Description
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, 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.
