Technical Specifications 24VDC power supply, proportional current drive output, LVDT/RVDT feedback input. Operating temperature: -40℃ ~ +70℃.
Functional Features Control command conversion, proportional current output, valve position feedback acquisition, drive loop protection.
Application Scenarios Fuel actuator closed-loop drive for diesel and gas engine governor system.
Performance Parameters High drive linearity, accurate position control, fast response to command change.
Structural Characteristics Standalone drive module, status LED indicators for drive and feedback channel.
Working Principle The module receives governor command signal, compares it with valve position feedback signal, adjusts output current continuously to keep the valve position consistent with target value.
Installation Requirements Arrange thick cables for actuator drive loop, separate feedback shielded cable from power cable.
Usage Notes Complete zero and full stroke calibration before commissioning, check LVDT wiring regularly.
