ProSoft MVI56-MDA4 MDA Scientific CM4 Gas Analyzer Master Module

Technical Specifications

  • Mechanical and Backplane Specifications
    • It is compatible with the 1756 backplane, adopts a single – slot design, and can be installed in both local and remote racks of ControlLogix chassis. It is recognized as a standard input and output module by the ControlLogix system and can access the processor memory smoothly.
  • Electrical Parameters
    • The input voltage ranges from 110V AC to 240V AC, and the operating frequency is 50Hz or 60Hz. The maximum power consumption does not exceed 5W, which shows low energy consumption and has little impact on the overall power load of the industrial control system.
  • Communication and Measurement Parameters
    • It supports Modbus RTU and Modbus ASCII communication protocols, is equipped with two RS – 232 communication ports for connecting to CM4 gas analyzers, and an RJ45 serial port for configuration operations.
    • The sampling rate can reach up to 10Hz. For common gases, the measurement range includes 0 – 25% volume for oxygen and 0 – 20000 ppm for carbon monoxide, with a measurement accuracy of ±0.5%.

Description
    • Environmental Parameters
      • The operating temperature ranges from -20°C to 50°C, and the storage temperature is from -40°C to 70°C. It can adapt to the temperature changes of most indoor and outdoor industrial sites.
      • The relative humidity tolerance is 0% to 95% non – condensing, which can operate stably in humid industrial environments such as chemical workshops and water treatment plants.
  • Functional Features
    • Seamless Compatibility and Easy Integration
      • It is perfectly compatible with Rockwell Automation ControlLogix processors and MDA Scientific CM4 gas analyzer networks. The sample ladder logic it provides can be directly used in RSLogix 5000 software, and users can also define data types and controller tags according to actual needs.
      • It can be quickly integrated into the existing ControlLogix control system without overhauling the original hardware structure, which greatly reduces the difficulty and cost of system transformation.
    • Stable and Efficient Data Transmission
      • The 5000 – word dedicated register space ensures sufficient storage space for data exchange between the ControlLogix processor and the CM4 network. The asynchronous data transmission mode avoids mutual interference between the processor’s operation and the network’s data transmission actions.
      • It maintains a stable sampling rate of up to 10Hz, ensuring that the central control system can timely obtain real – time data of gas concentration, and laying a foundation for the rapid adjustment of the production process.
    • Convenient Configuration and Maintenance
      • The module can be configured through a serial connection to a desktop PC, and users can view the database content of the module through this connection. The matching sample ladder logic is fully annotated, which is convenient for technicians to understand and modify when necessary.
      • It can work with RSLogix 5000 software to display module data and operating status through controller tags, allowing maintenance personnel to grasp the module’s working condition in real time.
    • Accurate Gas Data Measurement Support
      • It has high measurement accuracy for key gases. The ±0.5% accuracy can meet the strict requirements of industrial production for gas concentration monitoring, and avoid safety hazards or product quality problems caused by inaccurate data.
  • Application Scenarios
    • Chemical Processing Plants
      • In chemical production processes involving flammable, explosive and toxic gases, the module connects CM4 gas analyzers with the ControlLogix central control system. It monitors the concentrations of harmful gases such as carbon monoxide and toxic volatile organic compounds in production workshops and pipelines in real time. Once the gas concentration exceeds the standard, the system can immediately trigger an alarm and start emergency shutdown procedures to prevent safety accidents such as explosions and poisoning.
    • Oil and Gas Industry
      • In oil refineries and natural gas processing stations, it is used to connect gas analyzers installed in oil storage tanks, pipelines and reaction equipment. It monitors the content of flammable gases such as methane and ethane, and the oxygen content in the inert gas protection system. It ensures that the gas environment in each link meets the safety production standards and guarantees the stable operation of oil and gas processing processes.
    • Environmental Protection and Waste Treatment Facilities
      • In waste incineration plants and sewage treatment plants, it collects data from gas analyzers that detect flue gas emissions. It monitors indicators such as sulfur dioxide, nitrogen oxides and particulate matter concentrations in the exhaust gas. It provides accurate data support for environmental protection compliance detection and helps enterprises adjust the combustion or treatment process to meet national environmental emission standards.
    • Pharmaceutical Manufacturing Plants
      • In the process of pharmaceutical production that requires strict control of the production environment, such as sterile drug synthesis and biological fermentation, the module connects gas analyzers that monitor the content of oxygen, carbon dioxide and other gases in the workshop and reaction vessels. It ensures that the gas composition in the production environment meets the requirements of drug production processes, and guarantees the quality and stability of pharmaceutical products.
    • Power Generation Industry
      • In thermal power plants, it is used to monitor the gas composition in the boiler flue gas. It connects CM4 gas analyzers to the ControlLogix control system to obtain data such as oxygen content and carbon monoxide concentration in real time. It helps operators adjust the ratio of coal to air in the combustion process, improve combustion efficiency, reduce energy consumption and pollutant emissions.
