The Schneider Electric Foxboro SRI986 is a high-performance, analog electro-pneumatic valve positioner designed for industrial automation. It converts a standard 4-20 mA analog input signal into a precise pneumatic output to accurately position linear or rotary control valves.
This robust positioner is built for reliability in harsh environments, offering exceptional stability, low air consumption, and easy calibration.
Key Features
- Analog Input: 4-20 mA (standard two-wire loop-powered configuration).
- Pneumatic Output: High flow capacity for fast stroking speeds.
- Versatile Mounting: Compatible with Foxboro, as well as common linear (sliding stem) and rotary (quarter-turn) actuators.
- Low Air Consumption: Reduces operating costs in continuous duty applications.
- Intrinsically Safe Options: Suitable for hazardous area installations (check specific certification for this unit).
- Adjustable Zero & Span: Simple field calibration without special tools.
