The Type PMT timer is a precise adjustable time delay control device. The timer is available with an on delay (NC) output.

Timing operation is dependent upon the input of a separate control signal which starts the timing sequence by setting a vacuum within the timer. Using atmospheric pressure, independent of line pressure, the timer begins the preset timing cycle. At the end of the cycle an internal 3 way valve is switched providing a pilot signal output. The timer resets automatically after removal of the control signal.

The PMT has a sub-plate(ordered separately) enabling the unit to be supplied with 10-32 or 1/8 NPT porting. The timer can be panel mounted with a bezel, or surface mounted on a sub-plate.
