Timing Modules
Description
The TDU and KSDU Series are encapsulated solid state 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 fixed from 0.1 s to 10,230 s and does not
include the DIP switch. These series are excellent choices for process control systems and OEM equipment.

Operation
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.
