Introduction to WOODWARD 5466-409
5466-409 Product Overview
The WOODWARD 5466-409 is a high-reliability speed control motherboard, a key component of the brand’s MicroNet digital control series tailored for industrial turbine and generator systems. It integrates advanced PID control algorithms, high-sensitivity signal processing, and built-in overspeed protection to deliver precise speed regulation for gas/diesel engines, steam turbines, and turbogenerators. Widely applied in power plants, oil & gas fields, and marine propulsion systems, it stabilizes generator speeds in thermal power units, controls compressor rotation rates in oil pipelines, and ensures steady operation of ship engines. Its robust design features military-grade components, optical electrical isolation, and resistance to 200V common-mode voltage, effectively reducing noise interference and adapting to high-vibration industrial environments. Fully compatible with WOODWARD 505E governors, it supports Modbus communication for seamless integration into DCS/PLC systems, enabling remote setpoint adjustment and real-time fault diagnosis to enhance operational reliability.
