Product Descriptions

E90-DTU (900SL33) is a wireless digital transmission station using military LoRa modulation technology, with a variety of transmission modes, working in 850.125~930.125MHz) frequency band (default 868.125MHz). The station provides transparent RS232 / RS485 interface and supports 8~28V voltage input. LoRa direct sequence expansion technology will bring further communication distance, and has the advantages of concentrated power density and strong anti-interference ability. The module has the software FEC forward error correction algorithm, which has high coding efficiency and strong error correction ability. In the case of sudden interference, it can actively correct the disturbed data packets, greatly improving the reliability and transmission distance. In the absence of FEC, such packets can only be discarded. The radio station has the function of data encryption, and the data transmitted by the radio station is random, which makes the data interception meaningless through strict encryption and decryption algorithm; supports the subcontracting length setting and supports different real-time and data packets. 

Wireless digital radio as a kind of communication media, and optical fiber, microwave, open line, have certain scope of application: it provides some special conditions of private network monitoring signal of real-time and reliable data transmission, with low cost, convenient installation and maintenance, shooting ability, flexible network structure, far coverage characteristics, suitable for point and scattered, complex geographical environment, and PLC, RTU, rainfall gauge, liquid level meter data terminal connection.

Product Features

★ Using the latest Lo R a technology, than the traditional Lo R a digital radio distance is farther, more powerful performance;

★ Support AT instruction, more convenient to use;

★ Support serial port upgrade firmware, update firmware is more convenient;

★ Under ideal conditions, the communication distance can reach 16km;

★ Support for the global license-free ISM 868 / 915 MHz frequency band;

★ Support data encryption, the subcontract length can be set;

★ Super large single package, single package support up to 240 bytes, suitable for Modbus protocol;

★ Simple efficient power supply design, support power supply device or voltage mode, support 8~28V power supply;

★ Launch power up to 2W, and support multi-stage adjustable, all technical indicators meet the European industrial standards;

★ Support LBT function, the station automatically sends according to the current ambient noise intensity. Greatly improve the communication success rate of the module in the harsh environment;

★ Support wireless sending command packet, remote configuration or reading wireless module parameters;

★ Support the communication key function, and effectively prevent the data from being intercepted;

★ It can realize the multi-stage relay networking, effectively expand the communication distance, and realize the ultra-long distance communication;

★ Using the temperature compensation circuit, the frequency stability is better than ± 1.5 PPM;

★ Working temperature range: -40℃ ~ + 85℃, adapt to a variety of harsh working environment, real industrial-grade products;

★ Aluminum alloy shell, compact volume, convenient installation, good heat dissipation; perfect shielding design, good electromagnetic compatibility, strong anti-interference ability;

★ Power reverse connection protection, adoptive protection, antenna surge protection and other multiple protection functions, greatly increase the reliability of the station;

★ Powerful software functions, all parameters can be programmed by setting: such as power, frequency, air rate, address ID, etc.;

★ Ultra-low power consumption, waiting current is only 15 mA (power saving mode and sleep mode power consumption is lower);

★ Built-in watchdog, and precise time layout, in the event of abnormalities, the module will automatically restart, and can continue to work according to the previous parameter settings.
