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.
11. Working temperature-25°C~70°C
12. Humidity≤ 90%
1P—AC
Firewire (or neutral) of 220V AC voltage
2P—AC
Zero line (or fire line) of 220V AC voltage
3P—+12V
+12V power supply (300mA) has no current when receiving, and 15V is the highest voltage sent.
4P-GND
Digital circuit ground
5P-+5V
+5V power supply 11mA, the minimum working voltage can be 3.3V but not recommended
6P-RX
TTL level, carrier data input, connected to the TXD of the single chip or the RD pin of the 485 chip
7P-TX
TTL level, carrier data out, connected to the microcontroller's RXD or 485 chip's DI pin
8P-MODE
485 chip control terminal, connected to 485 chip RE, DE terminal
9P-NC
Pin should be left floating
The jumper next to the coil in the picture selects the actual carrier rate:
Short jumper: 1200BPS Jumper is not shorted: 2400BPS
