Time Delay Relays Delay-on-Break TDB / TDBH / TDBL SERIES * Relay Output, Delay-on-Break *8-pin models UL listed when used in Time Delay Relay combination with P1011-6 socket only. Description The TDB Series combines accurate digital circuitry with isolated, 10A, DPDT or SPDT contacts in an 8-pin or 11-pin plug-in 8-PIN 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 11-PIN Wiring Diagram 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 8-PIN OCTAL SPDT delay. Loss of input voltage resets the time delay and output.
