Data transfer unit is abbreviated as DTU, is a wireless data acquisition device specially used to convert serial port data to IP data or convert IP data to serial port data. It is transmitted through a wireless communication network. Data transfer unit uses advanced ultra-narrowband modulation technology, which greatly improves communication distance and transmission stability. ATO has a variety of DTU models for selection, adapts to Modbus protocol, supports RS485 and RS232 communication interfaces, max transmission distance can be up to 20km. Some specific models use LoRa modulation technology, making DTU has strong diffraction and penetration, meeting a variety of data transmission needs.
Data transfer unit (DTU) is a remote data control product. Wireless acquisition function supports Modbus RTU protocol, communication interface is RS-485, transmission distance is 8km. DTU has switch value follow and control acquisition functions. It supports 2-channel isolation switch inputs and 2-channel relay outputs.
Data transmission unit adopts ultra-narrowband modulation technology. Built-in power amplifier (PA) and low-noise amplifier (LNA), make the maximum transmit power reach 5W. Transmission distance can be up to 10km, communication interface is RS232/RS485, be adapted to Modbus protocol. Support high-speed continuous uninterrupted data transmission.
Data transfer unit uses military-grade LoRa modulation technology, spread spectrum, and strong diffraction. Transmission distance can be up to 20km, transmission power can select 1W or 5W. The digital transceiver provides transparent RS232/RS485 interface, working frequency band is 433MHz. It can be connected with PLC, RTU, level gauge and other data terminals.
Data transfer unit is data transceiver using advanced ultra-narrowband modulation technology.
