E90-DTU SL Series LoRa Data Transmission Station

E90-DTU SL Series: The New Generation of LoRa Spread Spectrum Technology.

The E90-DTU SL series is a data transmitter featuring military-grade modular LoRa technology. It offers multiple transmission modes and operates in frequency bands of 220-236MHz, 410-493MHz, and 850-930MHz. The transmitter provides an RS232/RS485 interface and supports an input voltage of 8–28 V. The spread spectrum technology with direct sequence LoRa ensures long communication distances and high resistance to interference. With FEC software using a forward correction algorithm, it achieves high encoding efficiency and strong correction capabilities, enhancing reliability and transmission distance. In case of signal interference, the data file correction occurs automatically, ensuring stable and secure transmission. Data transmitted over the air is encrypted, making eavesdropping very difficult. The length of the transmitted data packets can be adjusted to cater to specific real-time applications and different data formats.

It operates in the ISM bands of 220-236MHz, 410-493MHz, and 850-930MHz with a communication distance of up to 40 km. The transmitter is ideal for applications in private networks that require reliable data transmission under challenging geographical conditions. It is suitable for a wide range of devices, including PLCs, RTUs, rain gauges, and liquid level meters.
