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’s 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’s digital governor controls (e.g., 8200-1300) and Peak150 series (e.g., 8200-176), focusing specifically on servo-valve positioning.
