TDM / TDMH / TDML SeriesTimer - Delay-on-Make
Connection:
L1 N/L2
Relay contacts are isolated.
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 (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.
For more information see:
Appendix A, pages 156-164 for function descriptions
and diagrams.
Appendix B, page 165, Figure 8 for dimensional drawing.
