Key Features

• Dual‑MPU redundant speed sensing (2 magnetic pickup inputs), anti‑torsional vibration notch filtering for marine flexible coupling conditions

• Supports isochronous (zero‑droop) and droop control, compatible with DSLC synchronizers for multi‑unit parallel real‑power load‑sharing

• Built‑in marine‑grade protection: overspeed shutdown, lube oil pressure/water pressure monitoring, manifold pressure fuel limit, startup fuel limit, soft load transfer

• Multi‑port communication: RS‑232/RS‑422/LON network, supports Watch Window software configuration, real‑time monitoring and data logging

• Abundant configurable I/O: actuator drive output, analog inputs/outputs, multi‑channel relay alarm/shutdown/status contacts

• Marine‑certified industrial‑grade design: wide temperature, anti‑EMI, anti‑vibration, salt‑fog corrosion resistance for harsh marine/offshore environments

• Perfect matching with Woodward synchronizers, 2301/505 series controls, electro‑hydraulic actuators and DCS/PLC systems
