THDS Series
The THDS 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 (Single Shot):
Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch, the output energizes for a measured interval of
time. At the end of the delay, the output de-energizes.
Opening or reclosing the initiate switch during timing
has no affect on the time delay. The output energizes if
the initiate switch is closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.
