    • Power Supply: 24 VDC, which matches the power supply standards of most industrial control systems
• Functional Features
  • Triple Modular Redundancy Architecture: The module adopts a triple modular redundancy structure. Three independent input channels run control procedures separately and use a mid – value selection algorithm for data voting. Even if a single channel fails, the system can still maintain normal temperature data collection and transmission, which completely avoids the impact of single – point failures on the overall system.
  • Strong Anti – Interference Capability: It has excellent common mode and normal mode rejection capabilities. The high common mode rejection ratio can effectively suppress electromagnetic interference in industrial environments. The 1500 Vrms isolation voltage prevents signal crosstalk between channels. This ensures that the module can obtain accurate temperature data even in complex electromagnetic environments.
  • Dedicated Thermocouple Signal Processing: It is specially designed for thermocouple signal collection and integrates thermocouple linearization and cold – junction compensation functions. It can accurately convert the weak millivolt – level signals generated by thermocouples into standard digital temperature values, which meets the needs of high – precision temperature monitoring in industrial production.
  • Convenient Maintenance with Hot – Swap Support: The module supports hot – swap operation. Maintenance personnel can replace the faulty module online without shutting down the entire safety system. This greatly shortens the downtime caused by equipment maintenance and improves the operational efficiency of the industrial production line.
  • Comprehensive Built – in Diagnostic Functions: It is equipped with multiple diagnostic indicators to show pass, fault, active and cold – junction fault statuses respectively. The built – in microprocessor can diagnose the hardware faults of the module and the faults of on – site lines. It sends out fault alarm information in a timely manner to help maintenance personnel quickly locate and solve problems.
• Application Scenarios
  • Oil and Gas Industry: It is installed on offshore drilling platforms and onshore oil transmission pipelines. It monitors the temperature of oil and gas storage tanks and transmission pipelines in real time through connected thermocouples. When the temperature exceeds the safe threshold due to pipeline blockage or equipment failure, it sends signals to the emergency shutdown system to prevent pipeline rupture and oil and gas leakage accidents.
  • Petrochemical Industry: It is applied to high – temperature reaction equipment such as chemical reactors and cracking furnaces. It collects real – time temperature data during chemical reactions. It transmits the data to the safety interlock system. The system adjusts reaction conditions according to the data to avoid violent reactions or material deterioration caused by excessive temperature fluctuations.
  • Power Generation Industry: It is deployed in thermal power plants and nuclear power auxiliary systems. It is used to monitor the temperature of key equipment such as boiler furnaces, steam turbines and transformers. It helps the control system adjust fuel supply and cooling systems in a timely manner. It prevents equipment damage due to overheating and ensures the stable and continuous output of electric power.
  • Metallurgical Industry: It is installed in blast furnaces, steelmaking converters and heat treatment equipment. It monitors the temperature of molten steel, furnace linings and metal workpieces during the smelting and heat treatment processes. It provides data support for adjusting smelting parameters and heat treatment procedures. It ensures the mechanical properties and quality of metal products and avoids furnace damage caused by local overheating.
  • Pharmaceutical Industry: It is integrated into pharmaceutical production lines, especially in processes such as high – temperature sterilization and vacuum drying. It monitors the temperature uniformity in the equipment. It ensures that each link of drug production meets GMP standards. It guarantees the effectiveness and safety of drugs and avoids batch drug quality problems caused by temperature non – compliance.
  • Hazardous Chemical Storage Industry: It is used in storage warehouses for flammable and explosive chemical reagents. It monitors the temperature of storage tanks containing volatile and heat – sensitive chemicals. When the ambient temperature rises abnormally, it triggers the cooling system and alarm device in time to prevent chemical combustion or explosion caused by high temperature.
