Tips: Data transmission unit (DTU) application.

Data transmission unit is specially developed for Modbus RS232/RS485 application scenarios. Its unlimited package length can replace communication cables, is the best choice for Modbus wireless upgrade. Data transmission unit, as a communication medium, has a certain scope of application. It provides real-time and reliable data transmission of monitoring signals in private networks under certain special conditions. It has characteristics of low cost, convenient installation and maintenance, strong diffraction capability, flexible network structure, and wide coverage. 

DTU is suitable for many and scattered and complicated geographical environments. It can be connected to data terminals such as PLC, RTU, rain gauge, liquid level gauge, etc. It is widely used in power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries.
