[Introduction]:E18-DTU (Z27-485) is a wireless data transmission station based on ZigBee3.0 technology, with multiple functions such as transparent transmission and protocol transmission. As a communication medium, wireless data transmission station has a certain scope of application like optical fiber, microwave, and open wire: it provides real-time and reliable data transmission of monitoring signals in private networks under certain special conditions, and has the advantages of low cost, easy installation and maintenance. Convenience, strong diffraction ability, flexible network structure, and long coverage are suitable for occasions with many scattered points and complex geographical environments. It can be connected with data terminals such as PLC, RTU, rain gauge, and liquid level gauge.
