Bezdotykový datový vysílač E800-DTU(433L20-485) s technologií LoRa

Series E800-DTU(L) Next Generation of LoRa Spread Spectrum Technologies.

E800-DTU(433L20-485) is a wireless data transmitter utilizing military modular LoRa technology. It offers multiple transmission modes and operates on frequency bands 410 ~ 441MHz. This transmitter provides a clear RS485 interface and supports an input voltage of 8–28 V. The spread spectrum technology with direct sequence LoRa enables longer communication distances and has the advantages of concentrated power density and strong interference resistance. It is equipped with FEC software featuring a forward correction algorithm with high coding efficiency and robust correction capabilities. In case of sudden disruption, it can proactively correct 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. Air-transmitted data via the transmitter with receiver is random, and data capturing is impractical due to complex encryption and decryption algorithms. Their length can be configured to support various real-time and data packets.

Operates in the ISM 433MHz band with a communication range of up to 5 km. As a communication medium, the wireless data transmitter with receiver has the same range as optical fibers, microwave, and light lines: providing reliable transmission of monitored signal data in private networks under certain specific conditions, with low costs, installation, and maintenance. Its use is convenient, it has a 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, boasting advanced features, smaller dimensions, and better pricing.
• Utilizing military modulation technology LoRa with data encryption allows for configurable packet length.
• Large standalone packets, one packet up to 240 bytes in size, can adapt to Modbus.
• Simple and efficient power supply design, supports power adapter or ripple mode, accommodating voltage sources of 8–28 V.
• Transmission power up to 1 W, adjustable to multiple levels with all technology indicators meeting European industrial standards.
• Supports LBT functions; the transmitter with receiver automatically waits to send data based on the current noise intensity. Communication module success in challenging environments is significantly improved.
• Parameters of the wireless module can be remotely set or read via wireless command transmission. Multi-level network relay implementation effectively extends communication distance for long-range communications.
• With a temperature compensation circuit, frequency stability is better than ±1.5PPM.
• Operating temperature range: -40 °C to +85 °C, to adapt to the most demanding working environments.
• The housing is made of aluminum alloy, compact, easy to install, and dissipates heat well; perfect shielding design with good electromagnetic compatibility and strong interference resistance.
• Has multiple protective features such as reverse polarity protection, overload protection, or surge protection for antennas, significantly increasing device reliability.
• Powerful software features; all parameters can be programmed: e.g., power, frequency, transmission rate, ID address, etc.
• Very low power consumption, backup current is only 10 mA (lower than power consumption in power-saving and sleep modes), and transmission current is ≤0.1 A.
• With an integrated control device and precise timing layout, once a deviation occurs, the transmitter automatically restarts and continues operations based on previous parameter settings.
