E830-DTU (2R2-433L) Wireless Data Transmitter MODBUS RTU RS485

E830-DTU(L) Series New Generation of MODBUS RTU Spread Spectrum Technology.

E830-DTU (2R2-433L) is a data transmitter utilizing military modular LoRa technology. It offers multiple transmission modes and operates in the frequency band of 430MHz. This transmitter provides a clear RS485 interface and supports an input voltage range of 8–28 V. The spread spectrum technology with direct-sequence LoRa delivers longer communication distances while benefiting from concentrated power density and strong resistance to interference. It is equipped with FEC software and a forward correction algorithm, which boasts high coding efficiency and robust correction capabilities. In the event of sudden disturbances, it can proactively correct corrupted data files, significantly enhancing reliability and transmission distance. In the absence of FEC, such files may only be discarded. It is capable of encrypting data. The data transmitted wirelessly through the transmitter and receiver are random, making data interception futile due to complex encryption and decryption algorithms. Its length can be adjusted 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 a similar range to optical fibers, microwave, and light lines: it provides reliable transmission of monitored signal data in private networks under certain special conditions, with low cost for installation and maintenance. Its use is convenient, boasts strong diffraction capability, flexible network structure, and extensive coverage. It is suitable for applications with many nodes and dispersed, complex geographic environments, etc. It can be connected to PLC, RTU, rain gauges, liquid level meters, and other data stations.

Features:

• All core components are imported, providing advanced functions, smaller sizes, and better pricing.
• Utilizing military modulation technology LoRa with data encryption, it offers packet length settings.
• Large standalone packets, with packet size up to 240 bytes, can be adapted to Modbus.
• Simple and effective power supply design, supporting power adapter or wave ripple mode, accommodates voltage sources of 8–28 V.
• Transmission power up to 1 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 based on the current surrounding noise intensity. Communication success in challenging environments is significantly improved.
• Remote setting or reading of wireless module parameters can be accomplished through wireless command transmission. Multi-level network relay can be realized, effectively extending communication distance over very long ranges.
• With a temperature compensation circuit, frequency stability is better than ±1.5PPM.
• Operational temperature range: -40 °C to +85 °C, to adapt to the most demanding working environments.
• The casing is made of aluminum alloy, compact in size, easy to install, and offers excellent heat dissipation; perfect shielding design with good electromagnetic compatibility and strong interference resistance.
• Features multiple protective functions such as anti-reverse connection, overload protection, or antenna surge protection, significantly enhancing the reliability of the device.
• Powerful software functionalities, with all parameters programmable: e.g., power, frequency, baud rate, ID address, etc.
• Very low power consumption, standby current is only 10 mA (lower than energy consumption in sleep and power-saving modes), and transmission current is ≤0.1 A.
• Thanks to the built-in control device and precise timing, once a deviation occurs, the transmitter restarts automatically and continues operating according to previous parameter settings.
