    • Storage Temperature: -55°C to 85°C, ensuring performance stability during long-term storage and transportation
    • Humidity Resistance: Operates stably in 5% to 95% non-condensing humidity environments, avoiding malfunctions caused by moisture corrosion in humid industrial settings
    • Vibration Resistance: Withstands 2 g vibration in the frequency range of 10 Hz to 500 Hz, suitable for installation on equipment with mechanical vibration such as offshore platforms and pump stations
• Functional Features
  • Triple Modular Redundancy for Maximum Fault Tolerance: The TMR architecture enables three independent circuit paths to process and output control signals simultaneously. A majority voting mechanism is used to determine the final output state. Even if one or two circuit paths fail, the module can still maintain normal output, completely eliminating the impact of single-point or dual-point faults on the safety system.
  • High-Density Output and Flexible Configuration: With 32 digital output channels, the module meets the multi-point control needs of large-scale industrial systems, reducing the number of modules required and lowering system integration costs. The support for both NO and NC contact configurations allows it to adapt to different on-site wiring requirements without replacing hardware.
  • Strong Isolation and Anti-Interference Capability: The high-voltage isolation design between channels and between channels and ground effectively suppresses electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial environments. It prevents signal crosstalk and ensures stable output signals even in complex electrical environments with multiple high-power equipment running.
  • Comprehensive Diagnostic and Fault Indication: The module has built-in self-diagnostic functions that continuously monitor the status of each output channel, including contact welding, open circuits, and power supply abnormalities. Real-time fault information is transmitted to the upper controller, and the front-panel status indicators clearly display the operating status of the module and each channel, facilitating quick fault location and maintenance by on-site personnel.
  • Seamless System Compatibility and Hot-Swap Support: The module is fully compatible with Triconex Tricon and Trident series controllers, supporting plug-and-play integration without modifying system parameters. It also supports hot-swap operation, allowing maintenance personnel to replace the module online without shutting down the entire safety system, minimizing production downtime 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 oil transmission pipelines. It controls solenoid valves and emergency shut-off valves to cut off oil and gas transmission paths in a timely manner when abnormal pressure, gas leakage, or fire is detected, preventing explosions and large-scale leakage accidents.
  • Petrochemical Industry: Installed in safety interlock systems of chemical reactors, distillation towers, and storage tanks. It drives alarm indicators and emergency shutdown actuators to respond to over-temperature, over-pressure, and material leakage faults during chemical reactions, avoiding violent reactions and toxic substance leakage.
  • Power Generation Industry: Applied in safety control systems of thermal power plants, nuclear power plant auxiliary facilities, and wind farms. It controls the shutdown of boilers, steam turbines, and generator sets when equipment malfunctions such as over-speed and high-temperature are detected, ensuring the safe operation of power generation equipment and preventing power grid accidents.
  • Metallurgical Industry: Integrated into the safety control systems of blast furnaces, steelmaking converters, and continuous casting equipment. It controls cooling water valves and emergency stop devices to adjust the smelting process in real time when furnace temperature or pressure exceeds the safe range, protecting furnace linings and avoiding equipment damage.
  • Pharmaceutical Industry: Used in safety interlock systems of pharmaceutical production lines, especially in high-temperature sterilization, vacuum drying, and drug filling processes. It controls the operation of sterilizers and filling machines to ensure that each production link complies with GMP standards, avoiding batch drug quality problems caused by process parameter deviations.
