SSAC TDI Series, TDIH Series, TDIL Series Data Sheet
TDI / TDIH / TDIL SeriesTimer - Interval
Connection:
L1 N/L2
Relay contacts are isolated.
The TDI Series is an interval timer that combines
accurate digital circuitry with isolated, 10A rated,
DPDT relay contacts in an 8-pin plug-in package.
The TDI Series features DIP switch selectable time
delays ranging from 0.1 to 10,230 seconds in three
ranges. The TDI Series is the product of choice for
custom control panel and OEM designers.
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output relay is energized during the time delay. At the
end of the time delay, the output de-energizes and remains
de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and
the output.

Appendix A, pages 156-164 for function descriptions
and diagrams.
Appendix B, page 165, Figure 8 for dimensional drawing.
