Product Descriptions

E90-DTU (400SL22) is a data transceiver with military-grade LoRa modulation technology. With multiple transmission modes, itworks in the (410.125-493.125MHz) frequency band (Default 433.125MHz). The transceiver provides transparent RS232/RS485interface and supports 8~. 28V voltage input. LoRa direct-sequence spread spectrum technology will bring longer communicationdistances, and has the advantages of concentrated power density and strong anti-interference ability, It features a software FEC forwarderror correction algorithm, which has high coding efficiency and strong error correction capability. In the case of sudden interference.it can proactively correct the interfered data packets, greatly improving reliability and transmission distance. In the absence of FECsuch packets can only be discarded. It has data eneryption. The data transmited by the transceiver over the air is random, and the datainterception is meaningless through strict encryption and decryption algorithms. Packet length seting is available to support diferentreal-time and data packets.

It works in the ISM 433MHz band with a communication distance of up to 5km. As a communication medium, wireless datatransceiver has the same scope as optical fiber, microwave and bright line: it provides real-time and reliable data transmission ofmonitoring signals in private networks under certain special conditions, with low cost, installation and maintenance. It is convenienthas strong difraction ability, flexible networking structure and long coverage. It is suitable for occasions with many points andscattered, complex geographical environment, etc. It can be connected with PLC, R'U, rain gauge, liquid level meter and other data terminals.

Product Features

• All core components are imported, featuring the most advanced functions, the smallest volume and the best price.

• 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 eflicient power supply design, support power adapter or crimping mode, support 8~28V power supply.

• Transmit power is up to lW, multi-level adjustable, with all technical indicators meeting European industrial standards.

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

• Remotely configure or read wireless module parameters by sending command packets wirelessly.

• Multi-level relay networking can be realized ,which efectively extends communication distance for ultra-long-distancecommunication.

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

• Operating temperature range:-40 °~+85 oC,to adapt to a variety ofharsh working environment.

• All-aluminum alloy casing, compact size, easy installation and good heat dissipation, perfect shielding design, with good electromagnetic compatibility and strong anti-interference ability.

• Multiple protecton functons such as power reverse connecton protection, over-current protection, and antenna surge protectiongreatly increase the reliability ofthe device.

• Powerful soltware functions, all parameters can be programmed: such as power, frequency, air data rate, address lD, etc.

• Ultra-low power consumption, the standby current is only 10mA (lower than power consumption in power-saving mode and sleep mode), and the transmitting current is ≤0.1 A.

• With built-in watchdog and precise time lavout, once an exception occurs,. the transceiver will automatically restart. and continueto work according to the previous parameters.
