Ics Triplex T8480C Trusted TMR Analog Output Module

Description

• • Environmental Parameters
    • Temperature Adaptability: The extended operating temperature range is -20°C to 70°C, and the storage temperature range is -40°C to 85°C, enabling it to adapt to extreme temperature fluctuations in industrial sites.
    • Humidity Tolerance: It can operate normally in an environment with a relative humidity of 5% to 95% without condensation, which is suitable for humid industrial environments such as chemical plants and coastal oil platforms.
• Function Features
  • Triple Modular Redundancy Architecture: The module adopts a TMR design. Three independent circuits run in parallel and verify each other’s results. This design ensures that the module can still maintain normal output functions when a single channel or component fails, and fundamentally improves the fault tolerance and reliability of the module.
  • Comprehensive Status Monitoring and Diagnostics: Each channel is equipped with LED indicators to clearly display the on/off status of each channel. It also has a complete self-diagnostic function that can promptly detect potential faults such as channel abnormalities and signal interference, providing intuitive and timely fault prompts for maintenance personnel.
  • Diversified Communication Compatibility: It supports multiple communication protocols including Ethernet and Modbus TCP/IP, and is also compatible with the Triplex bus. This allows it to seamlessly integrate with different types of industrial control systems, realizing efficient data exchange and command transmission between the module and the controller.
  • Hot Standby Redundancy Support: The module supports hot standby operation mode. When the main module has an unexpected fault, it can quickly switch to the standby module without manual intervention. This function avoids system downtime caused by module failures and ensures the continuity of the entire control system.
  • Independent Channel Isolation: Each input and output channel is independently isolated electrically. This isolation design effectively prevents electrical interference between channels and external electrical interference, ensuring the integrity and stability of signal transmission and avoiding misoperation of the module due to interference.
• Application Scenarios
  • Oil and Gas Industry: It is widely used in emergency shutdown systems and fire and gas protection systems of oil drilling platforms and refining facilities. It converts control signals into analog signals to control the opening and closing of pipeline valves and the operating parameters of oil pumps. When abnormal conditions such as gas leakage or excessive pressure occur, it can output accurate analog signals in a timely manner to trigger emergency protection measures.
  • Chemical Industry: It is integrated into the safety instrumented systems of chemical reaction kettles and hazardous chemical storage equipment. It controls the flow rate of chemical raw materials and the temperature regulation components of reaction kettles through stable analog output. Its high accuracy and fault tolerance prevent dangerous accidents such as explosions and leakage caused by unstable process parameters in chemical production.
  • Power Generation Industry: It is applied in the control systems of thermal power and nuclear power plants, especially in the protection links of steam turbines and boilers. It adjusts the operating status of auxiliary equipment such as feed water pumps and air supply fans by outputting precise 4 – 20mA signals. When equipment parameters exceed the safe range, it can quickly adjust the output signal to protect key power generation equipment from damage.
  • Transportation Industry: It is used in the control systems of rail transit signal systems and large ships’ power systems. In rail transit, it assists in adjusting the speed control signals of trains; on ships, it adapts to the humid and vibrating marine environment to control the operation of ship power equipment, ensuring the safe and stable operation of transportation equipment.
