Key Features

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

• Adopts high‑precision PID control algorithm, with critical‑speed avoidance, valve position limiting and overspeed protection functions

• Rich I/O interfaces: digital contact inputs, 4‑20 mA analog inputs, analog outputs for actuator/valve drive

• Built‑in self‑diagnosis for sensor faults, short‑circuit/open‑circuit detection and alarm output

• Equipped with RS‑232/RS‑485 and Ethernet ports, supports Modbus protocol for DCS/PLC connection

• Rugged industrial‑grade design with strong anti‑EMI and anti‑vibration performance, adaptable to oil‑gas, marine and power‑generation harsh environments
