    • Weight: 1.5 kg, with a rugged metal housing that enhances resistance to mechanical vibration and physical impact
    • Connector Type: Equipped with a 50-pin D-sub connector and a removable terminal block, simplifying on-site wiring and maintenance operations
  • Environmental Parameters
    • Operating Temperature: -40°C to 70°C, adapting to extreme temperature conditions in indoor control rooms and outdoor industrial sites
    • Storage Temperature: -55°C to 85°C, ensuring performance stability during long-term storage and transportation
    • Humidity Resistance: Operates stably in 5%–95% non-condensing humidity environments, avoiding component corrosion in humid industrial settings
    • Vibration Resistance: Withstands 2 g vibration in the frequency range of 10 Hz–500 Hz, suitable for installation on equipment with continuous vibration such as compressors and pumps
• Functional Features
  • Triple Modular Redundancy for Maximum Reliability: Three independent circuit paths sample each input signal simultaneously, and the controller executes a majority voting mechanism to confirm the valid signal state. Even if one or two paths fail, the module can still output accurate data, completely eliminating the risk of system misoperation caused by single-point faults.
  • High-Speed Signal Response for Critical Scenarios: The 2 ms ultra-fast response time enables the module to capture transient fault signals from high-speed rotating equipment (such as turbine overspeed alarms) in real time, ensuring the safety system can trigger interlock protection measures before dangerous conditions escalate.
  • Comprehensive Self-Diagnostic Capabilities: The built-in diagnostic current function continuously monitors the integrity of field wiring, detecting open-circuit faults within seconds and transmitting fault information to the upper system. Front-panel status indicators clearly display the operating state of each channel, facilitating quick fault location by maintenance personnel.
  • Flexible Input Configuration and System Compatibility: The module supports both sourcing and sinking input modes without hardware modification, adapting to different on-site wiring requirements. It is fully compatible with Triconex Tricon and Trident series controllers, realizing plug-and-play integration without modifying system parameters.
  • Hot-Swap Support to Minimize Downtime: The hot-swappable design allows maintenance personnel to replace the module online without shutting down the entire safety system, significantly reducing production downtime caused by equipment maintenance and improving system availability.
• Application Scenarios
  • Oil and Gas Industry: Deployed in emergency shutdown systems (ESD) and fire and gas detection systems (F&G) on offshore drilling platforms and onshore pipelines. It collects signals from emergency stop buttons, gas detectors, and pipeline pressure switches, ensuring the system can quickly trigger shutdown procedures when gas leakage or overpressure is detected to prevent explosions.
  • Petrochemical Industry: Installed in the safety interlock systems of chemical reactors, distillation towers, and storage tanks. It captures signals from level switches, temperature limit switches, and valve position sensors, providing real-time data for the controller to adjust reaction parameters and avoid violent chemical reactions or material leakage.
  • Nuclear Power and Thermal Power Industry: Applied in the safety control systems of nuclear power plant auxiliary equipment and thermal power plant boiler systems. It collects signals from turbine overspeed sensors, boiler safety valve position switches, and coolant flow switches, ensuring the system can respond to equipment faults in time to protect the safe operation of power generation units.
  • Metallurgical Industry: Integrated into the 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 or material overflow.
  • Pharmaceutical Industry: Used in the automated production lines of drug manufacturing, especially in high-temperature sterilization and precision filling processes. 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.
