TRICONEX 4351B

Technical Specifications:

• It is designed for high availability and fault tolerance, ensuring continuous operation even in the event of hardware failures.
• The system supports safety integrity levels up to SIL 3 according to IEC 61508, making it suitable for critical safety applications.
• It operates with a triple modular redundant (TMR) architecture where three independent systems process data simultaneously and compare results to ensure accuracy and reliability.

• System Architecture: The 3201 model is part of a triply redundant architecture, offering fault tolerance and high availability. This triple modular redundancy (TMR) ensures continuous operation even in the event of hardware failures.
• Processor Capabilities: Equipped with powerful processors capable of executing complex control logic and diagnostics simultaneously across three channels to ensure reliable operation.
• Memory: Includes sufficient memory for storing application programs, historical data, and system parameters, supporting extensive configuration and logging capabilities.
• Communication Interfaces: Supports various communication protocols including Modbus, OPC, and proprietary interfaces, enabling seamless integration with distributed control systems (DCS) and other plant networks.

• • Electrical Parameters
    • The nominal output voltage is 120 VDC, with a voltage range of 90 - 150 VDC and a maximum withstand voltage of 160 VDC. The typical voltage drop of the module is less than 1.5 V, and the power module load is less than 10 watts.
    • Each output point has a maximum current of 0.8 A, a surge current of 4 A within 10 milliseconds, a minimum required load current of 30 mA, and a maximum load leakage current of 4 mA.
    • The field terminal is equipped with a 1 A fast - acting fuse, and the point isolation voltage can reach 1500 VDC / 2500 VDC, which can effectively isolate electrical interference.
  • Physical and Indicator Parameters
    • The module weighs 5000 grams, and its shell adopts a steel - blue robust structure, which can adapt to the installation and use of various industrial control cabinets.
    • It is equipped with multiple diagnostic indicators, including pass, fault, active and power indicators for overall module status, as well as an independent load indicator for each output point, which can directly reflect the working state of the module and each output point.
