Features Sending Byte Data: The power line carrier module continuously sends a maximum length of 252 bytes or less in one frame, 1 to 252 are defined by the user, and the module will not send redundant data. Good Reliability: This 220VAC power line carrier module has TVS diode lightning protection, PCB wiring and component selection are designed for wide temperature and high voltage resistance. Professional Design: This power line carrier module is specially designed for 220V AC, strong interference, strong attenuation and environments that require long distance, reliable data transmission. High Performance: KQ-130F power line carrier module is a single-row 9-pin small-sized high-performance carrier data transceiver module, which is easy to use. Scope of Application: This power line long-distance data communication power line carrier module is suitable for applications that require power to send data, such as meter reading, street lights, smart home, fire protection, building control, etc. Specifications: Working Frequency: 120~135KHZ Connector Baud Rate: 9600bps Actual Baud Rate: 100bps One Frame Continuous Send Max. Length:  ≤252 bytes (user defines  from 1 to 252, module will not send redundant data) Receive Sensitivity: ≤1mV Out-of-band Rejection Ability: ≥60dB Band Width: ≤10 KHZ Insulation Resistance: 500V≥500MΩ Power Supply: DC +5V(receiving: ≤11mA; sending: ≤230mA) Frequency Insulation Withstand Voltage: AC to GND 3000V (1min test no breakdown, nor current leak) Operating Temperature: -25℃~70℃ Operating Humidity: ≤90% Size: 5.3*4.5*1cm/2.08*1.77*0.39in Weight: 30g(approx.) Wiring: 1P---AC: 220V live wire (or neutral wire) 2P---AC: 220V neutral wire (or live wire) 3P---+5V: +5V sending power supply(210mA), if only receiving data, can be disconnected to reducing power consumption 4P---GND: Digital circuit ground  5P---+5V: +5V working power supply 11mA 6P---RX: TTL level, carrier data input, connect to TXD of SCM 7P---TX: TTL level, carrier data output, connect to RXD of SCM 8P---MODE: Mode selection, connect to 5V as high level or disconnect, connect to ground as low level 9P---NC/RST: Reset pin(low level effective), for frequent switching modes. No connection if do not use this function. Package Includes: 1 x Power-line Carrier Module Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. Package List
