Woodward 8200-177 EM/LQ Digital Driver Actuator Control Module

The 8200-177 (Model: 8200-177 Rev T) is a high-performance digital actuator driver designed to interface between Woodward MicroNet™ or NetCon™ control systems and electric actuators or LQ valves. As a specialized EM (Electromechanical) resolver driver, it provides the high-current power amplification and digital signal conditioning required for precise positioning in gas, steam, and hydro turbines. The 8200-177 (Part Number: 8200-177) excels in managing high-bandwidth variable geometry applications where stability under varying load inertia and friction is mission-critical.

Engineered for 24/7 industrial duty, the 8200-177 (Digital Driver: 8200-177) utilizes adaptive control algorithms to maintain sub-millimeter valve positioning accuracy. This Revision T unit is optimized for 24 VDC output, supporting up to 16 A peaks to overcome mechanical stiction in large-scale valves. The driver incorporates galvanic isolation and RS-485 communication, allowing for deep diagnostic integration into modern Distributed Control Systems (DCS) while protecting sensitive control-room electronics from high-voltage field disturbances.
