E90-DTU(400SL44) 25W high power wireless digital radio station 40km long distance lora modem 433mhz rf transceiver rs232 rs485

Product Descriptions

E90-DTU (400SL44) is a true high-quality industrial wireless data transceiver. The transceiver uses LORA spread spectrum technology. Its strong anti-interference ability makes wireless communication more stable and reliable in industrial sites. 

It has multiple transmission modes, working in the (410.125 ～ 493.125MHz) frequency band (the default is 433.125MHz), and the radio provides a transparent RS232 / RS485 interface. LoRa Direct Sequence Spread Spectrum technology will bring 

longer communication distance and has the advantage of strong anti-interference ability. The module has software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability. In the case of sudden 

interference, it can actively correct the interfered data packets, which greatly improves reliability and transmission distance. Without FEC, such packets can only be discarded. The transceiver has a data encryption function. The data transmitted by the transceiver over the air is random. Through strict encryption and decryption algorithms, the data interception is meaningless. Packet length setting is available to support different real-time and data packets. 

As a communication medium, wireless data transceiver has the same scope as optical fiber, microwave and bright line: it provides real-time and reliable data transmission of monitoring signals in private networks under certain special conditions, with 

low cost, installation and maintenance. It is convenient, has strong diffraction ability, flexible networking structure and long coverage. It is suitable for occasions with many points and scattered, complex geographical environment, etc. It can be 

connected with PLC, RTU, rain gauge, liquid level meter and other data terminals.
