Product Description
Woodward 8200-224 Servo Position Controller
Product Overview
- The Woodward 8200-224 is a Servo Position Controller (SPC), designed for precise control of servo-valve actuators in industrial applications such as gas and steam turbines, compressors, and other rotating machinery. This microprocessor-based control unit provides accurate positioning for proportional or integrating servo-valves, ensuring reliable operation in applications requiring precise valve control, such as fuel or steam flow regulation. The 8200-224 interfaces with control systems like Woodward__ 505D or MicroNet platforms and is commonly used in power generation, oil and gas, and industrial processes. It features robust diagnostics, flexible communication options, and a compact design, making it suitable for both new installations and retrofits. The 8200-224 is distinct from Woodward__ digital governor controls (e.g., 8200-1300) and Peak150 series (e.g., 8200-176), focusing specifically on servo-valve positioning.
