Core Functions

1. Precise Control: Built‑in 5‑channel PID controllers (speed/load PID, cascade PID, 2 auxiliary PID), supporting single‑valve / split‑range dual‑actuator control and extraction/inlet steam decoupling control. Equipped with OptiTune adaptive PID algorithm, speed control accuracy reaches ±0.25%.

2. Safety Protection: 3 critical speed avoidance ranges, overspeed pre‑trip protection, high/low speed & pressure interlock shutdown, reverse rotation detection alarm, complete self‑diagnosis and relay trip outputs.

3. Human‑Machine Interaction: Integrated color graphical panel, multi‑language support including Chinese, local parameter configuration, real‑time monitoring and fault inquiry.

4. Communication: Supports Modbus RTU/TCP, Ethernet and other industrial protocols for data exchange with upper‑level control systems.
