Technical Specifications 24VDC power supply; multi-channel isolated analog input; on-board signal filtering and overrange protection. Operating temperature: -40℃ ~ +70℃.
Functional Features High-precision analog sampling; signal galvanic isolation and noise filtering; overrange protection; per-channel fault diagnosis.
Application Scenarios Turbine and genset process parameter monitoring cabinets.
Performance Parameters Low measurement deviation, stable sampling performance under complex industrial interference environment.
Structural Characteristics Rack pluggable PCB, onboard signal terminals and EMC filter components.
Working Principle The board receives weak analog signals from field transmitters, filters noise, isolates signals and converts analog quantity into digital data, and transmits processed data to main controller for algorithm calculation.
Installation Requirements Install near field sensors; separate analog signal cable and power cable, ground shielding properly.
Usage Notes Periodically calibrate each sampling channel; avoid overrange input.
