Product Descriptions

E95-DT'U (400SL22-485) is a wireless data transmission DT'U that uses military-grade LoRa modulation technology. It has avariety of transmission methods. It works in the (410.125MHz~493.125MHz) frequency band (default 433.125MHz). The DTUprovides a transparent RS485 interface, plastic shel, rail type installation structure, support 8-28V voltage input. LoRa spreadspectrum technology will bring a longer communication distance, and has the advantage of strong anti-interference ability.

As a communication medium, wireless data transmission station has a certain scope of application like optical fiber, microwaveand open wire: it provides real-time and reliable data transmission of monitoring signals in private networks under certain specialconditions.with low cost.installation andconvenience, strong difiaction ability, flexible network structure, and longnamtenancecoverage. It is suitable for many and scattered locations and complex geographic environments. It can be connected with PLC, RTUrain gauge, level gauge and other data terminals.

Product Features

? Using the latest LoRa technology, it is farther and more powerfiul than traditional LoRa digital DTU;

? Adopt mil itary-grade LoRa modul ation technology, with data encryption, and the packet length can be set;

? Adopt flame-retardant plastic shell, guide rail type installation structure, convenient and eflicient installation;

? Hidden butons are used to switch working modes to avoid false triggers, and the equipment is more reliable in operation;

? Simple high-efficiency power supply design, support power supply confi guration or line pressure mode, support 8 ~ 28V power supply,

? The transmit power can reach up to 22dBm, and supports multi-level adjustment, and all technical indicators meet European industrial standards,

? Support LB'T function, the DTU automatically waits for transmission according to the current environmental noise intensity. Greatly improve the communication success rate of the DTU in harsh environments.

? Support wireless sending of command data packets, remote configuration or reading of DTU parameters;

? Support communication key finction, effectively prevent data from being intercepted;

? It can realize multi-level relay networking, elfectively expand the communication distance, and realize ultra-long-distance communication;

? Using temperature compensation circuit, the frequency stabil ity is better than +1 5PPM;

? Working temperature range: -400~+85'℃, adapt to various harsh working environments, real industrial grade products.

? All aluminum alloy shell. compact size, convenient installation, good heat dissipation; perfect shielding design, goodelectromagnetic compatibility, strong anti-interference  ability;

? Multiple protection functions such as power reverse connection protection, over-connection protection, antenna surge protection.ete.. greatly increase the reliability ofthe DTU;

? Powerlul soltware fiunction, all parameters can be set by programming, such as power, frequency, air rate, address lD, etc.

? Ultra-low power consumption, standby current is only 1 5mA (lower power consumption in power-saving mode and sleep mode);

? Built-in watchdog and precise time layout. Once an abnormality occurs, the DTU will automatically restart and continue to workaccording to the previous parameter settings.
