E90-DTU (400SL22P) Industrial Lora Data Transmitter

E90-DTU(SL) Series Next Generation of LoRa Spread Spectrum Technology.

E90-DTU (400SL22P) is an industrial data transmitter utilizing military modular LoRa technology. It offers multiple transmission modes and operates on frequency bands (410.125 - 493.125 MHz) (default 433.125 MHz). This transmitter provides a clear RS232/RS485 interface and supports an input voltage of 8–28 V. The LoRa direct sequence spread spectrum technology enables longer communication distances and boasts concentrated power density and strong resistance to interference. It is equipped with FEC software that uses forward error correction, providing high encoding efficiency and robust correction capabilities. In the case of sudden disruptions, it can proactively fix files with corrupted data, significantly enhancing reliability and transmission distance. In the absence of FEC, such files may simply be discarded. It has the capability to encrypt data. Data transmitted wirelessly via the transmitter to the receiver is random, and capturing data serves no purpose due to complex encryption and decryption algorithms. The length of packets can be adjusted to support various real-time data packets.

Operating in the ISM 433 MHz band, it boasts a communication distance of up to 5 km. As a communication medium, this wireless data transmitter with receiver has the same reach as optical fibers, microwave, and light lines: it provides reliable transmission of monitored signal data in private networks under certain special conditions, with low costs for installation and maintenance. Its use is convenient, with strong diffraction capability, flexible network structure, and extensive coverage. It is suitable for cases with numerous points and dispersed, complex geographic environments, etc. It can be connected with PLC, RTU, rain gauges, liquid level meters, and other data stations.

Features:

• All core components are imported, with advanced features, smaller dimensions, and better prices.
• Using military modular LoRa technology with data encryption, adjustable packet length is available.
• Large independent packets, one packet up to 240 bytes, can be adapted to Modbus.
• Simple and efficient power source design, supports power adapters or ripple mode, accommodating voltage sources from 8–28 V.
• Transmitting power up to 0.16 W, adjustable to multiple levels with all technical indicators meeting European industrial standards.
• Supports LBT functions, the transmitter with receiver automatically waits to send data considering the current ambient noise intensity. The communication success rate of the module in harsh environments is significantly improved.
• Wireless module parameters can be remotely configured or read through wireless command transmission. Multi-level network relay can be realized, effectively extending communication distance for very long-distance communications.
• With a temperature compensation circuit, frequency stability is better than ±1.5 PPM.
• Operational temperature range: -40 °C to +85 °C, adapts to the most demanding work environments.
• The casing is made of aluminum alloy, compact in size, easy to install, and has good heat dissipation; perfect shielding design with good electromagnetic compatibility and strong ability to counteract interference.
• It includes several protective features such as reverse connection protection, overload protection, or antenna surge protection, greatly enhancing device reliability.
• Powerful software capabilities, all parameters can be programmed: such as power, frequency, transmission rate, ID address, etc.
• Very low power consumption, standby current is only 10 mA (lower than power consumption in sleep mode), while transmission current is ≤0.1 A.
• With a built-in control device and precise timing, once deviation occurs, the transmitter automatically restarts and continues operation according to previous parameter settings.
