Triconex 4000196-350 32-Point Triple Modular Redundancy Digital Input Module

Description

• • Physical Parameters
    • Dimensions: The module adopts a standard industrial design, with an overall dimension that matches the Triconex Tricon system chassis. Its net weight is about 2.27 kg, which is convenient for installation and fixation in the control cabinet.
    • Status Indicators: It is equipped with an independent status indicator for each input point, which can clearly display the on or off state of each channel, facilitating on – site personnel to check the working status of the module in real – time.
    • Connector Type: It is configured with a standard industrial terminal connector that is compatible with Triconex’s dedicated connection cables, simplifying on – site wiring and disassembly operations.
  • Environmental Parameters
    • Operating Temperature: It can operate stably in the temperature range of – 40°C to 70°C, adapting to extreme temperature conditions in industrial sites such as outdoor oil fields and high – temperature workshops.
    • Storage Temperature: It can be safely stored in an environment of – 55°C to 85°C, maintaining stable performance during long – term storage and long – distance transportation.
    • Humidity Adaptability: It can work normally in an environment with a relative humidity of 5% – 95% without condensation, which is suitable for humid industrial environments such as coastal chemical plants and water treatment facilities.
    • Vibration Resistance: It can withstand a certain intensity of vibration in industrial environments, which ensures stable operation when installed near equipment such as industrial pumps and compressors that generate continuous vibration.
• Functional Features
  • Triple Modular Redundancy Architecture Ensures Fault Tolerance: The module uses three independent circuit channels to collect and verify signals at the same time. Through the two – out – of – three voting mechanism, it confirms the final signal state. Even if one of the circuit channels fails, the module can still output accurate signals, which completely avoids the impact of single – point faults on the safety of the entire control system.
  • Independent Isolation Design Prevents Signal Interference: Each of the 32 input points adopts an independent isolation design. With a minimum isolation of 1000 VAC and 1500 VDC, it can effectively isolate electrical disturbances between different input channels and external circuits, preventing signal distortion or false triggering caused by interference and ensuring the accuracy of signal collection.
  • Real – time Status Monitoring Facilitates Troubleshooting: Each input point is equipped with a dedicated status indicator, which can directly display the on or off state of the point. Meanwhile, the module has built – in diagnostic functions that can quickly detect abnormal states such as abnormal input voltage and poor wiring, helping maintenance personnel quickly locate fault points and improve maintenance efficiency.
  • Hot – Swap Function Ensures Continuous Production: It supports hot – swap operations in the Triconex Tricon system. When a fault occurs, maintenance personnel can replace the module without shutting down the entire safety system, which significantly shortens maintenance time and minimizes production losses caused by system downtime.
  • High Network Security Meets Industrial Security Needs: The module has obtained Achilles Level 1 cyber security certification. It adopts a multi – layer security design to prevent unauthorized access and malicious data tampering during signal transmission, ensuring the integrity and confidentiality of industrial control data.
• Application Scenarios
  • Oil and Gas Industry: It is widely used in emergency shutdown systems and fire and gas systems of onshore and offshore drilling platforms. It collects signals from pipeline pressure sensors and gas concentration detectors. When abnormal conditions such as pipeline overpressure or gas leakage are detected, it quickly transmits signals to trigger emergency shutdown procedures and start fire – fighting equipment, avoiding serious accidents such as explosions.
  • Nuclear Power Industry: It is applied to the auxiliary control systems of nuclear power plants that have obtained nuclear 1E certification. It collects status signals from key equipment such as reactor cooling system sensors. It ensures that the system can promptly respond to equipment abnormalities, which is crucial for the safe and stable operation of nuclear power plants.
  • Petrochemical Industry: It is installed in the safety interlock systems of chemical reactors and distillation towers. It collects signals from temperature and pressure sensors on the equipment. When the reaction temperature or pressure exceeds the safe threshold, it sends signals to the controller in a timely manner to cut off the feeding or heating system, preventing uncontrollable chemical reactions and material leakage.
  • Thermal Power Industry: It is integrated into the turbine control and protection systems of thermal power plants. It collects signals from turbine overspeed sensors and boiler safety valve position switches. When the turbine operates abnormally, it quickly feeds back fault information, allowing the system to adjust parameters or shut down the unit in time to avoid equipment damage and large – scale power outages.
  • Marine Industry: With marine certification, it is used in the safety control systems of marine power systems and cargo handling equipment. It collects status signals from marine engines and cargo hold pressure sensors, ensuring the safe operation of ships during navigation and protecting the safety of the ship, crew and cargo.
