Product Descriptions
E18-DTU (Z20-485) and E18-DTU (Z27-485) are wireless radios based on ZigBee 3.0 technology, with multiple functions such as transparent transmission and protocol transmission. Wireless data transmission radio, as a communication medium, has a certain scope of application, just like fiber optic cables, microwaves, and open lines. It provides real-time and reliable data transmission of monitoring signals in private networks under certain special conditions. It has the characteristics of low cost, easy installation and maintenance, strong diffraction ability, flexible network structure, and long coverage range. It is suitable for situations with many scattered points and complex geographical environments, and can be connected to data terminals such as PLC, RTU, rain gauge, liquid level gauge, etc.
Product Features
★ All core components are imported with original packaging. Compared with similar imported data transmission radios, it has the most advanced functions, the smallest size, and the best price.
★ Multiple options for transmission power.
★ Working temperature range: -40 ℃~+85 ℃, suitable for various harsh working environments, truly industrial grade products.
★ All aluminum alloy shell, compact size, easy installation, good heat dissipation; Perfect shielding design, good electromagnetic compatibility, and strong anti-interference ability.
★ Multiple protection functions such as power reverse protection, overvoltage protection, and antenna surge protection greatly increase the reliability of the radio station.
★ Powerful software features, all parameters can be set through programming, such as power, frequency, address ID, etc.
★ Built in watchdog and precise time layout. Once an exception occurs, the module will automatically restart and continue to work according to the previous parameter settings.
