Triconex 2291 Functional Module for Safety Instrumented Systems

Description

• Auxiliary Logic Operation Enhancement
  • The module undertakes part of the logic operation tasks of the main controller, reducing the operational burden of the main controller and improving the overall response speed of the system.
  • It can independently process simple logic commands such as signal filtering and threshold judgment, and feed back the processed results to the main controller, shortening the system’s decision-making cycle.
• Stable Signal Conversion and Transmission
  • It realizes the mutual conversion between different types of signals, which can convert the digital signals from the main controller into analog signals that can be recognized by peripheral equipment, and vice versa.
  • The signal transmission delay is less than 1 microsecond, ensuring that the control signals and feedback signals are transmitted without delay, avoiding misoperation of on-site equipment caused by signal lag.
• Strong System Compatibility
  • It is fully compatible with various models of Triconex safety controllers. There is no need to modify the core program of the system during installation and use, and it can be put into use after simple parameter configuration.
  • It supports mainstream industrial communication protocols such as Modbus and Ethernet, and can also achieve data interaction with other automation systems such as DCS and PLC, enhancing the integration of the entire industrial control system.
• Real-time Fault Self-diagnosis
  • It is equipped with an independent fault diagnosis circuit, which can continuously monitor its own working status, including circuit connection, power supply stability and signal transmission status.
  • When an abnormality is detected, it will immediately send a fault signal to the main controller and display the fault location through the indicator light on the module, facilitating maintenance personnel to quickly locate and solve the problem.

• Oil and Gas Industry
  • In offshore drilling platforms, it is used in the safety interlocking system, assisting the main controller in processing the signals of wellhead pressure and flow sensors, and converting the control signals to drive the action of pipeline safety valves, ensuring the safety of drilling operations.
  • In long-distance oil and gas transmission pipeline stations, it cooperates with the main control system to process the signals of leakage detection equipment and convert them into execution signals for emergency cut-off valves, which can quickly respond to pipeline leakage accidents.
• Chemical and Petrochemical Industry
  • In large chemical plants, it is deployed in the reaction kettle control system, responsible for converting the temperature and pressure signals collected by the sensors into signals recognizable by the main controller, and transmitting the controller’s adjustment commands to the heating and pressure relief equipment.
  • In hazardous chemical storage areas, it assists the fire protection system to process the signals of gas detectors, and triggers the start of spray equipment and exhaust devices through signal conversion, reducing the risk of fire and explosion.
• Power Generation Industry
  • In thermal power plants, it is used in the boiler combustion control system, processing the signals of coal feeding speed and flue gas composition sensors, and converting control signals to adjust the opening of the air supply valve, ensuring efficient and stable combustion of the boiler.
  • In nuclear power plant auxiliary systems, it is applied to the cooling system and radiation monitoring system, undertaking signal conversion and auxiliary operation tasks, and meeting the strict safety and stability requirements of nuclear power operations.
• Metallurgical and Automobile Manufacturing Industry
  • In the metallurgical industry, it is deployed in blast furnace control systems, processing the signals of furnace temperature and molten iron level sensors, and converting them into control signals for feeding and cooling equipment, ensuring the smooth progress of the smelting process.
  • In automated automobile production lines, it is used in the welding and painting workshops’ safety control systems, assisting in processing equipment operation status signals and realizing the rapid switching of equipment working states and emergency stop functions.
