TDUI / TDUIH / TDUIL SERIES
Description
The TDUI Series combines digital timing circuitry with universal
voltage operation. Voltages of 24 to 240VAC and 12 to 24VDC
are available in three ranges. The TDUI Series offers DIP switch
selectable time delays ranging from 0.1 seconds to 102.3
minutes in three ranges. Its 1A rated output, ability to operate
on multiple voltages, and wide range of switch selectable time
delays make the TDUI Series an excellent choice for process
control systems and OEM equipment.
Operation (Interval)
Upon application of input voltage, the time delay begins. The
output energizes during the time delay. At the end of the time
delay, the output de-energizes and remains de-energized until
input voltage is removed.
