E95-DTU(900SL22-485) E95-DTU module industrial grade wireless data transmission station with multi-level relay network function

Product Descriptions

E95-DTU (900SLxx-485) is a wireless data transmission radio using military-grade LoRa modulation technology. It has a variety of transmission methods and works in the (850.125MHz ~ 930.125MHz) frequency band (default 868.125MHz). The radio 

provides transparent RS485/RS232 interface , Using plastic shell, rail type installation structure, support 8 ~ 28V (DC) voltage input. LoRa spread spectrum technology will bring longer communication distance and has the advantage of strong anti-

interference ability. 

As a communication medium, wireless digital radio has a certain scope of application like optical fiber, microwave and open wire: 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 has the characteristics of convenience, strong diffraction ability, flexible network structure, and long coverage. It is suitable for occasions such as many and scattered points and complex 

geographical environment. It can be connected with PLC, RTU, rain gauge, liquid level gauge and other data terminals.

Product Features

 Using the latest LoRa technology, the distance is farther and the performance is more powerful than the traditional LoRa digital radio;

 With data encryption, sub-packet length can be set;

 Adopt flame retardant plastic shell, guide rail type installation structure, convenient and efficient installation；

 Use hidden buttons to switch the working mode to avoid false triggering, and the operation of the equipment is more reliable；

 Simple and high-efficiency power supply design, support power adapter or pressure line method, support 8 ~ 28V (DC) power supply；

 The transmit power can reach up to 22/30dBm, and supports multi-level adjustment, all technical indicators meet industrial standards；

 Support Modbus protocol transmission；

 Support LBT function, the radio automatically waits for transmission according to the current environmental noise intensity. Greatly improve the communication success rate of the radio in harsh environments；

 Support wireless sending of command data packets, remote configuration or reading of radio station parameters；

 Support communication key function, effectively prevent data from being intercepted；

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

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

 Working temperature range: -40℃ ～ +85℃, suitable for all kinds of harsh working environment, real industrial grade products；

 Multiple protection functions such as power reverse connection protection, over-connection protection, antenna surge protection, etc., greatly increase the reliability of the radio；

 The communication port and power interface adopt high isolation and high protection；

 Powerful software functions, all parameters can be set by programming: such as power, frequency, air rate, address ID, etc.；

 Built-in watchdog with precise time layout, once an abnormality occurs, the radio will automatically restart, and can continue to work according to the previous parameter settings.
