Description
    • Physical and Environmental Parameters
      • Its physical dimensions are 175 mm in length, 100 mm in width and 50 mm in height, and it weighs 0.5 kg. It fits into Tricon standard rack slots and supports DIN rail installation.
      • It can work stably in an environment with a temperature range of – 40°C to + 70°C and a non – condensing humidity range of 0 – 95%. Some models have an IP67 protection rating, which can resist dust and water intrusion in harsh industrial sites.
  • Functional Features
    • Triple Modular Redundancy Ensures Communication Continuity
      • The triple modular redundancy architecture is the core of its high reliability. Three independent communication channels process data simultaneously and adopt a majority voting mechanism. When a single channel malfunctions, the other two normal channels can maintain continuous data transmission, avoiding communication interruptions that may lead to industrial safety accidents.
      • The galvanic isolation design and anti – corrosion coating on the module surface, along with gold – plated contacts, enhance its resistance to electrical surges and corrosion, which prolongs its service life in complex industrial environments.
    • Multi – protocol Compatibility and Strong Integration
      • The integration of multiple mainstream industrial communication protocols allows the module to be flexibly connected with different types of industrial equipment and systems from various manufacturers. For example, it can connect photovoltaic inverters via Modbus and communicate with PLC controllers through EtherNet/IP.
      • The embedded relevant functional components enable it to be smoothly integrated with SCADA systems and other industrial management platforms, realizing real – time monitoring and control of data and improving the overall operational efficiency of the industrial control system.
    • Hot – swap and Intelligent Diagnostic Capabilities
      • It supports hot – swap operation. Maintenance personnel can replace faulty modules online without shutting down the entire control system, which minimizes production downtime caused by equipment maintenance.
      • It can conduct real – time monitoring of communication links, power voltage and module temperature. It can promptly detect communication interruptions and protocol configuration errors, and send alarm signals through LED indicators on the module and remote diagnostic interfaces of the system software to help staff quickly locate and troubleshoot faults.
  • Application Scenarios
    • Oil and Gas Industry
      • In offshore drilling platforms and onshore refineries, it connects the emergency shutdown system controller to the main distributed control system. It realizes real – time data transmission between the two systems, which facilitates the central control room to monitor the operation status of equipment and record key data, and ensures the immediate execution of emergency shutdown instructions when dangerous situations such as oil and gas leakage occur.
      • In long – distance oil and gas transmission pipelines, it establishes communication links between on – site pressure and flow sensors and the central control system. It ensures that the central control room can timely obtain pipeline operation data and adjust parameters in a timely manner to prevent pipeline explosion or leakage accidents.
    • Chemical and Power Industry
      • In chemical plants, it is applied to the communication of burner management systems and fire and gas systems. It realizes data exchange between the burner controller and the human – machine interface station to ensure the safe start – up and shutdown of burners. It also connects fire and gas detectors with the central control room to ensure that fire and gas leakage alarms are transmitted to the control center immediately.
      • In thermal power plants, it connects the turbine control system with speed sensors and other equipment. It transmits the operating state data of the turbine to the central control system in real time, which helps to protect key rotating equipment and avoid serious equipment damage due to abnormal speed.
    • Other High – risk Industrial Fields
      • In nuclear power plants, it is used in the communication of auxiliary safety control systems. It connects the monitoring equipment of nuclear reactor auxiliary systems with the central safety control platform to ensure the stable transmission of safety – related data and provide a guarantee for the safe operation of nuclear power units.
      • In large – scale pharmaceutical production bases with strict process control requirements, it realizes data interaction between the production process control system and the quality monitoring system, ensuring that the production parameters are monitored and recorded in real time to maintain the stability of product quality.
