L2
The THD1 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 (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output.

Appendix A, pages 156-164 for function descriptions
and diagrams.
Appendix B, page 165, Figure 4 for dimensional drawing.
