Description

• • Communication and Environmental Parameters
    • Supported Protocols: Modbus, Ethernet/IP, DeviceNet, ControlNet
    • Operating Temperature: -40°C to 70°C
    • Power Supply Requirement: 24VDC to 48VDC
• Functional Features
  • Triple Modular Redundancy Architecture: The module uses a triple modular redundancy design. When a single component or channel fails, the system can automatically isolate the faulty part and rely on the other two normal channels to maintain accurate signal collection and transmission. This design completely avoids single-point failures and ensures the continuous and stable operation of the safety instrumented system.
  • High-Density Input Design: It integrates 64 analog input points in a single module. This high-density integration reduces the number of modules required in the control cabinet, saves installation space, simplifies the wiring structure of the system, and at the same time lowers the overall investment and maintenance costs of the industrial control system.
  • Strong Anti-Interference Capability: It adopts differential input and DC coupling design. The differential input method effectively suppresses common-mode interference in the industrial environment, while DC coupling not only simplifies the installation process but also further enhances the stability of signal transmission, ensuring that the module can obtain accurate signals even in complex and harsh electromagnetic environments.
  • Hot-Swappable and Easy Maintenance: The module supports hot-swappable functionality. When a fault occurs, maintenance personnel can replace the faulty module online without shutting down the entire safety system. This minimizes production downtime caused by equipment maintenance and greatly improves the maintainability and operational efficiency of the industrial system.
  • Multi-Protocol Compatibility: It is compatible with multiple mainstream industrial communication protocols. This allows the module to seamlessly integrate with different types of industrial control systems and equipment, breaking the communication barriers between different devices. It adapts to the diverse configuration needs of industrial automation systems and enhances the flexibility of system construction.
• Application Scenarios
  • Oil and Gas Industry: It is deployed in offshore drilling platforms and onshore oil transmission pipeline systems. It collects analog signals such as pressure and temperature from pipeline sensors and gas concentration signals from leakage detection devices. The data collected is transmitted to the emergency shutdown system. When abnormal parameters are detected, the system can quickly trigger protective measures to avoid major safety accidents such as oil and gas leakage and explosions.
  • Petrochemical Industry: It is applied to chemical reactors, distillation towers and other key production equipment. It collects real-time analog data such as reaction temperature, pressure and raw material flow during the chemical production process. It provides data support for the safety interlock system of the production process. It ensures that the production process is carried out within the set safe parameter range and prevents dangerous reactions caused by parameter deviations.
  • Power Generation Industry: It is used in thermal power plants, nuclear power plants and other power generation facilities. It monitors analog parameters such as steam pressure and temperature of boilers, generator bearing temperature and transformer oil temperature. It helps the power control system adjust operating parameters in a timely manner. It ensures the stable operation of power generation equipment and avoids power outages or equipment damage caused by abnormal parameters.
  • Pharmaceutical Industry: It is integrated into pharmaceutical production lines, especially in the processes of drug mixing and high-temperature sterilization. It collects analog signals such as temperature and pressure in the production equipment. It ensures that the production process meets strict pharmaceutical production standards. It guarantees the stability of drug quality and the safety of the production process, and complies with the strict regulatory requirements of the pharmaceutical industry.
  • Metallurgical Industry: It is installed in blast furnaces, steelmaking converters and other high-temperature smelting equipment. It collects analog signals such as furnace temperature, molten iron level and flue gas concentration. It transmits the data to the smelting control system. It helps operators adjust smelting parameters in real time, improves smelting efficiency, and prevents equipment damage and production accidents caused by extreme working conditions.
  • Environmental Monitoring Field: It is used in industrial waste gas and wastewater treatment monitoring systems. It collects analog signals such as pollutant concentration, pH value and turbidity in waste water and gas. It provides accurate data for environmental protection monitoring and control systems. It ensures that enterprises discharge pollutants in accordance with national standards and helps achieve environmentally friendly production.
