Triconex DO3625A Digital Output Module

Description

• Triple Modular Redundancy for Fault Tolerance
  • The triple modular redundancy architecture is adopted. Each sub-circuit independently executes the same control task, and the system can automatically shield the faulty sub-circuit when a single hardware fault occurs.
  • This design avoids system downtime caused by local component failures, and ensures the continuous and stable operation of key control functions in safety-critical scenarios.
• Real-time Diagnostics and Fault Isolation
  • It is equipped with advanced real-time diagnostic functions, which can continuously monitor the working status of each output channel and the connection status of on-site lines.
  • It can quickly detect faults such as line disconnection and abnormal current, and isolate the faulty channel in time to prevent the spread of faults to the entire system.
  • The matching LED indicators can clearly display the working and fault status of each channel, which helps maintenance personnel quickly locate the problem.
• Strong Compatibility and Easy Integration
  • It supports multiple communication protocols such as Modbus, RS-232, RS-485 and Ethernet, and can seamlessly connect and exchange data with different types of industrial automation equipment and control platforms.
  • It can be perfectly integrated into Triconex Tricon and Trident series systems, and can be directly added to the existing system architecture during system expansion without modifying the core program.
• Fast Response and Stable Output
  • The response time of the module is less than 1 microsecond, which can quickly convert the logic signal from the controller into an executable output signal, ensuring the timeliness of the action of the on-site actuator.
  • The output signal is stable and has low signal fluctuation, which can meet the precise control requirements of on-site equipment and avoid misoperation of the actuator caused by signal instability.

• Oil and Gas Industry
  • It is widely used in emergency shutdown systems and safety interlocking systems of offshore drilling platforms and onshore oilfields, controlling the opening and closing of safety valves and cut-off valves to quickly respond to risks such as oil and gas leakage and overpressure.
  • In LNG and LPG processing plants, it is used to drive the actuators of storage tank pressure relief valves and pipeline cut-off devices to ensure the safe and stable operation of the processing process.
• Chemical and Petrochemical Industry
  • It is applied to the emergency discharge system of reaction kettles in chemical plants, controlling the opening of discharge valves when the temperature or pressure of the reaction kettle exceeds the safety threshold to avoid dangerous reactions.
  • It is used in the toxic gas leakage protection system, which can trigger the start of the exhaust device and the closing of the isolation valve through the actuator, reducing the harm of toxic gas leakage.
• Power Generation Industry
  • In thermal power plants, it is integrated into boiler and steam turbine protection systems to control the cut-off of fuel supply pipelines and the start of emergency cooling devices, preventing equipment damage caused by overtemperature and overpressure.
  • In nuclear power plants, it is used in auxiliary safety systems to control the operation of cooling system valves and pumps, which meets the strict safety operation standards of nuclear power facilities.
• Other High-risk Fields
  • In the pharmaceutical industry, it is used in the safety interlocking system of sterile pharmaceutical production lines to control the on-off of material conveying pipelines and the emergency stop of reaction equipment, ensuring that the production process complies with safety specifications.
  • In large-scale automated production lines, it is applied to the safety control system to realize the emergency stop function of the production line when a fault occurs, avoiding the expansion of production accidents and reducing economic losses.
