KQ-130F is a single-row 9-pin small-volume high-performance zero-crossing carrier data transceiver module. It is a cost-effective carrier module specially designed and developed for reliable transmission of data under 220V AC, strong interference, strong attenuation, and long-distance requirements. Suitable for meter reading, street lighting, smart home, fire protection, building control and other applications where power lines are required to transmit data.KQ-130F series performance:
1. Integrated KQ-330F module and peripheral circuit carrier board, no need for other coupling components, directly connected to 220V AC. The outer dimensions are 53×38×17 mm (L×D×H), and the single row of pins is led out (see the figure below). The pins are connected to the 220V AC power supply without direction (1 pin, 2 pin spacing 2X0.1 inches). 2 feet, 3 feet are 1.1 inches apart, and the remaining feet are 0.1 inches apart.
2. The working frequency is 120~135KHZ, and the interface baud rate is 9600bps. The actual baud rate is 100bps, 250 bytes of buffer.
3. Temperature range: -25 ° C ~ +70 ° C Humidity ≤ 90%
4. Power supply: DC +5V Receive: ≤11mA When transmitting: ≤300mAPin Description:
1P--AC: Firewire (or neutral) of 220V AC voltage
2P--AC: Zero line (or fire line) of 220V AC voltage
3P--+5V: +5V transmit power (260mA), if the data can be suspended, the power consumption can be suspended.
4P--GND: Digital circuit ground
5P--+5V: +5V working power 11mA
6P--RX: TTL level, carrier data input, connected to the TXD of the single chip, high resistance input can not be left floating
7P--TX: TTL level, carrier data out, connected to the RXD of the microcontroller
8P--MODE: mode selection, floating or connected to 5V is high level, grounding is low level
9P--NC/RST: The reset pin (active low) is only used when switching modes frequently during operation. Need this function, the pin should be left floating
Package includes:
1 x Data Transceiver Module
