Description
    • Environmental Parameters
      • The operating temperature range is -40°C to 70°C, and the storage temperature range can reach -40°C to 85°C, adapting to large temperature differences in industrial sites.
      • It has good environmental adaptability and can work normally in common dusty and humid industrial workshop environments without being affected by non-corrosive gases.
  • Functional Features
    • Redundancy Design Ensures Uninterrupted Operation
      • The triple modular redundancy architecture enables the three sub-circuits of the module to perform the same control task independently. When a single sub-circuit fails, the system can realize fault tolerance through voting mechanism without affecting the normal output of signals. This design completely avoids production interruptions caused by single-point faults and ensures the continuity of critical industrial processes.
      • Real-Time Diagnostics Improve Fault Handling Efficiency
      • The built-in real-time diagnostic function can continuously detect faults such as open circuits, short circuits and abnormal loads in field lines. Once a fault is found, it will immediately trigger the corresponding indicator to alarm, and send fault information to the upper controller. This allows maintenance personnel to quickly locate and deal with problems without disassembling the module, greatly reducing maintenance time.
    • Strong Compatibility and Easy Integration
      • It supports multiple communication protocols such as Modbus, RS-232 and RS-485, and can seamlessly integrate with Triconex series products and other industrial automation equipment. The modular design allows it to be quickly installed into the designated rack slot, and plug-and-play can be realized without complex configuration, which shortens the system construction and upgrade cycle.
    • Stable Signal Output and Strong Anti-Interference Ability
      • The 1500 VDC inter-channel isolation design and optical isolation technology effectively isolate external electrical interference and prevent signal distortion caused by interference. At the same time, the module can maintain stable output current and voltage within the rated parameter range, ensuring the reliable operation of on-site executive components.
  • Application Scenarios
    • Oil and Gas Industry
      • In offshore drilling platforms and onshore refineries, it is integrated into emergency shutdown systems and high-integrity pressure protection systems. It controls the opening and closing of emergency shut-off valves and the start-stop of oil transfer pumps. When abnormal pressure or gas leakage is detected, it can quickly send out control signals to cut off the dangerous source and avoid explosion and fire accidents.
      • In long-distance oil and gas transmission pipelines, it is used to control the switching of section valves. It adjusts the valve state according to the real-time monitoring signals of pressure and flow to ensure the safety and stability of oil and gas transmission.
    • Chemical and Nuclear Power Industry
      • In chemical plants, it is applied to reactor safety interlock systems and material feeding control systems. It drives the feeding valves and agitator motors of reactors. When the reaction temperature or pressure exceeds the set threshold, it immediately cuts off the material supply and stops the operation of agitators to prevent uncontrollable chemical reactions.
      • In nuclear power facilities, it is part of the safety-related control system and is responsible for controlling the start and stop of auxiliary safety equipment and the transmission of alarm signals. It ensures that the nuclear power unit can quickly switch to a safe state when abnormal parameters occur, avoiding nuclear safety hazards.
    • Pharmaceutical and Power Industry
      • In pharmaceutical production workshops with strict process requirements, it is used in the safety control system of key production links. It controls the switching of material transmission pipelines and the operation of reaction equipment. When the process parameters such as temperature and pH value deviate, it can immediately cut off the transmission of raw materials to ensure the qualification and safety of pharmaceutical products.
      • In thermal power plants, it is integrated into boiler protection and steam turbine control systems. It controls the opening and closing of safety valves and fuel control valves. When the boiler pressure is too high or the steam turbine has abnormal operation parameters, it can quickly trigger pressure relief or fuel cut-off actions to protect core power generation equipment from damage.
