7022PD

The 7022PD is a panel-mount Electropneumatic Timing Relay with DPDT contact configuration and screw terminals. The 2-1423164-2 timing head circulates air through a variable length to provide linearly adjustable timing. Patented design provides easy adjustment and long service life under severe operating conditions. Off-delay models the switch transfers the load immediately upon energization and the delay period does not begin until the unit is de-energized. At the end of the delay period the switch returns to its original position. Re-energizing the unit during the delay period immediately resets the timing, readying it for another full delay period on de-energization. No power is required during the timing period, providing a true off delay. Oversize adjustment knobs, serrated with high-resolution markings visible from all angles makes the timer easy to set timers.
