Triconex 4000189-520 32-channel Triple Modular Redundancy Digital Input Module

Description

• • Physical Parameters
    • Structural Dimensions: It adopts a compact structural design with dimensions of 175 mm × 120 mm × 50 mm, which is fully compatible with the Triconex standard system chassis and saves the installation space in the control cabinet.
    • Weight: The net weight is about 1.4 kg. The rugged metal shell not only enhances the mechanical strength of the module but also provides good heat dissipation performance.
    • Connector Type: It is equipped with a 50 – pin detachable terminal block, which simplifies on – site wiring operations and facilitates quick disassembly and assembly during maintenance.
  • Environmental Parameters
    • Operating Temperature: It can operate stably in the range of – 40°C to 70°C, which can adapt to the extreme temperature changes of outdoor industrial sites and indoor control rooms.
    • Storage Temperature: It can be stored safely in the environment of – 55°C to 85°C, ensuring no performance degradation during long – distance transportation and long – term storage.
    • Humidity Resistance: It can work normally in an environment with a relative humidity of 5% – 95% without condensation, avoiding component corrosion and short circuits caused by humid air in coastal and chemical industrial environments.
    • Vibration Resistance: It can withstand 2 g vibration in the frequency range of 10 Hz – 500 Hz, which is suitable for installation on equipment with continuous vibration such as compressors and pumps.
• Functional Features
  • Triple Modular Redundancy Ensures Fault Tolerance: Three independent circuit paths simultaneously collect and verify signals from each input channel. The upper – level controller uses a two – out – of – three voting mechanism to determine the final effective signal. Even if one or two circuit paths fail, the module can still output accurate data, completely eliminating the risk of system misoperation caused by single – point faults.
  • Rapid Signal Response Supports Timely Interlocking: The fast response time of less than 3 ms allows the module to quickly capture transient abnormal signals such as sudden equipment failures. This enables the safety system to trigger interlock measures such as emergency shutdown in a short time, preventing the expansion of minor faults into major safety accidents.
  • Hot – Swap Function Reduces Downtime: The module supports hot – swap operation in the Triconex system. Maintenance personnel can replace the faulty module without shutting down the entire safety system. This function greatly shortens the maintenance time of the system, reduces production losses caused by system shutdown, and improves the overall availability of the production line.
  • Comprehensive Diagnostics Simplify Maintenance: Each input channel is equipped with an independent diagnostic circuit, which can real – time monitor the wiring state of the channel and the working state of the connected sensors. When faults such as open circuits and poor contact occur, the fault information will be immediately uploaded to the upper – level system, and the corresponding indicator lights on the module panel will be on, which helps maintenance personnel quickly locate and troubleshoot.
  • Strong Compatibility Facilitates System Integration: It can be perfectly compatible with Triconex Tricon and Tricon CX series controllers. It can realize plug – and – play without modifying the core program of the system during integration. It can also match the standard terminal blocks of the Triconex system, simplifying the system debugging and installation process.
• Application Scenarios
  • Oil and Gas Industry: It is deployed in emergency shutdown systems and fire and gas systems of offshore drilling platforms and on – shore oil transmission pipelines. It collects signals from gas detectors and pipeline pressure switches. When gas leakage or overpressure is detected, it can quickly transmit signals to the controller to trigger pipeline shutdown and fire – fighting system startup, preventing explosions and other major accidents.
  • Petrochemical Industry: It is installed in the safety interlock systems of chemical reactors and distillation towers. It collects signals from temperature limit switches and liquid level sensors in the reaction kettle. When the reaction temperature or material level exceeds the safety threshold, it can send data to the upper – level system in time to cut off the feeding system and avoid dangerous reactions such as material leakage and explosion.
  • Power Generation Industry: It is applied to the safety control systems of thermal power plants and nuclear power plant auxiliary equipment. It collects signals from steam turbine overspeed sensors and boiler safety valve position switches. When the unit has abnormal conditions, it can quickly transmit fault signals to ensure that the system adjusts the equipment state or shuts down the unit in time to protect the safety of key power generation equipment.
  • Metallurgical Industry: It is integrated into the safety control systems of blast furnaces and continuous casting equipment. It collects signals from furnace temperature sensors and cooling water flow switches. When the furnace temperature is too high or the cooling water flow is insufficient, it can immediately send signals to the controller to adjust the production parameters, avoiding equipment damage caused by overheating.
  • Pharmaceutical Industry: It is used in the automatic control systems of pharmaceutical filling and high – temperature sterilization production lines. It collects signals from photoelectric sensors and pressure switches on the production line. It ensures that each link of drug production meets GMP standards, avoiding batch drug quality problems caused by abnormal equipment operation in the production process.
