2x Kq-130f Power Line Carrier Module / No External Components Required f54 1. The carrier board that integrates the KQ-330F module and peripheral circuits does not require other coupling components, and can be directly connected to 220V AC power. The external dimension is 53x38x17 mm (LxDxH), and the single row of pins leads out. 1 and 2 pins are connected to 220V AC power supply without direction (1 pin, 2 pin spacing 2X0.1 inches), 2 feet and 3 feet are 1.1 inches apart, and the rest of the 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. 3. The maximum length of one frame of continuous transmission is 252 bytes, the length of one frame of continuous transmission is defined by the user from 1 to 252, and the module will not send redundant data 4. Receiving sensitivity 1mV 5. Out-of-band rejection capability 60 dB Bandwidth 10 KHZ Insulation resistance 500V 500M Power supply: DC +5V when receiving: 11mA when sending 230mA Power frequency insulation withstand voltage: 3000V 1min test between AC and GND has no breakdown and no leakage current. Anti- strike: tube protection inside the board, from PCB board wiring material selection to component material selection, are designed according to wide temperature, high pressure resistance, and high pressure shock resistance. Working temperature: -25~70 Humidity90% KQ-130F power carrier module does not need any peripheral devices, as long as it provides a 5V power supply, it can be used. The transmission power supply is pin. If the user needs bidirectional transmission, two 5V pins can be connected in parallel. All modules of our company support point-to-point, point-to-multipoint networking communication mode, and control of multipoint data through polling. color:As shown Material:PCB Package Contents: 2 x KQ-330F module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
