KQ-130485K is a single-row, 9-pin, small-sized, high-performance, high-speed carrier data transceiver module based on a self-developed carrier chip. It adds a 485 chip and a fully transparent program embedded in PLC and other equipment. It is specially designed for reliable transmission of high-speed data in 0V-220V AC and DC, and in environments without power supply (such as pipelines and the ground, one signal line and the ground, two signal lines, 12V AC and DC power lines, etc.). And developed a cost-effective carrier module. It is suitable for industrial control, railway, community intelligence, smart home, building control and other application fields that require carrier to transmit data. The transmission distance can reach 2.5Km (power line). The actual carrier rate can reach 2400BPS.
The KQ-130485K carrier module includes many complex peripheral circuits such as carrier drive, coupling, filtering, and lightning protection. The user only needs to provide 12V power supply. After two 485 signal lines (485 +, 485 -) are connected to the 485 bus, they are directly connected to 220V through the two AC ends of the module (regardless of the live line and neutral line), and PLC and other equipment are directly connected through 485 The KQ-130485K carrier module realizes the fully transparent way of power line carrier to send and receive data. Fully transparent transmission between PLCs can be achieved.
