Triconex 2201 Digital Input/Output Safety Module

Technical Specifications

  • Power and Physical Parameters
    • It uses a 24V DC power supply, which matches the power configuration of standard industrial control systems.
    • The operating temperature range is -40°C to +70°C, and it can maintain stable operation in extremely cold or high-temperature industrial environments.
    • Its dimensions are 15.5 centimeters × 10.5 centimeters × 2.5 centimeters, and the compact size allows for flexible installation in various control cabinets.
    • It adopts DIN rail mounting, which conforms to common industrial installation standards and simplifies the on-site installation process.
  • I/O and Communication Parameters
    • It is equipped with 16 digital input channels and 16 digital output channels, and can support up to 2048 I/O points when integrated into the system to meet the expansion needs of large-scale safety systems.
    • The maximum output current reaches 2A, which can directly drive most industrial on-site digital output devices without additional power amplification components.
    • It supports multiple communication protocols including Modbus, Ethernet/IP and OPC, and is also equipped with an RS485 communication interface to ensure smooth connection with existing industrial networks.

Description
    • Certification and Compatibility Parameters
      • It obtains SIL 3 certification through TÜV Rheinland authentication, which fully meets the requirements of the international standard IEC 61508:2010 for safety integrity level 3 applications.
      • It is compatible with a wide range of Triconex I/O modules and can work with the TriStation software suite to complete configuration, programming and maintenance operations throughout the safety life cycle.
  • Functional Features
    • Triple Modular Redundancy for Maximum Safety
      • It adopts triple modular redundancy architecture. When one processor or circuit path fails, the other two normal paths can immediately take over the work. The module can tolerate up to two faults without disrupting the industrial process.
      • The redundancy design extends the fault handling window to 72 hours, providing sufficient time for on-site personnel to replace faulty components without affecting the continuous operation of the production process.
    • Powerful Diagnostics and Maintenance Capabilities
      • It is equipped with LED status indicators that clearly display the module’s operating status, communication status and fault information, enabling on-site personnel to quickly identify and locate problems.
      • It has built-in self-testing functions and can perform real-time monitoring on its own hardware and communication links. The diagnostic data can be synchronized to the upper monitoring system for technicians to conduct in-depth fault analysis.
      • It supports online module replacement and online parameter modification. The hot standby slot design ensures that the system does not need to be shut down during maintenance, which avoids production downtime caused by equipment maintenance.
    • Strong Compatibility and Scalability
      • Its modular design supports the connection of various Triconex I/O modules. Users can add or replace related modules according to actual application needs without modifying the overall system structure.
      • It can seamlessly integrate with EcoStruxure Foxboro DCS and other major distributed control systems. The support for multiple communication protocols allows it to be quickly incorporated into existing industrial networks without large-scale transformation of the original system.
  • Application Scenarios
    • Oil and Gas Industry
      • In offshore oil platforms, the module connects various gas detectors, pressure sensors and emergency shutdown valves to the safety instrument system. It monitors gas concentration and pipeline pressure in real time. Once abnormal data is detected, it immediately sends control signals to trigger emergency shutdown operations to prevent explosion and leakage accidents.
      • In natural gas processing plants, it is used in the fire and gas detection system. It collects data from on-site fire detectors and transmits instructions to the sprinkler system and gas cutoff device to quickly respond to fire hazards and reduce property losses.
    • Chemical and Petrochemical Industry
      • In chemical production workshops that produce flammable and explosive materials, the module is integrated into the process safety management system. It controls the operation of reactors, material delivery pumps and discharge valves. It strictly follows preset safety procedures to avoid dangerous reactions caused by abnormal material feeding or temperature fluctuations.
      • In oil refineries, it is applied to the high-integrity pressure protection system. It monitors the pressure of distillation towers and other key equipment in real time and activates pressure relief devices when the pressure exceeds the safety threshold to prevent equipment damage and material leakage.
    • Power Generation Industry
      • In nuclear power plants, it is used in reactor protection systems. It connects temperature, pressure and radiation sensors around the reactor. It transmits safety-related data to the central control room and executes emergency shutdown commands when abnormal parameters occur to ensure the safe operation of the reactor.
      • In thermal power plants, it is integrated into the boiler protection system. It monitors the combustion status and water level of the boiler. It can quickly cut off the fuel supply when dangerous conditions such as insufficient water level occur to avoid boiler explosion accidents.
    • Pharmaceutical and Mining Industries
      • In pharmaceutical production lines involving flammable solvents, the module controls the operation of solvent storage tanks and delivery pipelines. It ensures that the material delivery speed and storage capacity are within the safe range and prevents safety accidents caused by solvent leakage and accumulation.
      • In large coal mines, it is used in underground gas monitoring and ventilation control systems. It connects gas sensors and ventilation fans. It increases the ventilation volume in time when the gas concentration exceeds the standard to ensure the safety of underground operating personnel.
