KQ-130E Power Line Transceivers 9Pin High-Performance Carrier Data Transceiver Module Power Line Carrier Communication
Product Description
Single row 9-pin small volume high-performance carrier data transceiver module. It is specially designed and designed for reliable data transmission under 0V-220V AC and DC and no power supply environment (such as pipeline and earth, one signal line and earth, two signal lines, 12V AC and DC power cord, etc.) Developed a carrier module with high cost performance. 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 dedicated line). The actual transmission rate of 100BPS or 400BPS is adjusted by the user. The KQ-130E carrier module includes many complicated peripheral circuits such as carrier drive, coupling, filtering, lightning protection and so on. The user only needs to provide a single 5V power supply. After the two signal lines (TX, RX) are connected to the single-chip microcomputer, they are directly connected to 220V through the two AC terminals of the module (regardless of the live wire and the neutral wire), so as to realize the communication like 485 through the power carrier. Fully transparent way to send and receive data.

Installation Instructions
Pin description
1P—AC: Live wire (or neutral wire) with 220V AC voltage 2P—AC: 220V AC voltage neutral wire (or live wire) 3P—+12V: +12V power supply (300mA) has no current when receiving, 15V is the highest voltage sent. 4P—GND: Digital circuit ground wire 5P—+5V: +5V power supply 12mA, the minimum working voltage can reach 3.3V but not recommended 6P—RX: TTL level, carrier data input, connected to TXD of MCU 7P—TX: TTL level, carrier data output, connected to RXD of single-chip microcomputer 8P—MODE: Mode selection, floating or connected to 5V for high level, grounding for low level 9P—NC/RST: The reset pin (active low) is used when switching modes frequently during work. No need for this function, the pin should be left floating
