Function Features

• Dual – way Signal Conversion and Stable Communication

  The module completes the bidirectional conversion between 10 Mbps Ethernet signals and 2 Mbps FBM fieldbus signals accurately and efficiently. This conversion capability solves the signal incompatibility problem between the upper – level control station and the on – site fieldbus modules, ensuring fast and lossless transmission of control commands and on – site data. The built – in high – performance processor enhances data processing speed, enabling real – time response to communication requests and maintaining stable communication links.

• Redundant Configuration for Fault Tolerance

  It operates in paired redundant configurations. When one module malfunctions, the other module in the pair immediately takes over all communication tasks without any interruption to data transmission. This redundant design eliminates single points of failure in the communication link, greatly improving the fault tolerance and reliability of the entire control system, which is crucial for industrial processes that cannot tolerate operational downtime.

• Galvanic Isolation and Strong Anti – interference

  The galvanic isolation design between the Ethernet trunk and the FBM fieldbus effectively isolates electrical noise and interference between the two bus systems. It prevents high – voltage surges or abnormal currents from spreading between different parts of the system, protecting both the module itself and connected fieldbus modules as well as control station components from damage. This feature ensures the integrity of signal transmission even in complex electromagnetic environments with multiple high – power devices.

• Hot – swapping and Easy Maintenance

  The hot – swap function allows operators to remove and replace faulty modules during system operation without turning off the power supply of the entire system. This avoids production losses caused by system shutdowns for maintenance. The compact extruded aluminum housing not only provides good physical protection against collisions and dust but also facilitates installation in limited – space control cabinets, reducing installation and layout difficulties.

Application Scenarios

• Oil and Gas Industry

  It is deployed in oil drilling platforms, oil refineries, and natural gas processing plants. It connects the I/A Series control stations with fieldbus modules that monitor pipeline pressure, flow rate, and valve status. The redundant configuration ensures continuous communication even in harsh marine or refinery environments where equipment is prone to failures. The anti – interference performance resists electromagnetic interference from drilling machinery and pumping equipment, ensuring accurate transmission of key data such as oil and gas flow and pressure, which is essential for safe and efficient extraction and processing.

• Chemical Industry

  It is integrated into chemical production workshops involving reaction kettles, distillation columns, and chemical storage tanks. It enables communication between the central control station and fieldbus modules responsible for measuring temperature, pressure, and chemical concentration. When chemical reactions require precise parameter adjustments, the module ensures that control commands are quickly transmitted to on – site actuators. The galvanic isolation function prevents equipment malfunctions caused by chemical corrosion – induced electrical leaks, safeguarding the stability of continuous chemical production processes.

• Power Generation Industry

  It is widely used in thermal power, nuclear power, and hydropower plants. In thermal power plants, it connects the turbine control system and boiler control system with fieldbus modules for monitoring steam pressure, temperature, and generator load. The redundant communication ensures that the control system can still receive real – time operating data of key equipment in case of module failures, avoiding power outages due to communication interruptions. It adapts to the high – temperature and high – electromagnetic – interference environment near generators and transformers, maintaining reliable data interaction.

• Water and Wastewater Treatment Industry

  It is applied in water purification plants and sewage treatment facilities. It links the central control system to fieldbus modules that control water pumps, dosing valves, and filter equipment. It transmits commands for adjusting water flow rates and chemical dosing amounts, while feeding back real – time water quality data such as turbidity and pH value to the control station. The stable communication ensures the accuracy of water treatment processes, helping to meet water quality standards and improving the efficiency of water resource utilization and sewage purification.

• Pharmaceutical Industry

  It is installed in sterile pharmaceutical production lines and drug packaging workshops. It connects control stations with fieldbus modules that regulate mixing equipment, filling machines, and temperature – controlled storage units. In the drug synthesis process, it ensures that parameters such as temperature and mixing speed are accurately transmitted between the control system and on – site equipment. The reliable communication and stable performance of the module help pharmaceutical production comply with GMP standards, ensuring consistent drug quality and avoiding batch – related quality problems caused by communication errors.
