Structural Features: The unit features a modular structure with a front operator panel containing the display and navigation keys. It is designed for control room or panel mounting.

Working Principle: The module receives sensor data (speed, pressure, temperature), processes it using internal PID algorithms, and outputs control signals to actuators (such as steam valves) to maintain the turbine at the desired setpoint.

Installation Requirements:

  • Mount in a control panel with adequate ventilation.
  • Ensure proper grounding to minimize electrical noise.
  • Connect field wiring according to the specific terminal diagram.

Usage Notes:

  • Verify the firmware version matches the application requirements.
  • Do not exceed the maximum voltage ratings.
  • Ensure the operating environment remains within the specified temperature and humidity ranges.
