Triconex 3807 Triple Modular Redundancy Bipolar Analog Output Module

Description

• • Physical Parameters
    • Weight: The module weighs 5000 grams, and its weight ensures structural stability during installation and operation.
    • Housing Feature: It uses a light green color – coded housing, which helps maintenance personnel quickly distinguish and locate the module among a large number of control components.
  • Environmental Parameters
    • Operating Temperature Adaptability: It can maintain stable performance within the common industrial temperature range of 0°C to 60°C, which is compatible with the temperature environment of most indoor industrial workshops and control rooms.
    • Voltage Adaptability: Its external loop power supply can adapt to a ±15% to +20% voltage fluctuation range, and it can work normally even when the power supply voltage changes slightly, enhancing its adaptability to the unstable power supply environment in some industrial sites.
• Functional Features
  • Triple Modular Redundancy Ensures Fault Tolerance: Adopting triple modular redundancy technology, the module processes and verifies signals through three independent circuit paths. When one path has a fault, the other two paths can continue to maintain normal signal output, which completely avoids system downtime caused by single – point faults and greatly improves the reliability of the safety instrumented system.
  • Bipolar Output Meets Special Control Needs: Unlike modules with only positive current output, its -60 to 60mA bipolar current output can meet the control requirements of special industrial equipment that requires bidirectional adjustment. For example, it can control the forward and reverse movement of some precision actuators or the increase and decrease of parameters in both positive and negative directions.
  • Stable Performance with Strong Protection: The continuous +36VDC over – range protection and reverse voltage protection for the power supply can effectively resist damage to the module due to voltage surges or incorrect wiring during industrial operations. The 150 – ohm maximum load capacity ensures that the module can stably drive various matching on – site actuators.
  • Intuitive Diagnostic Indicators Facilitate Maintenance: The multiple integrated status indicators can directly display the module’s operating conditions such as normal operation, fault occurrence, and power supply status. Maintenance personnel can quickly judge the module’s status without complex testing equipment, thus shortening the troubleshooting time and improving maintenance efficiency.
  • Easy Integration with Existing Systems: It adopts a standardized design that is consistent with other Triconex series modules. It can be seamlessly integrated into the Triconex safety instrumented system without the need for complex adapter components. This not only simplifies the system construction process but also ensures the stability of data transmission between the module and the controller.
• Application Scenarios
  • Oil and Gas Industry: It is applied in emergency shutdown systems and high – integrity pressure protection systems of offshore drilling platforms and onshore oil transmission pipelines. It controls the opening and closing of bidirectional regulating valves through bipolar current signals. When abnormal pressure or leakage is detected, it can quickly adjust the valve position to cut off the oil and gas transmission path and avoid accidents such as explosions and large – scale leaks.
  • Chemical Industry: It is used in chemical reactor temperature and pressure control systems and material mixing systems. For reactors that need to adjust the cooling and heating systems alternately, the bipolar output can flexibly control the flow of cooling medium and heating medium. In material mixing systems, it can precisely adjust the feed rate of different materials to ensure the stability of the chemical reaction process.
  • Power Industry: It is deployed in the auxiliary control systems of thermal power plants and nuclear power plants. In thermal power plant boiler systems, it controls the opening of air intake and exhaust regulating valves to adjust the combustion efficiency. In nuclear power plant auxiliary systems, it is used to control the operation of coolant circulation pumps and regulating valves, ensuring that the temperature and pressure of the nuclear reactor system are within the safe range.
  • Turbomachinery Control: It is integrated into turbomachinery control systems in various industries. It can control the speed and load of turbines through bipolar analog signals. For example, in gas turbine units, it adjusts the fuel supply and air intake volume to maintain the stable operation of the turbine and respond quickly to load changes.
  • Pharmaceutical Industry: It is used in precision mixing and temperature control systems of pharmaceutical production lines. Some pharmaceutical processes require bidirectional adjustment of parameters such as mixing speed and temperature. The bipolar output of the module can accurately control the corresponding actuators to ensure that the drug production process meets GMP standards and guarantee the uniformity and quality of drug products.
