Description

DescriptionDescription

The THD 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.

OperationOperation

Operation

OperationOperation

Input voltage must be applied before and during
timing. Upon closure of the initiate switch, the output
energizes. The time delay begins when the initiate
switch is opened. The output remains energized
during timing. At the end of the time delay, the output
de-energizes. The output energizes if the initiate switch
is closed when input voltage is applied.

Reset: Reclosing the initiate switch during timing

Reset:Reset:

resets the time delay . Loss of input voltage r esets the
time delay and output.
