E90-DTU(400SL37) lora sx1268 module 433mhz data transceiver military-grade lora device wireless transmitter and receiver

Product Descriptions

E90-DTU(400SL37)is a data transceiver with military-grade LoRa modulation technology.With multipletransmission modes, it works in the (410.125~493.125MHz) frequency band (default 433.125MHz).The transceiveiprovides transparent RS232/R$485 interface and supports10~36V voltage input. LoRa direct-sequence spread spectrumtechnology will bring longer communication distances, and has the advantages of concentrated power density and stronganti-interference ability. It features a software FEC forward error correction algorithm, which has high coding efficiencvand strong error correction capability. in the case of sudden interference. it can proactively correct the interfered datapackets, greatly improving reliability and transmission distance. In the absence of FEC, such packets can only bediscarded. It has data encryption. The data transmited by the transceiver over the air is random, and the data interceptionis meaningless through strict encryption and decryption algorithms. Packet length setting is available to support differentreal-time and data packets.

As a communication medium, wireless data transceiver has the same scope as optical fiber, microwave and brightline. it provides real-time and reliable data transmission of monitoring signals in private networks under certain speciaconditions, with low cost, installation and maintenance. It is convenient, has strong difraction ability, flexiblenetworking structure and long coverage. It is suitable for occasions with many points and scattered, complexgeographical environment, etc. It can be connected with PLC, RTU, rain gauge, liquid level meter and other dataterminals.

Product Features

• Using the latest LoRa technology, it is farther away from traditional LoRa digital radio stations and has more powerful performance.

• Using military-grade LoRa modulation technology, with data encryption, the packet length is available for configuration.

• Large single package, single package is up to 240 bytes, adapt to Modbus.

• Simple and efficient power supply design, support power adapter or crimping mode, support 10 ~ 36V power supply.

• The transmission power can be up to 5W.

• Support LBT function, the transceiver automatically waits to send data according to the current ambient noiseintensity. The communication success rate of the module in harsh environments is greatly improved.

• Support wireless send command packets, remotely configure or read wireless module parameters.

• Support communication key function to effectively prevent data from being intercepted.

• Multi-level relay networking can be realized, which effectively extends communication distance forultra-long-distance communication.

• With temperature compensation circuit, the frequency stability is better than +1.5PPM

• Operating temperature range: -40°C ~+85 ° C, to adapt to a variety of harsh working environment.
