Technical Specifications 24VDC power supply; multi-channel isolated analog input; built-in signal filtering and overvoltage protection. Operating temperature: -40℃ ~ +70℃.
Functional Features High-precision analog signal acquisition; noise filtering and signal isolation; overrange input protection; per-channel fault detection.
Application Scenarios Gas turbine, steam turbine and genset process parameter monitoring cabinets.
Performance Parameters Low measurement error, stable signal transmission, strong anti-electromagnetic interference capability.
Structural Characteristics Rack pluggable PCB, onboard terminals for analog signal wiring, integrated EMC components.
Working Principle The board receives analog signals from field transmitters, filters interference, isolates signals and converts analog values into digital data for main controller logic calculation.
Installation Requirements Install close to field sensors; separate analog signal cable and power cable; properly ground cable shielding layer.
Usage Notes Calibrate each channel periodically; prohibit overrange signal input to avoid channel damage.
