Product Description

The 8200-177 (Part Number: 8200-177 Rev T) is a high-performance digital driver designed to bridge the gap between Woodward MicroNet™ or NetCon™ control systems and electromechanical (EM) actuators or LQ valves. As a specialized resolver-based driver, it provides the essential high-current power amplification and digital signal conditioning required for sub-millimeter positioning accuracy in gas, steam, and hydro turbine applications.

Engineered for 24/7 industrial duty, the 8200-177 (8200-177) utilizes adaptive control algorithms to manage high-bandwidth variable geometry applications. This Revision T module is optimized for high-torque demands, supporting up to 16 A peak currents to overcome mechanical stiction in large-scale valves. With integrated 1000 Vrms galvanic isolation and Modbus RTU support via RS-485, the 8200-177 (Model: 8200-177) ensures that field-side disturbances do not compromise the integrity of the central processing unit while providing deep diagnostic visibility into actuator health.
