Product Descriptions

E90-DTU (400SL22P) is a true high-quality industrial-grade wireless digital radio. The power supply supports3-level protection, RS485 and RS232 support 4-level protection, and the RF port supports 4-level ESD protection. It canbe used in industrial applications where the electromagnetic environment is more complicated. The radio adopts LORA spread spectrum technology, and its powerful anti-interference ability makes wireless communication more stable andreliable in the industrial field.

It has multiple transmission modes, working in the (410.125 ~ 493.125MHz) frequency band (default 433.125MHz)the radio provides transparent RS232/R$485 interface, supports 8 ~ 28V voltage input. LoRa direct-sequence spreadspectrum technology will bring longer communication distances, and has the advantages of concentrated power densityand strong anti-interference ability. The module has a software FEC forward error correction algorithm. which has highcoding efliciency and strong error correction capability. In the case of sudden interference, it can actively correct theinterfered data packets, greatly improving reliability and transmission distance. In the absence of FEC, such packets canonly be discarded. The radio has data encryption function, and the data transmitted by the radio in the air has randomnessThe data interception is meaningless through strict encryption and decryption algorithms, the packet length setting issupported, and different real-time and data packets are supported.

As a communication medium, wireless digital radio 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 speciaconditions, with low cost and installation and maintenance.Convenient, strong diffraction ability, flexible networkstructure and long coverage. It is suitable for multi-point and location dispersion, complex geographical environment, etcIt can be connected with PLC, RTU, rain gauge, liquid level meter and other data terminals.
