• Functional Features
  • Triple Modular Redundancy Architecture: The triple modular redundancy design enables three independent circuits to perform the same signal collection and processing tasks simultaneously. It uses a voting mechanism to determine the final output data. Even if one circuit fails, the system can still maintain normal operation, completely avoiding the impact of single-point failures on the overall system.
  • High-Density and High-Precision Acquisition: With 64 single-ended input channels, the module can collect analog signals from a large number of field sensors at the same time, which is suitable for large-scale industrial production lines that require multi-point monitoring. The programmable 12-bit or 14-bit resolution ensures that the module can meet the precision requirements of different industrial processes.
  • Strong Anti-Interference Capability: It has excellent common-mode and normal-mode rejection ratios. The high input resistance and reasonable isolation design can effectively suppress electromagnetic interference, voltage fluctuations, and other interference factors in complex industrial environments, ensuring the accuracy and stability of the collected signals.
  • Flexible Configuration and Easy Maintenance: Users can flexibly set parameters such as input range, resolution, and update rate according to specific application needs. The modular design and removable structure allow for quick installation and replacement. The real-time diagnostic indicators can help maintenance personnel quickly locate faults, greatly shortening maintenance time.
  • Wide Compatibility: It can be seamlessly integrated with Triconex series control systems. It supports multiple communication protocols and can easily communicate and share data with PLC, SCADA systems, and other equipment, which reduces the difficulty of system integration.
• Application Scenarios
  • Oil and Gas Industry: Deployed in onshore refineries and offshore drilling platforms, it collects analog signals from pressure and flow sensors in oil and gas pipelines and storage tanks. It monitors the operating status of key equipment in real time. When abnormal parameters are detected, it triggers the emergency shutdown system to prevent accidents such as pipeline leakage and explosion.
  • Nuclear Power Industry: Used in nuclear reactor auxiliary control systems, it monitors parameters such as temperature and pressure of the reactor coolant system and steam generator. The triple modular redundancy design ensures that the data collection function is not interrupted even in extreme conditions, which is crucial for the safe operation of nuclear power plants.
  • Petrochemical Industry: Applied to chemical reactors, distillation towers, and other equipment, it collects analog signals related to chemical reactions. It transmits the data to the control system to adjust reaction conditions in a timely manner, avoiding violent reactions or product quality problems caused by parameter deviations.
  • Power Generation Industry: Installed in thermal power plants and hydropower stations, it monitors the temperature, pressure, and flow parameters of boilers, steam turbines, and transformers. It helps the control system optimize the operation efficiency of power generation equipment and prevents equipment damage due to abnormal parameters, ensuring stable power supply.
  • Pharmaceutical Industry: Integrated into pharmaceutical production lines, it collects analog signals from sensors in processes such as drug mixing and high-temperature sterilization. It ensures that each production link meets GMP standards, avoiding batch quality problems of drugs caused by unstable process parameters.
  • Metallurgical Industry: Used in blast furnaces and steelmaking converters, it collects temperature and pressure signals during the smelting process. It provides data support for adjusting smelting parameters, which ensures the mechanical properties of metal products and prevents furnace lining damage caused by excessive local temperatures.
