Key Features

• Dual redundant magnetic pickup (MPU) speed inputs, built‑in torsional vibration notch filtering, stable anti‑interference for engine flexible coupling working conditions

• Supports isochronous (zero‑droop) and droop control modes, suitable for standalone operation or grid‑parallel generation

• Accepts 4‑20 mA / 1‑5 VDC analog remote setpoint for speed/load remote adjustment

• Built‑in overspeed shutdown, startup fuel limit, acceleration/deceleration ramp control, torque‑based fuel limiting logic

• Compatible with Woodward DSM/DSLC synchronizer modules to realize real‑power load‑sharing for multiple parallel‑running units

• Rich configurable I/O: 4 analog inputs, 3 analog outputs, 8 discrete inputs, 3 discrete outputs, compatible with electro‑hydraulic actuators, alarm relays and DCS/PLC systems

• RS‑232/RS‑422 communication ports, supports parameter configuration and real‑time monitoring via Woodward Watch Window softwareWoodward

• Industrial‑grade wide‑temperature, anti‑EMI, anti‑vibration and surge‑protection design, Class I hazardous area certification
