Triconex 4000187-350 32-channel Triple Modular Redundancy Digital Input Module

Description

• • Environmental Adaptability Parameters
    • Temperature Range: It can operate stably in the temperature range of – 20°C to 70°C, and the storage temperature range is – 40°C to 85°C, which can adapt to the temperature changes of various industrial working conditions.
    • Other Environmental Indicators: It can work normally in an environment with a relative humidity of 5% to 95% under non – condensing conditions. It has a vibration resistance of 2 g at 10 – 500 Hz, which can resist the vibration impact generated by industrial equipment during operation.
  • Structural and Diagnostic Parameters
    • Channel and Connector: It has 32 physical channels, which can realize 32 logical safety inputs through three – channel redundant sampling. It is equipped with a 37 – pin DIN connector, and the structure is stable to avoid poor contact.
    • Diagnostic Capability: The diagnostic coverage rate exceeds 99%, which can effectively identify faults such as open circuits, short circuits, and channel inconsistencies, and promptly feed back fault information to the main control system.
• Functional Features
  • Triple Modular Redundancy Ensures Signal Reliability: Each on – site switching signal is read by three completely isolated input circuits at the same time, and the main processor performs a two – out – of – three consistency check. Any single – channel fault can be automatically identified and isolated, which ensures that the safety logic will not be affected by wrong signals and avoids false shutdowns or failures to act due to unreliable input signals.
  • Flexible Input Configuration Adapts to Diverse On – site Needs: The input type can be flexibly configured as sourcing or sinking according to on – site wiring requirements. It does not need to replace the module for different wiring methods, which reduces the difficulty of on – site installation and debugging and improves the efficiency of system construction.
  • High Diagnostic Coverage Facilitates Maintenance: With a diagnostic coverage rate of more than 99%, it can quickly detect various common faults such as line disconnection and channel inconsistency. Timely fault feedback enables maintenance personnel to locate and solve problems quickly, reducing the downtime of the safety system caused by module faults.
  • Strong Compatibility Integrates into Existing Systems: It is a core component of the Tricon v10 platform and can be perfectly integrated into the Tricon v10 fault – tolerant safety control system. When used with Triconex original terminal blocks, it can avoid problems such as ground loops and common – mode interference, ensuring the stable operation of the entire system.
• Application Scenarios
  • Refining and Petrochemical Industry: It is used in the emergency shutdown systems of refining equipment. It collects key interlock signals such as high compressor shaft vibration alarms and low lubricating oil pressure. When abnormal signals are detected, it can quickly transmit the signals to the control system to trigger the emergency shutdown mechanism and avoid equipment damage and safety accidents.
  • Offshore Oil and Gas Industry: It serves as the input front – end of the fire and gas system on offshore platforms. It receives status signals from combustible gas detectors, manual alarm stations, and fire pumps. It ensures that the safety system can timely grasp the on – site safety situation and quickly start the fire – fighting and emergency measures when dangers such as gas leakage occur.
  • Power Generation Industry: It is applied to the safety control systems of thermal power plants and nuclear power plant auxiliary facilities. It collects status signals of key equipment such as boiler safety valves and generator set temperature monitors. It helps the control system monitor the operation status of the equipment in real time and ensures the safe and stable operation of the power generation process.
  • Chemical Industry: It is integrated into the safety interlock system of chemical reactors. It collects signals such as the opening and closing status of feed valves and the leakage of chemical raw materials. When the reaction parameters exceed the safe range, it transmits the fault signal to the main control system in time to cut off the relevant processes and prevent accidents such as reactor explosions and chemical leaks.
