EPW2G | Pulse Width (PWM) Input to Pressure Output Interface Module | ACI
EPW2G | Pulse Width (PWM) Input to Pressure Output Interface Module 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 and two LEDs, one to indicate power and one for signal status. 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. Three basic configurations are available: The EPW is a c
