The PXP100 is an electric to pneumatic transducer which converts an analog electrical input signal to a proportional pneumatic output. The PXP100 will automatically modulate its control valve(s) to regulate the branch line pressure to the selected set point as determined by the input signal. The PXP100 offers four selectable input ranges which convert to a 0 to 100 psig modulating output. A 0-5 VDC feedback signal indicating the resultant branch line pressure is also provided. This signal varies linearly with branch pressure (0 volts= 0 psig, 5 volts = 100 psig). The PXP100 incorporates two valves and does not use air at set point. It’s branch exhaust lfow and response time are not limited by an internal restrictor and are similar to its load rate. If power fails to the PXP100, branch line pressure remains constant if the branch line does not leak air. The PXP100 accepts ¼” OD rigid or semi-rigid metallic tubing using integral compression fitting, ferrule and nut. A manual override (jumper selectable), which controls the output pressure, is provided for setup and troubleshooting. Custom calibration is available upon request for an additional charge. This will speed up installation time for the end user. Applications: Three-Way Mixing Valve Control, Pilot Positioner Control, Pneumatic Valve & Damper Actuator Control, Fan Vane Control, DDC Control, Above Ceiling Applications (mixing and VAV boxes) The PXP is covered by ACI's Two (2) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's website, www.workaci.com.
