Description
The TSDS utilizes a stable oscillator for its time
base and a C/MOS digital predetermined counting
circuit to provide excellent repeat accuracy.
Suitable for many applications including
dispensing, welding, exposure timing--those
applications requiring single shot timing.
Operation
Input voltage must be applied before and during
timing. Upon momentary or maintained closure
of the initiate switch, the output is energized 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 will not energize 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.
