WOODWARD 723 PLUS Digital Governor Controller

WOODWARD 723 PLUS is a high-performance digital governor controller for reciprocating diesel and gas engines in marine propulsion and power generation applications. This digital governor controller delivers precise closed-loop speed regulation and dual-engine load sharing functions. The digital governor controller supports clutch control, speed matching and soft loading for twin-engine combined propulsion systems. The digital governor controller receives magnetic pickup speed signals and outputs actuator drive commands to adjust engine fuel rack.

Engine speed governing is the core function of WOODWARD 723 PLUS. Engine speed governing compares actual engine rotational speed against set reference and adjusts fuel supply dynamically. Reliable Engine speed governing suppresses speed deviation during load changes for stable engine operation. Configurable Engine speed governing supports isochronous and droop control modes for marine and generator use cases.

This unit provides advanced twin-engine load sharing for combined mechanical drive systems. twin-engine load sharing synchronizes fuel rack position to evenly distribute load between two coupled engines. Robust twin-engine load sharing prevents one engine from taking excessive load during vessel maneuvering. Complete twin-engine load sharing optimizes fuel consumption and protects engine mechanical components.

WOODWARD 723 PLUS is equipped with built-in fault monitoring, LED alarm indicators and serial communication for parameter setup and diagnostics. It features torsional vibration filtering, start fuel limiting and torque limiting logic to safeguard prime movers. It accepts 4–20mA remote speed setpoint and rack feedback signals. Widely used for marine main propulsion engines, generator sets and gas compression equipment. It is a trusted digital governor spare part for twin-engine marine propulsion automation systems.
