EBYTE LoRa Relay RS232 RS485 868MHz 915MHz 1W Long Range Modbus Transceiver and Receiver RSSI Wireless RF Transceiver - E90-DTU(900SL30)

• E90-DTU (900SL30) is a data transceiver with military-grade LoRa modulation technology. With multiple transmission modes, it works in the (850.125~930.125MHz) frequency band (Default 868.125MHz). The transceiver provides transparent RS232/RS485 interface and supports 8~. 28V voltage input. LoRa direct-sequence spread spectrum technology will bring longer communication distances, and has the advantages of concentrated power density and strong anti-interference ability. It features a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability. In the case of sudden interference, it can proactively correct the interfered data packets, greatly improving reliability and transmission distance. In the absence of FEC, such packets can only be discarded. It has data encryption. The data transmitted by the transceiver over the air is random, and the data interception is meaningless through strict encryption and decryption algorithms. Packet length setting is available to support different real-time and data packets. E90-DTU (900SL30) works in the ISM 868/915MHz band with a communication distance of up to 10km. 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. Warranty: We have 1 year warranty.
