FAQ

Q1: What type of control mechanism does the 43AP-FA42CPC use?
It uses Foxboro’s force-balance pneumatic mechanism to ensure stable, accurate, and reliable process control.

Q2: Does this controller support PID?
Yes. It includes proportional, integral (reset), derivative, and differential gap functions for full PID control.

Q3: What is the standard pneumatic output signal?
The controller provides a 3–15 psi (20–100 kPa) pneumatic output with a gauge reading up to 30 psi (200 kPa).

Q4: Can the controller perform bumpless auto/manual switching?
Yes. The internal two-position switch enables smooth transitions without disturbing the process.

Q5: Is this model suitable for harsh industrial environments?
Yes. The rugged NEMA 3 enclosure protects it from dust, moisture, and other field conditions.
