TDB / TDBH / TDBL Series
Description
The TDB series combines accurate digital circuitry with
isolated, 8 A, DPDT or SPDT contacts in an 8-pin or 11-pin
plug-in package. The TDB series features DIP switch
selectable time delays ranging from 0.1–10,230 seconds in
three ranges. The TDB series is the product of choice for
custom control panel and OEM designers.
Operation (Delay-on-Break)
Input voltage must be applied to the input before and during
timing. Upon closure of the initiate switch, the output relay
is energized. 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.
Wiring Diagram
Reset: Reclosing the initiate switch during timing resets the
time delay. Loss of input voltage resets the time delay and
output.
