Technical Specifications 24VDC power supply; isolated analog input and output channels; on-board filtering and overvoltage protection circuit. Operating temperature: -40℃ ~ +70℃.
Functional Features High-precision analog sampling and analog signal output; galvanic isolation and noise filtering; overrange protection; channel fault diagnosis.
Application Scenarios Gas turbine, steam turbine and large genset control cabinets.
Performance Parameters Low measurement deviation, stable input and output signal, strong anti-electromagnetic interference capability.
Structural Characteristics Rack pluggable PCB, onboard signal terminals and integrated EMC components.
Working Principle The board collects analog signals from field transmitters, converts analog signals into digital data for main controller, and converts digital commands from main processor into analog signals and outputs to field devices.
Installation Requirements Install near field sensors and actuators; separate analog signal cable and power cable, properly ground shielding layer.
Usage Notes Calibrate each input and output channel regularly; prohibit overrange signal input.
