LoRa RS485 433MHz Industrial Modem Wireless Data Transmission Station DTU E95-DTU(433L20-485) Ebyte 30dBm 8km

Description

• E95-DTU (433L20-485) is a wireless data transmission DTU that uses military-grade LoRa modulation technology. It has a variety of transmission methods. It works at (410/441M) frequency band (default 433MHz). The DTU provides a transparent RS485 interface, plastic shell. rail type installation structure, support 8~28V voltage input.
• The DTU provides a transparent RS232/RS485 interface, plastic shell. rail type installation structure, support 8~28V(DC)/85~265V(AC) voltage input.
• LoRa spread spectrum technology will bring a longer communication distance and has the advantage of strong anti-interference ability.
• Low cost, convenient installation and maintenance, strong diffraction ability, flexible network structure, and long coverage.
• Suitable for many and scattered locations, complex geographical environment and other occasions, can be connected with PLC, RTU, rain gauge, level gauge and other data terminals.
