Sequential Timer

A sequential timer, also referred to as a sequencer or sequence timer, will energize and de-energize multiple outputs over a period of time. The amount of time before each output is energized and the amount of time the output remains energized is variable. The outputs may be energized one at a time in order. For mechanical relay applications, the relay contacts of the first relay will close. Then, after a set amount of time, the first relay’s contacts will open and the second relay’s contacts will close.
