TDM / TDMH / TDML Series
Delay-on-Make Timer
Description
TheTDM/TDMH/TDML 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.TheTDM/TDMH/TDML series
is the product of choice for custom control panel and OEM
designers.
Operation (Delay-on-Make)
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.
Reset: Removing input voltage resets the time delay and
output.
