Description
Customizable KQ-132K 485 Interface No External Component PLC Fast Power Line Carrier Data Transmission Module
Product Description
KQ-132K series performance
1. Integrated KQ-330K2 module and peripheral circuit carrier board, no need for other coupling components, can be directly connected to the highest 275V AC and DC power supply. 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 carrier rate of 1200 BPS/300 BPS is set by the user.
3. The maximum length of one frame continuous transmission is ≤ 252 bytes, and the module will not send more data.
4. Receiving sensitivity ≤1mV
5. Out-of-band rejection ≥ 60 dB
6. Bandwidth ≤10 KHZ
7. Insulation resistance 500V ≥ 500MΩ
8. Power supply: DC +5V Receive: ≤12mA When transmitting ≤300mA
9. Power frequency insulation withstand voltage: AC to GND between 3000V 1min test without breakdown, no leakage current.
10. Anti-lightning strike: In-board TVS tube protection, from PCB board wiring selection to component selection, all are designed according to wide temperature, high withstand voltage and high pressure impact resistance.
