2. Forward‑acting output logic: fuel increases with rising control signal; power‑loss fail‑safe to no‑fuel position, compatible with standard proportional electric‑hydraulic actuators.

3. PID closed‑loop control with startup ramp, actuator stroke limit, load rejection protection and overspeed test function.

4. Supports 4‑20 mA remote setpoint input for speed/load adjustment, compatible with DCS/PLC systems.

5. RS‑485 Modbus‑RTU communication for real‑time monitoring and parameter configuration.
