Technical Specifications 24VDC power supply, proportional current output, LVDT excitation and feedback input. Operating temperature: -40℃ ~ +70℃, built-in short-circuit protection for drive loop.
Functional Features Regulation command conversion, proportional drive output, LVDT feedback sampling, valve position closed-loop adjustment, drive fault alarm.
Application Scenarios Gas engine fuel actuator control, steam turbine governing valve closed-loop drive loops.
Performance Parameters High drive linearity, precise position holding, fast response to command changes.
Structural Characteristics Heavy-duty rack pluggable drive module, drive running and fault LED indicators.
Working Principle The module compares target valve opening command with real-time LVDT feedback signal, continuously adjusts output drive current to move the actuator until actual valve position matches the set value.
Installation Requirements Use proper thick cables for actuator power wiring, separate weak LVDT feedback wires from power lines.
Usage Notes Calibrate zero and full stroke after module replacement, match drive parameters with actuator specifications.
