Description
The ACI 127209 is a precision electronic-to-pneumatic (E/P) transducer engineered for building automation and HVAC control applications. It accepts a 0–5 VDC input signal and converts it to a proportional 0–15 PSI pneumatic output pressure, making it an ideal interface between electronic control systems and pneumatically actuated HVAC equipment such as dampers, valves, and terminal units.
The dual valve design provides accurate, stable pressure conversion with reliable response across the full signal range. This transducer is well-suited for retrofit and new-construction pneumatic control systems where electronic BAS controllers must communicate with legacy or current pneumatic field devices.
