DIP switch adjustment allows precise selection of the time delay over the full time delay range. The TDM/TDMH/TDML Series is the product of choice for custom control panel and OEM designers. Operation (Delay-on-Make) **==> picture [17 x 6] intentionally omitted <==** **----- Start of picture text -----**
8-PIN
**----- End of picture text -----**
Upon application of input voltage, the time delay begins. The output is de-energized before and during the time delay. At the end of the time delay, the output relay energizes and remains energized until input voltage is removed. Reset: Removing input voltage resets the time delay and output. ## **Wiring Diagram** **==> picture [202 x 26] intentionally omitted <==** **----- Start of picture text -----**
Relay contacts are isolated.
