A simple run on timer that will operate for a set length of time. Very easy to set the run times of 1,2,3,4,5 or 6 Hours by DIP switches. The module features on-board Start & Stop Buttons, plus the facility to connect your own switches via screw terminals. The timer is non-retriggerable, so repeatedly starting the timer will not increase the on-time. The timer can be stopped at any time by pressing the stop button. An LED flashes to indicate the timer is operational.
