Woodward 8280-423 Digital speed controller
The 8280-423 is a model in the 723PLUS family optimized for specific needs. Its core functions include:
Speed Control and Load Sharing: Precisely controls the speed of both engines and achieves mechanical load sharing between them, ensuring balanced power output.
Designed for Medium- and High-Speed Engines: Algorithms are specifically optimized for medium- and high-speed reciprocating engines (such as diesel, natural gas, or dual-fuel engines) with speeds above 100 rpm.
Low-Voltage Operation: Rated operating voltage is 18–40 Vdc (commonly used in 24V systems), requiring a significant current surge during startup.
Flexible Coupling Filtering: Features torsional vibration filtering to handle speed fluctuations in systems with flexible couplings, improving control stability.
Fuel Limiting and Protection: Built-in multiple fuel limiting functions (such as starting fuel limiting, intake manifold pressure limiting, etc.) prevent engine overload or excessive emissions during transient processes.
Programmable I/O: Equipped with configurable discrete inputs and alarm outputs, supporting remote speed setting, clutch status monitoring, etc.

This model is primarily used in marine propulsion systems and industrial power applications:
Dual-engine parallel propulsion systems: Used in situations where two engines jointly drive a propulsion system (e.g., driving a propeller via a parallel reduction gearbox), ensuring synchronized operation and even load distribution between the two units.
Marine propulsion control: Its internal software is pre-programmed for marine propulsion characteristics, handling speed and load fluctuations during clutch engagement/disengagement.
Reciprocating engine control: Suitable for various high-power reciprocating engines, providing higher control precision and network communication capabilities than traditional mechanical governors.
System upgrades and retrofits: Since some models in the 723PLUS series are currently discontinued or undergoing maintenance (replaced by new modules such as LECM), this model is often used as a spare part for existing equipment or as the core for digital upgrades of older systems.
