Description
The ACI 127213 is a pneumatic dual valve transducer engineered for building automation and HVAC control applications that require reliable electronic-to-pneumatic signal conversion. Accepting a 0–5 VDC input signal and delivering a proportional 0–15 PSI pneumatic output, this device bridges electronic control systems with pneumatic actuators, dampers, and valves — making it an ideal solution for retrofits and new installations alike.
Key Features
- Input signal: 0–5 VDC
- Output pressure range: 0–15 PSI
- Dual valve design for precise pneumatic signal modulation
- Compatible with standard building automation and DDC control systems
- Suitable for use with pneumatic actuators, dampers, and control valves
- Compact form factor for easy panel or field mounting
Applications
- Commercial HVAC pneumatic control systems
- Electronic-to-pneumatic (E/P) signal conversion
- VAV box and damper actuator control
- Building automation system (BAS) integration
- Pneumatic valve and actuator positioning
