Pulse Width Modulate (PWM) Input EPW

The EPW* converts a pulse, phase cut, or digital PWM signal into a proportional pneumatic signal ranging from 0 to 20 psig. The pneumatic output is proportional to the signal input, either direct or reverse acting. The EPW* has a manual override potentiometer to vary the pneumatic output.  The EPW* offers four jumper selectable input timing ranges. Output pressure ranges are jumper shunt selectable for 0 to 10, 0 to 15 and 0 to 20 psig, and adjustable in all ranges. A 0-5 VDC feedback signal indicating the resultant branch line pressure, is also provided. This signal varies linearly with the branch pressure range selected. EPW* is designed with electrical terminals on one end and pneumatic connections on the other, allowing for maximum convenience in wiring and tubing installation when panel mounted.  The EPD is covered by ACI's Two (2) Year Limited Warranty.
