Input signal range: 3 ~ 15 psi

Output signal range: 3 ~ 15 psi

Control accuracy: ±0.5% full scale

Repeatability: ±0.2% of span

Working ambient temperature: -20℃ ~ +65℃

Humidity: 5% to 95%, non-condensing

Housing: heavy-duty metal corrosion resistant shell

The FOXBORO 130FB-N4-A pneumatic controller supports bumpless auto-manual switching. It adopts pure mechanical pneumatic structure without electronic components, delivering excellent anti-interference capability for hazardous industrial environments. Operators can adjust setpoint directly on the local indicator for convenient on-site tuning. This unit is suitable for new plant construction and spare parts replacement of legacy pneumatic control systems. Its robust mechanical design ensures long service life and simple maintenance for process automation.
