[Introduction]：E95-DTU (400F20-485) is a cost-effective wireless data transmission radio station with multiple transmission methods. It works in the (410～510MHz) frequency band (default 433MHz). The radio provides a transparent RS485 interface, adopts a plastic shell, and ismounted on a guide rail. Structure, support 8 ～ 28V voltage input. LoRa spread spectrum technology will bring a longer communication distance and has the advantage of strong anti-interference ability.
