Triconex 3806E Triple Modular Redundancy Analog Output Module

Description

• • Physical Parameters
    • Dimensions: The module measures 170mm x 105mm x 50mm, and its compact size facilitates installation in standard industrial control cabinets.
    • Housing and Identification: It adopts a light green housing that allows maintenance personnel to quickly locate and identify the module among numerous equipment components.
    • Protection Level: It has an IP65 protection level, which can effectively prevent the intrusion of dust and low-pressure water jets, adapting to relatively harsh on-site installation environments.
  • Environmental Parameters
    • Operating Temperature: It maintains stable performance within the range of -40°C to +70°C, which can meet the operating requirements of low-temperature outdoor areas and high-temperature industrial workshops.
    • Anti-interference Performance: The built-in isolation protection design enables it to resist electromagnetic interference commonly existing in industrial environments, ensuring the stability of signal output in complex electrical environments.
• Functional Features
  • Triple Modular Redundancy for Fault Tolerance: The triple modular redundancy design enables the module to receive signals from three independent channels of the processor simultaneously. It conducts voting on the three sets of data, selects valid signals to drive outputs, and shuts down faulty channels immediately when abnormalities are detected. This design completely eliminates the impact of single-point faults and ensures continuous operation of the safety system.
  • Dual-Range Analog Output for Diversified Needs: The module covers both standard 4 – 20mA and high 20 – 320mA current output ranges. The standard range is suitable for conventional actuators such as small valves and sensors, while the high-current range can drive large-power equipment. This dual-range design meets the control needs of different types of on-site equipment without the need for additional adapter modules.
  • Comprehensive Self-Diagnosis and Calibration: It monitors its own current output in real-time by taking input voltages as references and maintains an internal voltage reference to achieve self-calibration. Each channel is equipped with two independent current loopback circuits for verifying signal accuracy and actual current flow. It can trigger load alarm indicators when encountering problems such as open circuits, facilitating timely troubleshooting.
  • Easy Integration and Maintenance: It is equipped with multiple communication interfaces including Ethernet, RS-232, and RS-485, which can be seamlessly integrated with Triconex series controllers and upper-level monitoring systems. Its modular design and standardized interfaces simplify the installation process. The light green color-coded housing and clear status indicators allow maintenance personnel to quickly identify and replace modules.
  • Reliable Over-Voltage and Reverse Voltage Protection: The module provides continuous over-voltage protection below 42.5VDC and reverse voltage protection for the external loop power supply. These protection functions can effectively prevent module damage caused by sudden voltage surges or incorrect wiring during industrial operations, significantly extending the service life of the module.
• Application Scenarios
  • Oil and Gas Industry: It is deployed in offshore drilling platforms and onshore natural gas pipelines. It converts control signals into analog signals to regulate the opening and closing of pipeline valves and the operation of transfer pumps. When abnormal pressure or leakage is detected, it can quickly adjust the actuator to cut off the transmission path and avoid major safety accidents such as explosions.
  • Chemical Industry: It is installed in chemical reactors and distillation systems. It controls the flow of raw material delivery pumps and the opening of exhaust valves through precise current signals. It ensures that parameters such as reaction temperature and pressure remain within the safe range, preventing dangerous reactions caused by process fluctuations.
  • Power Industry: It is applied to thermal power plants and nuclear power auxiliary systems. In thermal power plants, it regulates the fuel supply volume and the flow of cooling water by controlling relevant actuators. In nuclear power plants, it is used to monitor and control the operation of nuclear reactor auxiliary equipment, ensuring the safe and stable operation of power generation equipment and avoiding equipment damage due to parameter deviations.
  • Metallurgical Industry: It is used in steelmaking blast furnaces and aluminum smelting equipment. The high-current output range of the module can drive large-scale hydraulic valves and heating system actuators, precisely controlling smelting temperature and molten metal flow rate, which helps improve the quality of metal products and protect the furnace body from excessive temperature damage.
  • Pharmaceutical Industry: It is used in drug mixing, sterilization, and filling production lines. It controls the operation of dosing pumps and temperature control valves through standard current signals, ensuring that parameters such as mixing ratio and sterilization temperature meet GMP standards. This maintains the consistency of drug quality and avoids batch product defects caused by process instability.
