Description
The TDM Series is a delay-on-make timer that
combines accurate digital circuitry with isolated
DPDT relay contacts in an industry standard 8
pin plug-in package. DIP switch adjustment
allows precise selection of the time delay over
the full time delay range. The TDM Series is the
product of choice for custom control panel and
OEM designers.
Operation
Upon application of input voltage, the time delay
begins. The output is de-energized before and
during the time delay. At the end of the time delay,
the output relay is energized and remains
energized until input voltage is removed.
Reset: Removing input voltage resets the time
delay and output.
