- Overview：
- NB-IOT：LTE Cat NB2: B3/B5/B8
- Provide 2 channels of analog input (resolution 12bit), support 4-20mA current and 0-5V voltage
- Support TCP / UDP, multiple socket protocols and multi server parallel communication
- Comway Protocol
- Standard TCP/UDP Protocol
- It provides a controllable power output. 24V / 12V can be selected by jumper, or the output is equal to the input voltage, which is convenient to control the sensor power supply in micro power consumption mode
- 485 port 1 is the Modbus master port and supports querying the 485 slave devices connected to it through Modbus RTU protocol
- Automatic online network timing, with clock error of second level
- Run in micro power consumption mode, sleep standby power consumption is 50ua@7.2v
- Upload message: in string format, it can be connected to dc-web cloud monitoring to display data on computer or mobile terminal
