Core function
Achieving physical connection and power supply
It reliably connects the RFO810 optical module, the HN800 control bus, and the power supply together, forming a complete optical signal conversion and transmission node. Without it, the RFO810 module would not be able to obtain power or connect to the system.
Key Value: Supports hardware redundancy to ensure system high availability
This is the most prominent value of RMU811. Its design allows for the installation of two RFO810 modules on a single base, forming a redundant pair. When an optical fiber link or module fails, the other can seamlessly take over communication, which is crucial for process industries such as power plants and chemical plants that require continuous operation 24 hours a day. It can prevent production interruptions or out-of-control situations caused by single-point failures.
Final Goal: Achieve stable communication over long distances and with anti-interference capabilities
When the RFO810 is installed on the RMU811 and connected to the system, it can fully utilize the optical fiber communication capabilities of the RFO810, expanding the transmission distance of the original bus (such as HN800/CW800) from several hundred meters to up to 3 kilometers. At the same time, the anti-electromagnetic interference characteristic of the optical fiber can ensure stable and reliable data transmission even in industrial sites with dense motors and frequency converters.
