Technical Specifications 24VDC power supply; multiple galvanic isolated analog input channels; filtering and overrange protection circuit. Operating temperature: -40℃ ~ +70℃.
Functional Features High-precision analog sampling; signal isolation and noise filtering; overrange protection; per-channel fault diagnosis.
Application Scenarios Gas turbine, steam turbine and genset process monitoring cabinets.
Performance Parameters Low measurement error, low signal distortion, stable sampling under industrial EMI.
Structural Characteristics Rack pluggable PCB, onboard signal terminals, EMC filtering components.
Working Principle Weak analog signals from field transmitters enter the board, filtered and isolated, then converted to digital data and transmitted to main controller for logic calculation.
Installation Requirements Install close to field sensors; separate analog signal cables and high-power cables.
Usage Notes Periodic channel calibration required; prohibit overrange input.
