Product Descriptions
E90-DTU(433C30E) V2.0 supports adaptive network rate (up to 100 full-duplex), provides six working modes of TCP Server, Tcp Client, UDP Server, UDp Client, HTTp Client, and MOTT Client. Mode supports six-way client connection:
It supports a variety of Modbus gateways, which can perform simple interconversion between Modbus TCp data and Modbus R'TU data. record and send the read commands, and actively upload to the server through pre-stored commands:
Different from traditional digital radios, E90-DTU(433C30E)_V2.0 is specially developed for Modbus application scenarios. The feature of unlimited package length can replace communication cables and is a worry-free choice for Modbus wireless upgrades. The radio works in the 433vHz frequency band, and the communication distance can reach 3km;
