KQ-130F Power Line Carrier Module for 220VAC Power Line Long Distance Data Communication Features: KQ-130F is a single row 9-pin small size high-performance carrier data transceiver module. Designed for on 220V AC, strong interference, strong attenuation and long distance required environment, reliable data transmission. A frame continuous send maximum length is 252 bytes or less, from 1 to 252 defined by the user, and the module will not send redundant data. TVS diode protection against lightning stroke, the PCB wiring and components selection are all designed for wide temperature and high voltage resistance. Suitable for meter reading, street light, intelligent household, fire fighting, building control and other applications that need power to send data. 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) 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) 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.
