The Foxboro SRD960 is an intelligent, universal digital valve positioner designed for precise control of pneumatic actuators in industrial process environments. It offers advanced communication capabilities (HART, PROFIBUS PA, FOUNDATION Fieldbus) and a local LCD display with push-button interface for easy configuration and operation. Built for reliability in harsh conditions, it supports both single- and double-acting actuators with excellent linearity and diagnostic features.

• Advanced Communication: HART 4-20 mA, PROFIBUS PA, or FOUNDATION Fieldbus options.
• Easy Setup: Local keypad and LCD for quick autostart configuration (Endpoints, Standard, Enhanced, Smooth/Fast response).
• Robust Design: IP66 / NEMA 4X enclosure, explosion-proof (Ex ia) versions available.
• High Performance: Linearity < 0.4%, hysteresis max. 0.3%, stroke range 8–260 mm, operating angle 0–95°.
• Diagnostics: Auto diagnostics, step response analysis, position/response histograms.
• Flexible Mounting: Multiple adapter options (NAMUR, direct mounting) for linear and rotary actuators.
• SIL 3 Safety Level: Suitable for safety-critical applications.

Ideal for process industries including oil & gas, chemical, power generation, and water treatment. Perfect for control valves in both linear and rotary actuator setups requiring high accuracy, diagnostics, and digital integration.
