Triconex 4116 16-Channel Triple Modular Redundancy Digital Input Module

Description

• • Physical Parameters
    • Installation Type: Standard rack-mounted design, fully compatible with Triconex Tricon series chassis, supports hot-swap without additional tools
    • Structural Dimensions: 175 mm × 120 mm × 50 mm, compact size to save control cabinet installation space
    • Connector Type: 50-pin detachable terminal block, with anti-loosening design to adapt to industrial site vibration
    • Status Indicators: Each channel is equipped with independent LED indicators to display signal input status and fault alarms
  • Environmental Parameters
    • Operating Temperature: -40°C to 70°C, adapts to extreme temperature environments such as outdoor oil fields and high-temperature chemical workshops
    • Storage Temperature: -55°C to 85°C, ensures stable performance during long-term storage and transportation
    • Humidity Adaptability: 5% to 95% relative humidity (non-condensing), suitable for humid environments such as coastal petrochemical plants
    • Vibration Resistance: Withstands 2 g vibration in the frequency range of 10 Hz to 500 Hz, can be installed near high-vibration equipment such as pumps and compressors
• Functional Features
  • Triple Modular Redundancy Ensures Fault Tolerance: Three independent circuit paths sample each input signal simultaneously, and the controller uses a two-out-of-three voting mechanism to confirm valid signals. Even if one or two paths fail, the module can still output accurate data, completely eliminating the impact of single-point faults on the safety system.
  • Dual Input Type Compatibility Enhances Versatility: Supports both 24 VDC sink/source and dry contact input modes without hardware modification, adapting to different on-site wiring requirements and reducing the need for signal conversion accessories.
  • Comprehensive Self-Diagnostic Capabilities Simplify Maintenance: Built-in diagnostic circuits monitor channel wiring status, power supply stability, and internal component health in real time. When faults such as open circuits, short circuits, or poor contact occur, fault information is uploaded to the upper system immediately, and LED indicators light up to help maintenance personnel quickly locate problems.
  • Hot-Swap Function Minimizes Production Downtime: The module supports hot-swap operation in the Triconex system. Maintenance personnel can replace faulty modules without shutting down the entire safety system, significantly reducing maintenance time and production losses.
  • Strong System Compatibility Facilitates Integration: Seamlessly compatible with Triconex Tricon and Trident series controllers, supports plug-and-play integration without modifying core control programs, and matches Triconex standard terminal blocks and cables to simplify system debugging.
• Application Scenarios
  • Oil and Gas Industry: Deployed in emergency shutdown systems (ESD) and fire and gas detection systems (F&G) of offshore drilling platforms and onshore pipelines. It collects signals from emergency stop buttons, gas detectors, and pipeline pressure switches, triggering emergency shutdown procedures in a timely manner when gas leakage or overpressure is detected to prevent explosions.
  • Petrochemical Industry: Installed in safety interlock systems of chemical reactors, distillation towers, and storage tanks. It captures signals from temperature limit switches, liquid level sensors, and valve position switches, providing real-time data for the controller to adjust reaction parameters and avoid violent chemical reactions or material leakage.
  • Power Generation Industry: Applied to safety control systems of thermal power plants and nuclear power plant auxiliary equipment. It collects signals from steam turbine overspeed sensors, boiler safety valve position switches, and coolant flow switches, ensuring the system responds to equipment faults in time to protect the safe operation of power generation units.
  • Metallurgical Industry: Integrated into safety control systems of blast furnaces, steelmaking converters, and continuous casting equipment. It monitors signals from furnace door position switches, cooling water flow switches, and molten steel level sensors, helping the controller adjust the smelting process and prevent equipment damage caused by overheating.
  • Pharmaceutical Industry: Used in automated production lines for high-temperature sterilization and precision filling. It collects signals from photoelectric switches, bottle-in-place sensors, and pressure limit switches, ensuring each production link complies with GMP standards and avoiding batch drug quality problems caused by process deviations.
