Technical Specifications 24VDC power supply, multi-channel isolated analog input. Operating temperature: -40℃ ~ +70℃, supports 4-20mA and 0-10V signal acquisition.
Functional Features Analog signal sampling, electrical isolation, over-range detection, channel fault diagnosis, digital filtering.
Application Scenarios Gas engine control cabinets, generator auxiliary parameter monitoring, turbine auxiliary system signal collection.
Performance Parameters High sampling resolution, low temperature drift, channel-to-channel isolation to avoid cross interference.
Structural Characteristics Rack pluggable module, independent LED status indicator for each analog channel.
Working Principle Field analog signals enter the module through the terminal board. After isolation and AD conversion, the digital parameter data is sent to the main control module via internal rack bus for logic processing and threshold comparison.
Installation Requirements Install on the matched 9902 rack, lock connectors tightly, separate analog wiring from power cables.
Usage Notes Confirm signal type and range for each channel before power on, avoid overvoltage input to analog channels.
