TH1 Series Timer - Delay-on-Make Features:

Timer - Delay-on-Make
TH1 Series
The TH1 Series is a solid-state relay and timer
combined into one compact, easy-to-use control.
This highly reliable device eliminates the need
for a separate solid-state relay. When mounted to
a metal surface, it can switch load currents up to
20A steady state, and 200A inrush.
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 .
