These non electric digital timers are perfect for applications where electrical timing solutions are to costly or to hazardous. These predetermining timers have 2 sets of windows one on top of the other. You preset the bottom row of digits to represent the number of minutes you wish to time. When you apply the pneumatic start signal, the top set of windows reflect the minutes passed. When the two sets of windows match, a pneumatic output is produced. The Auto rest models produce a momentary output and then reset themselves to "O".
