Time Delay Relays
Dedicated - Delay-on-Break
TDUB SERIES
Delay-on-BreakTimer
Description
TheTDUB Series combines digital timing circuitry with universal
voltage operation. Voltages of 24 to 240VAC and 12 to 24VDC
are available in three ranges. TheTDUB 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 theTDUB Series an excellent choice for process
control systems and OEM equipment.
Operation (Delay-on-Break)
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output energizes. The
time delay begins when the initiate switch is opened (trailing
edge triggered). The output remains energized during timing.
At the end of the time delay, the output de-energizes. The output
will energize if the initiate switch is closed when input voltage is
applied.
Reset: Reclosing the initiate switch during timing resets the time
delay. Loss of input voltage resets the time delay and output.
