Most electronic time delay relays with an off delay function require input voltage to be applied continuously in order to operate correctly. However, there are many applications where this is not possible--keeping a relay energized for some amount of time after input voltage has been removed. A true off delay product provides this function even when input voltage is removed. It duplicates the operation of the older off delay pneumatic time delay relays.

Operation of On Delay/True Off Delay: Upon application of input voltage, a preset delay begins (T1). At the end of the preset delay, the relay is energized. When the input voltage is removed, the relay contacts remain energized for a second, independently adjustable preset time (T2). At the end of the second preset time, the relay is de-energized. Voltage must be applied for a minimum of 0.1 second to assure proper operation. Any application of the input voltage during the time (T2) will keep the relay energized & reset T2. When input voltage is removed, the relay contacts remain energized for the full time (T2). No external trigger switch is required.
