Product Overview
The FOXBORO SRI986-BIDS6ZZZNA is a high-performance electro-pneumatic valve positioner engineered for precise control of pneumatically actuated control valves in demanding industrial process environments. As part of the Foxboro SRI986 series, this instrument converts a standard electrical input signal (typically 4–20 mA) into a proportional pneumatic output pressure, driving the valve actuator to a position that precisely matches the commanded setpoint. The SRI986-BIDS6ZZZNA features a robust, field-proven design with advanced feedback sensing and a high-capacity pneumatic relay, delivering fast response, excellent repeatability, and minimal steady-state air consumption. It is a critical automation component in closed-loop process control architectures, ensuring accurate flow, pressure, level, and temperature regulation across a wide range of industrial applications.
