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.

Reset: Removing input voltage resets the time delay and

the output.
