The ControlAir 500-ACW is a precision I/P transducer that converts 4–20 mA electrical signals into proportional pneumatic output (3–15 psi). Engineered for reliability and fast response, it supports high flow rates with minimal air consumption. Its rugged NEMA 4X (IP65) enclosure makes it ideal for demanding industrial automation and process control applications.
Common Applications:
- Converting electrical control signals (4–20 mA) into proportional pneumatic pressure (3–15 psi)
- Precision control in pneumatic automation and process systems
- Ideal for control loops in valve manifolds and actuator regulation
Key Features:
- Input: 4–20 mA (180 Ω), output: 3–15 psi (0.2–1 bar)
- High repeatability (< 0.5 % span) and low hysteresis (< 1 % span)
- Flow up to 4.5 scfm (127 Nl/min) at 25 psi
- Fast response (< 0.25 s) with minimal air consumption
- Supply pressure up to 100 psi; accuracy insensitive to supply changes
- Rugged NEMA 4X rated (IP65) enclosure, operates from –30 °C to +60 °C
- Connections: ¼″ NPT pneumatic & ½″ NPT electrical
