RAK Wireless WisNode Bridge RAK7431

RAK7431-03 EU868

overview

WisNode Bridge Serial (RAK7431) is a Modbus RS485 to LoRaWAN® bridge designed for industrial applications. The device wirelessly transmits Modbus data to and from end devices over the LoRaWAN network.

The WisNode Bridge Serial can operate in all LoRaWAN bands within the standard parameters defined by the LoRa® Alliance. The range in open environment is 15+km and in industrial environments where there are strong obstacles in the path of the RF signal, the performance is improved compared to conventional wireless systems due to the characteristics of LoRa as a modulation method. This allows for consistently good signal quality within the confines of large factories, densely populated offices, warehouses, etc.

This RS485 compatible device can address up to 16 client terminal nodes. Conversion to and from LoRa frames is seamless and enables control and monitoring of multiple RS485 devices in real time. Bus data for accessing and controlling the RS485 terminal nodes.

WisNode Bridge Serial can easily and quickly build a wireless industrial field control system together with RAK's LPWAN gateway and LoRa server products. WisNode Bridge Serial has an industrial protection design, supports wide-range power supply, supports wall mounting and DIN rail installation, making it easy to install and deploy on site.
