Description
The TDS series combines accurate digital circuitry with
isolated, 8 A rated, DPDT or SPDT relay contacts in an 8-pin
or 11-pin plug-in package. The TDS series features DIP
switch selectable time delays ranging from 0.1s to 10,230 s
in three ranges. The TDS series is the product of choice for
custom control panel and OEM designers.
Operation (Single Shot)
Input voltage must be applied to the input before and during
timing. Upon momentary or maintained closure of the initiate
switch (leading edge triggered), the output relay 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 will
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.
