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.
