SSAC KSDU Series, TDU Series Data Sheet
KSDU/ TDU SeriesTimer - Delay-on-Make
Connection:
L1 N/L2
The TDU and KSDU Series are encapsulated solidstate, delay-on-make timers that combine digital
timing circuitry with universal voltage operation.
The TDU offers DIP switch adjustment allowing
accurate selection of the time delay over the full
time delay range. The KSDU is factory xed from
0.1s to 10,230s and does not include the DIP switch.
These series are excellent choices for process
control systems and OEM equipment.
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 energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output.

Appendix A, pages 156-164 for function descriptions
and diagrams.
Appendix B, page 165, Figure 1 for dimensional drawing.
