• Simple and efficient power supply design, supports power supply or crimping mode, supports 8-28V power supply. Transmit power up to 1W, multi-level adjustable, and all technical indicators meet European industry standards
• Supports LBT function, the transceiver will automatically wait for data to be sent according to the current ambient noise level. The module's communication success rate under difficult conditions improved significantly
• Remotely configure or read wireless module parameters by sending command packets wirelessly
• Multi-level relay networks can be realized, which effectively increases the communication distance over very long distances
• Communication with the temperature compensation circuit, frequency stability is better than SPPM.
• Operating temperature range: -40 ° C- + 85 C to adapt to various harsh working conditions
• All aluminum alloy housing, compact size, easy installation and good heat dissipation; excellent shielding design, with good electromagnetic compatibility and strong anti-interference ability.
• Multiple protection functions, such as reverse power supply protection, overcurrent protection and antenna overvoltage protection, greatly enhance the reliability of the device.
• Powerful software functions, all parameters can be programmed: such as power, frequency, data rate, address ID, etc.
• Very low power consumption, the standby current is only 10mA (lower than the power consumption in energy saving mode and sleep mode), and the transmit current is 0.1A
• Thanks to the built-in watchdog and precise timing system, after an exception occurs, the transceiver will automatically restart and continue to work according to the previous parameters.

Description

The E90-DTU (900SL30) is a transceiver with military-grade LoRa modulation technology. Thanks to many transmission modes, it operates in the frequency band (850.125-930.125 MHz) (by default 868.125 MHz). The transceiver provides a transparent RS232 / RS485 interface and supports 8-28V Voltage Input. LoRa direct sequence spread spectrum technology will bring greater communication distances, and has the advantages of concentrated power density and strong anti-interference capability. It has a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability. In case of sudden disruptions, it can proactively correct disrupted data packets, greatly improving the reliability and transmission distance. In the absence of an FEC, such packets can only be rejected. Has data encryption. Data sent by the transceiver wirelessly is random and data interception is meaningless thanks to stringent encryption and decryption algorithms. It is possible to set the packet length to support different data and real time packets.

Works in the ISM 868 / 915MHz band with communication range up to 10km. As a communication medium, the wireless data transceiver has the same range as optical fiber, microwave and clear line: it ensures reliable real-time data transmission of monitoring signals in private networks under certain special conditions, with low cost, installation and maintenance. It is convenient, has strong diffraction ability, flexible lattice structure and long range. It is suitable for situations with multiple points and scattered complex geographic environment etc. It can be connected with PLC, RTU, rain gauge, liquid level gauge and other data terminals.
