Triconex SDO3411 Relay Output Digital Module

Description

• Environmental Specifications
  • The operating temperature range is -20°C to 70°C, which can adapt to the temperature changes of most indoor industrial workshops and outdoor equipment stations.
  • The structure is sturdy and durable, and it can resist the vibration generated by the operation of industrial equipment on site, maintaining stable performance without being affected by general industrial vibration.

Functional Characteristics

• Triple Modular Redundancy and High Fault Tolerance
  • It is built with a triple modular redundancy architecture. It is equipped with three identical and independent control channels inside. Even if one or two internal components fail, the module can still operate continuously without interrupting the normal progress of the industrial process.
  • The advanced fault diagnosis function can actively detect faults such as open circuits and short circuits of external connected loads. Once a fault is found, it will promptly feed back the fault information to the upper controller to avoid accidents caused by equipment failure.
• Flexible Configuration and Easy Integration
  • It supports two configurations of 16 or 32 output channels, and is compatible with two power supply and output voltage standards. It can be flexibly adjusted according to the number of on-site controlled equipment and power supply conditions.
  • It is highly compatible with the Triconex safety instrumented system. It can be seamlessly integrated with other modules of the same series, which is convenient for users to expand the number of system output points and upgrade the system functions.
• Convenient Maintenance and High Operational Continuity
  • It has a hot-swappable design. Maintenance personnel can replace the faulty module when the entire safety system is running normally without shutting down the production line.
  • The modular design and clear panel marking make daily inspection and troubleshooting more convenient. Maintenance personnel can quickly locate the module and related fault points, which shortens the maintenance time and reduces production losses.

Application Scenarios

• Oil and Gas Industry
  • It is applied to emergency shutdown systems of offshore drilling platforms. When the gas concentration sensor and pressure sensor detect abnormal data, the module can output signals in time to control the closure of valves and the shutdown of drilling equipment, avoiding oil and gas leakage and explosion accidents.
  • It is used in the fire and gas systems of onshore oil depots. When a fire or gas leakage is detected, it can trigger the start of fire suppression equipment and the sounding of alarms through output signals, and at the same time control the shutdown of oil transfer pumps to prevent the spread of risks.
• Chemical and Mining Industry
  • It is integrated into the safety control system of chemical reactors. It controls the opening and closing of feeding valves and the operation of temperature control equipment according to the instructions of the upper system, ensuring that the chemical reaction is carried out within the set safe parameters.
  • It is deployed in mining production systems. It is used to control the operation of mining conveyors, ventilation fans and other equipment. When dangerous situations such as tunnel collapse precursors are detected, it can immediately output stop signals to protect the safety of mining personnel.
• Power Generation Industry
  • It is used in the safety system of thermal power plants. It controls the switch state of auxiliary equipment such as boiler feed pumps and induced draft fans. When the parameters such as boiler pressure and temperature are abnormal, it can quickly cut off the operation of related equipment to avoid boiler explosion.
  • It is applied to the auxiliary control system of hydropower stations. It controls the opening and closing of water inlet valves and the operation of power generation unit auxiliary equipment, ensuring the stable operation of hydropower generation and responding to emergency shutdown instructions in time.
• General Industrial Automation
  • It is used in the production lines of large-scale pharmaceutical factories. It controls the operation of material conveying equipment and mixing equipment, ensuring that each production link is carried out in an orderly manner and meeting the safety and hygiene standards of pharmaceutical production.
  • It is integrated into the automatic control system of food processing plants. It controls the start and stop of sterilization equipment, packaging machinery and other equipment, and ensures the safety and stability of the food processing process by accurately executing control signals.
