THDM SeriesTimer - Delay-on-Make
Connection:
Load may be connected to terminal 3 or 1.
RT is used when external adjustment is ordered.
L1 N/L2
The THDM Series is a high power solid-state
delay-on-make timer that is connected in series
with the load. The THDM eliminates the need
for a timer and a separate solid-state relay. A cost
effective approach for controlling larger loads,
such as motors, electric heating elements, and
lamps. When mounted on a metal surface, it can
switch loads up to 20A steady, 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 is energized
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output.

and diagrams.
