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.

Reset: Reclosing the initiate switch during timing resets the

time delay. Loss of input voltage resets the time delay and

output.
