Description

The TDM/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. The TDM/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.
