Timer - Delay-on-Break
TDB / TDBH / TDBL Series
The TDB Series combines accurate digital circuitry
with isolated, 10A, DPDT or SPDT contacts in an 8
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.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output .
