Description
DescriptionDescription
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.

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
energizes and remains energized until input voltage is
removed.
