Key Features

• Dual control modes: Isochronous (zero droop) for standalone constant-speed operation; droop control for grid parallel and load sharing.

• High accuracy: Speed regulation ±0.25% with adaptive PID tuning; supports 0.5–32,000 Hz speed inputWoodward.

• Flexible I/O: 2 speed inputs (MPU/proximity), 8 analog (4–20 mA), 20 discrete inputs; 2 actuator outputs (4–20 mA/20–200 mA), 8 relay outputsWoodward.

• Integrated protection: Overspeed trip, critical speed avoidance, soft start, valve position limiting, 15 fault shutdown + 15 alarm inputs, first‑out fault memory.

• Communications: RS‑232/RS‑485 (Modbus RTU/ASCII); 4‑port Ethernet (Modbus TCP/OPC); password‑protected parametersWoodward.

• Rugged & certified: IP20 enclosure; SIL2 safety integrity; CE/UL compliant; operates –40 °C to +70 °C.
