Core Functions

1. Multi‑parameter PID control: speed, load, inlet pressure, exhaust pressure, extraction/admission header pressure regulation。

2. Supports single‑unit isochronous speed control and multi‑unit droop parallel load sharing.

3. Built‑in overspeed protection, zero‑speed detection, startup ramp, load rejection protection and anti‑surge control.

4. On‑panel keypad & display for local configuration, parameter setting and fault diagnosis.

5. Seamless connection with plant DCS/PLC via 4‑20 mA analog signals and Modbus communication。
