Product Description

The 8405-009 is a high-performance actuator processor module developed by Woodward for the ProAct 75 Electric Actuator Series. This module functions as the intelligent control core of electric actuator systems, translating digital control signals into precise mechanical positioning for fuel racks, butterfly valves, and other flow control mechanisms used in turbines and industrial engines.

By processing speed and load control signals in real time, the 8405-009 enables high-accuracy combustion optimization and stable mechanical drive response. It is commonly deployed in modernized turbine and engine control systems where electric actuation replaces hydraulic control mechanisms.

Designed for industrial durability, the module supports fast load transient response and maintains stable operation across a wide range of electrical and environmental conditions.
