Key Features

• Digital microprocessor control with single‑valve turbine‑specific control logic for precise speed regulation and stable load control

• Pin‑to‑pin compatible with 2301A series, supporting direct replacement without complex wiring modification

• Supports isochronous (zero‑droop) and droop control modes for standalone constant‑speed operation or multi‑unit parallel load sharing

• Integrated overspeed protection, valve‑position limit, startup/shutdown logic, self‑diagnosis and fault alarm outputs

• Accepts magnetic pickup (MPU) speed signal input, capable of directly driving electro‑hydraulic actuators

• Industrial‑grade wide‑temperature, anti‑EMI and anti‑vibration design, suitable for power plants, chemical plants and waste‑heat utilization harsh environments

• Works compatibly with Woodward 505/2301 series governor systems for local operation and human‑machine interaction
