Technical Specifications 24VDC power supply; multi-channel isolated analog input; on-board signal filtering and overrange protection circuit; operating temperature -40℃ ~ +70℃.
Functional Features High-precision analog signal sampling; signal galvanic isolation and noise filtering; overrange input protection; per-channel fault diagnosis.
Application Scenarios Gas turbine, steam turbine and genset process parameter monitoring cabinets.
Performance Parameters Low measurement error, low signal distortion, stable continuous sampling performance under industrial interference environment.
Structural Characteristics Rack pluggable printed circuit board, onboard signal terminals, built-in EMC filtering components.
Working Principle The board receives weak analog signals from field transmitters. It filters noise, isolates signal and converts analog value into digital data, then transmits processed digital data to the main controller for logic calculation.
Installation Requirements Install near field sensor side as much as possible; separate analog signal cables and high-power power cables; properly ground cable shielding layer.
Usage Notes Carry out channel calibration periodically; avoid overrange signal input which may damage sampling channels.
