Triconex 4000189-560 32-Channel Triple Modular Redundancy Digital Input Module

Description

• • Physical Parameters
    • Dimensions: It adopts a compact structural design with dimensions of 175 mm × 120 mm × 50 mm. This size is fully compatible with the Triconex standard chassis, which helps save installation space in the control cabinet and simplifies the overall layout of the system.
    • Weight: The net weight is approximately 1.4 kg. The all-metal shell enhances the module’s resistance to mechanical collision and vibration, ensuring structural stability during transportation, installation, and long-term operation.
    • Connector Type: It is equipped with a 50-pin detachable terminal block. This design simplifies on-site wiring work, and during later maintenance, it allows quick disassembly and assembly without damaging the wiring, improving maintenance efficiency.
  • Environmental Parameters
    • Operating Temperature: It can operate stably within the range of -40°C to 70°C, adapting to various harsh temperature environments, including cold outdoor industrial sites and high-temperature chemical workshops.
    • Storage Temperature: The safe storage temperature range is -55°C to 85°C. This wide range ensures that the module will not suffer performance degradation due to extreme temperatures during long-term storage or long-distance transportation.
    • Humidity Resistance: It can work normally in an environment with a relative humidity of 5% – 95% without condensation. This makes it suitable for humid industrial environments such as coastal oil and gas platforms and water treatment plants.
    • Vibration Resistance: It can withstand 2 g vibration in the frequency range of 10 Hz – 500 Hz, and can be stably installed on equipment with continuous vibration, such as industrial pumps, compressors, and mechanical transmission devices.
• Functional Features
  • Triple Modular Redundancy Ensures Fault Tolerance: Three independent and identical circuit paths simultaneously collect and process signals from each input channel. The upper controller adopts a two-out-of-three voting mechanism to determine the final valid signal. Even if one or two circuit paths break down, the module can still output accurate data, completely eliminating the impact of single-point faults on the system.
  • Hot-Swap Function Minimizes Downtime: The module supports hot-swap operations in the Triconex system. When a fault occurs, maintenance personnel can replace the faulty module without shutting down the entire safety system. This function significantly shortens maintenance time, reduces production losses caused by system outages, and improves the operational availability of the production line.
  • Comprehensive Diagnostic Capabilities Simplify Troubleshooting: Each input channel is equipped with an independent diagnostic circuit that continuously monitors the channel’s wiring status and the working state of connected sensors. When faults such as open circuits, short circuits, or poor contact occur, the module immediately uploads detailed fault information to the upper system and activates the corresponding indicator lights on the panel, enabling maintenance personnel to quickly locate and resolve problems.
  • Strong System Compatibility Facilitates Integration: It can be seamlessly compatible with Triconex Tricon and Tricon CX series controllers. During integration, plug-and-play can be achieved without modifying the core control program. It also matches the standard terminal blocks and connecting cables of the Triconex system, reducing the difficulty of system installation and debugging.
  • Cyber Security Protection Safeguards Data Integrity: The module has obtained Achilles Level 1 cyber security certification. It adopts a multi-layered security design to prevent unauthorized access and malicious data tampering during the signal transmission process, ensuring the confidentiality and integrity of industrial control data in complex network environments.
• Application Scenarios
  • Oil and Gas Industry: It is widely used in emergency shutdown systems and fire and gas systems of offshore drilling platforms and onshore oil and gas transmission pipelines. It collects signals from gas concentration detectors and pipeline pressure switches. Once gas leakage or pipeline overpressure is detected, it quickly transmits signals to the controller to trigger pipeline shutdown and fire-fighting equipment startup, avoiding serious accidents such as explosions and large-scale oil spills.
  • Petrochemical Industry: It is installed in the safety interlock systems of chemical reactors, distillation towers, and storage tanks. It collects signals from temperature sensors and liquid level switches in production equipment. When the reaction temperature or material level exceeds the preset safety threshold, it promptly sends data to the upper system to cut off the feeding or heating system, preventing dangerous situations such as material leakage and uncontrollable chemical reactions.
  • Power Generation Industry: It is applied to the safety control systems of thermal power plants, nuclear power plant auxiliary equipment, and hydropower stations. It collects signals from steam turbine overspeed sensors and boiler safety valve position switches. When the unit operates abnormally, it quickly feeds back fault information, enabling the system to adjust parameters or shut down the unit in time to protect the safety of key power generation equipment and avoid large-scale power outages.
  • Metallurgical Industry: It is integrated into the safety control systems of blast furnaces, converter equipment, and continuous casting production lines. 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 immediately sends an alarm signal to the controller, which then adjusts the production process to prevent equipment damage caused by overheating and ensure the stability of the smelting process.
  • Marine Industry: As a marine-certified module, it is used in the safety control systems of marine power systems and cargo handling equipment. It collects signals from marine engine status sensors and cargo hold pressure switches. It ensures the safe operation of marine equipment during navigation, preventing equipment failures from endangering the safety of the ship and crew.
