Series-PXP100

Supported Applications

The ACI Series PXP100 is an analog to pneumatic output transducer designed to convert an analog electrical input signal into a proportional pneumatic pressure output. The unit automatically modulates its control valves to regulate branch line pressure to a selected set point determined by the input signal, providing a 0 to 100 psig (0-689.5 kPa) modulating output.

Operating Conditions & Performance

The PXP100 operates within an ambient temperature range of 35 to 120°F (1.7 to 48.9°C) and a humidity rating of 10 to 95% non-condensing. Storage is supported from -20 to 150°F (-28.9 to 65.5°C). The device requires an air supply pressure with a maximum of 110 psig (758.4 kPa) and a typical operating range of 102 psig (710.2 kPa) to 106 psig (730.8 kPa).

Performance specifications include an output pressure accuracy of 1% full scale at room temperature and 2% full scale across the operating temperature range. The unit incorporates two valves, does not use air at set point, and features a response time similar to its load rate as it is not limited by any internal restrictor.

Power & Signal Specifications

• Supply Voltage: 24 VAC (+/-10%), 50 or 60Hz, or 24 VDC (+10%/-5%)
• Input Signals (Selectable): 0-5 VDC @ 10,000 Ω; 0-10 VDC @ 10,000 Ω; 0-15 VDC @ 10,000 Ω; or 0-20 mA @ 250 Ω
• Feedback Signal: Factory calibrated 0-5 VDC proportional to output span (Output Pressure)
• Air Consumption: 750 scim (12.29 liters) at supply valves with 100 psig main/95 psig out

Mechanical & Environmental Limits

• Pneumatic Connections: Accepts ¼" OD rigid or semi-rigid metallic tubing using integral compression fitting, ferrule & nut
• Branch Line Volume Requirement: Minimum of four cubic inches (65.54 cc) to operate without oscillation
• Housing Material: Polyvinyl Chloride (PVC)
• Flammability Rating: UL94 V-0
• Dimensions: 3.25" (W) x 2.18" (H) x 1.87" (L) / 82.55 x 55.37 x 47.49 mm
• Weight: 0.47 lbs. (0.2126 Kg)

Configuration Options

The Series PXP100 is configurable for various input signal types and offers specific options to support installation requirements.

• Input Signal Selection: Four selectable ranges (Voltage or Current) convert the electrical input to a 0-100 psig output pressure range. Field calibration is possible upon request.
• Manual Override: A jumper-selectable manual/auto override function allows output variation for setup and troubleshooting, independent of the input signal in MAN mode.
• Failsafe Behavior: If power to the PXP100 is lost, it maintains branch line pressure assuming no leaks exist in the branch line.
• Housing Options: The standard unit features a PVC snap track. An optional 20 Gauge Metal Enclosure (Model ENC1) is available for holding interfaces products.

Installation & Safety Notes

• The main air port should be filtered externally by the customer; warranty does not cover malfunction due to clogged valves or operation without main air supply.
• If 24 VDC power is shared with devices having coils, each coil must have an MOV, DC Transorb, or diode placed across it. For 24 VAC systems sharing coils, use an MOV, AC Transorb, or spike snubbing device.
• Grounding is required before touching the board as some components are static sensitive.

Key Product Differences

The primary variation within this series involves the selectable input signal configuration (0-5 VDC, 0-10 VDC, 0-15 VDC, or 0-20 mA) and the availability of custom calibration. The standard model PXP100 is supplied with a PVC snap track housing; an alternative metal enclosure option exists for specific mounting needs.
