Panel or Subplate Mounted Pneumatic Timer (Up to 3 Minutes)Item # PMT1G1B3

The Type PMT timer is an adjustable precise 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 an output. The timer resets automatically after removal of the control signal.

The PMT has a separate subplate enabling the unit to be supplied with 10-32 or 1/8 NPT porting. The timer can be panel mounted with a bezel, or in the rear on a sub plate.

Low Pressure VersionThe PMT standard control input pressure range is 30 to 100 PSI. For a low pressure pilot actuator (15 PSI min.), change the "B" in the catalog number to "A".
Subplate Mounting PositionStandard timers are supplied with the subplatemounting position at the bottom of the timer. Formounting the subplate in another position, change thelast digit of the catalog number as follows: 1 for top; 2for right side; 3 for bottom; 4 for left side.
Power ConnectionsFor installations requiring larger output valves, use thestandard timer and connect a pneumatically operatedsingle air piloted 3 or 4 way valve of the size required tothe timer output. Contact factory with sizerequirements.
