E32-DTU LoRa Wireless Data Transmitter

E32-DTU LoRa Wireless Data Transmitter

The E32-DTU series are wireless data transmitters operating at frequencies of 433M/868M/915MHz with standard RS232/RS485 connectors. These are half-duplex TX and RX modems utilizing LoRa technology and a transparent transmission mode. The voltage supply range is between 8V and 28V.

The direct sequence spread spectrum technology of LoRa allows for longer communication distances and better power density concentration, as well as exceptional resistance to interference. The FEC algorithm enables higher coding efficiency and correction capability. Upon sudden interference, corrupted data is proactively corrected, significantly enhancing reliability and communication distance. Without FEC, corrupted data may be lost. The transmitter includes data encoding and compression features. Data transmitted wirelessly shows randomness, and a rigorous algorithm can prevent data interference. Thanks to the data compression feature, transmission time can be reduced, which also means lower probability of data interference, enhancing reliability and communication efficiency.

Communication media similar to optical fibers, microwave transmission, or cables, the wireless data transmitter can be used in various ways: it provides reliable transmission of specific network monitoring signals under specific conditions in real-time, at low cost, with easy installation and maintenance, excellent diffraction capability, and can be connected to PLC, RTU, rain gauges, level sensors, etc.

Features:

• All core components are imported, our transmission modems offer more advanced features, smaller sizes, and better prices.
• TX power range is between 0.5 to 5 W, all technical parameters comply with European industrial standards.
• With a temperature compensation circuit, frequency stability is better than ±1.5PPM.
• Operating temperature range: -40 °C to +85 °C, adaptable to various demanding working environments. This product is primarily designed for industrial environments.
• The casing is made from aluminum alloy, with a compact size, good heat dissipation, and excellent shielding with outstanding electromagnetic compatibility and strong interference resistance.
• Protection against backflow, overload, and antenna overvoltage significantly enhances product reliability.
• All parameters can be programmed: for example, TX power, frequency, baud rate, ID address, etc.
• Very low power consumption, standby current is only 50 mA (energy consumption in power-saving mode and sleep mode is lower), TX current is ≤01.2 A (less than 5 W).
• With a built-in control device and precise timing, once a deviation occurs, the transmitter automatically restarts and continues working according to the previous parameter settings.
• The transmitters use original SEMTECH SX1276/SX1278 chips, with users highly appreciating the exceptional reliability of these products.
