The 8200-226 (Model: 8200-226) is a high-precision Servo Position Controller engineered to drive industrial servo valves and process complex position demand signals. This module serves as a critical interface between electronic governors and hydraulic or pneumatic actuators, specifically designed to replace and upgrade legacy models 8200-224 and 8200-225. By converting low-level control signals into high-current drive outputs, the 8200-226 (Part Number: 8200-226) ensures the exact fuel metering and valve positioning required for stable turbine and engine speed regulation.
Built for the rigors of mission-critical power generation and marine propulsion, the 8200-226 (Model: 8200-226) features an 11-bit resolution for ultra-fine actuator adjustments. It operates on a nominal 24 VDC supply and offers a flexible current range of $\pm$ 10 to $\pm$ 250 mA, making it compatible with a wide array of Woodward proportional actuators, including the 512 and 8256 series. Its digital architecture eliminates the calibration drift associated with analog components, maintaining E-E-A-T (Expertise, Authoritativeness, Trustworthiness) standards in demanding industrial automation environments.
The 8200-226 (Model: 8200-226) is optimized for low-latency servo loops and high thermal efficiency.
