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