Description

The TDI series is an interval timer that combines accurate

digital circuitry with isolated, 8 A 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.
