Power Line Carrier (PLC) Module
This product is a data transmission module that uses the principle of multi-carrier modulation orthogonal frequency division multiplexing technology to perform high-speed and long-distance serial transmission of parallel data by frequency division multiplexing to realize power line carrier communication.
It can be widely used in inconvenient wiring or long-distance, high-speed, multi-node data communication, military, power, chemical, railway, petroleum and other industries with high security requirements, it is also ideal for environments that require upgrades and inadequate communication lines.

1. The communication distance is far: the transmission of the private network power line exceeds 10Km.
2. Strong anti-strong interference.
3. Transparent transmission of data.
4. AES encryption and security certification.
5. Functional diversity:
Signal modulation adaptive function: OFDM adaptive carrier mapping function, each receiving station automatically analyzes the signal quality of each subcarrier of the received signal, and adopts the optimal modulation method accordingly, thereby improving and ensuring communication quality.
Automatic networking: no need to configure IP address and MAC address, the whole process does not require human intervention.
Automatic routing function (long range does not include this feature): Automatically optimize routing paths without relying on network topology and historical data to minimize data collision and congestion.
Automatic network access function: You can increase or decrease the number of nodes at any time on a working network. Without manual configuration, the device will automatically join the network to send data.
Automatic gain function: It can automatically adjust the signal-to-noise ratio and signal strength according to the interference environment of the power line, achieve minimum attenuation and optimal reception of useful signals, minimize noise interference from power lines and reduce PLC power consumption.
Automatic relay function (long range does not include this feature): It can automatically collect the address of the adjacent station, thereby automatically forming the routing table of the adjacent station; when one or more communication failures occur, the nearest station will automatically forward the information that needs to be forwarded by the fault point. This skips the point of failure and re-creates the new route automatically.
Health diagnosis function: The system automatically analyzes the signals of the body and nodes to automatically judge whether the device is good or bad.
Automatic recovery function: The device does not have heartbeat data at the specified time, and automatically restarts and accesses the unit.
