Technical Specifications 24VDC power supply, proportional current drive output, integrated LVDT excitation and feedback input. Operating temperature: -40℃ ~ +70℃.
Functional Features Command conversion, proportional current output, LVDT signal acquisition, drive loop short-circuit protection.
Application Scenarios Fuel actuator and governing valve closed-loop drive for gas and diesel engine control systems.
Performance Parameters High drive linearity, accurate position tracking, fast command response.
Structural Characteristics Rack pluggable module, drive and feedback channel LED indicators.
Working Principle The module compares the target position command with the LVDT position feedback signal, adjusts output current continuously to make the valve position follow the set value.
Installation Requirements Use dedicated shielded cable for LVDT feedback, separate feedback cables from high-current drive cables.
Usage Notes Complete zero and full stroke calibration before commissioning, check LVDT wiring integrity regularly.
