Technical Specifications 24VDC power supply, built-in excitation source for LVDT/RVDT, multi-channel position feedback input. Operating temperature: -40℃ ~ +70℃.
Functional Features LVDT excitation driving, position signal conditioning, position value conversion, sensor wire break detection.
Application Scenarios Fuel actuator valve position feedback, steam governing valve position monitoring.
Performance Parameters High position resolution, low measurement drift, stable feedback signal.
Structural Characteristics Rack pluggable module, position channel status LED indicators.
Working Principle The module provides excitation AC signal for the LVDT sensor, processes the differential feedback signal and calculates the actual displacement of the valve spool.
Installation Requirements Use matched shielded LVDT cable, keep feedback cable away from high-current drive cables.
Usage Notes Calibrate zero and full stroke position after wiring, check sensor wiring integrity periodically.
