KQ-130F is a single row 9-pin small size high-performance zero 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 diode protection against thunder 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. Working Frequency: 120-135KHZ Connector Baud Rate: 9600bps Actual Baud Rate: 100bps One Frame Continuous Send Max. Length: less than or equal to 252 bytes (user defines from 1 to 252, module will not send redundant data) Receive Sensitivity: less than or equal to 1mV Out-of-band Rejection Ability: greater or equal to 60dB Band Width: less than or equal to 10 KHZ Insulation Resistance: 500V greater or equal to 500M ohm Power Supply: DC and5V(receiving: less than or equal to 11mA sending: less than or equal to 230mA) Frequency Insulation Withstand Voltage: AC to GND 3000V (1min test no breakdown, nor current leak) Operating Temperature: -25 Celsius-70 Celsius Operating Humidity: less than or equal to 90 percent Weight: 30g(.) Wiring: 1P- -AC: 220V live wire (or neutral wire) 2P- -AC: 220V neutral wire (or live wire) 3P- -and5V: and5V sending power supply(210mA), if only receiving data, can be disconnected to reducing power consumption 4P- -GND: Digital circuit ground 5P- -and5V: and5V 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 or : Reset pin(low level effective), for frequent switching modes. No connection if do not use this function.
