Description

The RAK7431 WisNode Bridge Serial is a professional RS485 to LoRaWAN converter engineered to bring wireless connectivity to industrial field devices. By seamlessly relaying Modbus RTU data over LoRaWAN, it enables the remote monitoring and real-time control of multiple RS485 nodes across distances exceeding 15km in open environments. Its industrial-grade metal housing and wide voltage support make it an ideal choice for complex factory floors, large-scale warehouses, and smart city infrastructure.

Industrial Grade Serial Bridging

Polling & Transparent Modes Supports both a polling mode for scheduled data acquisition and a transparent mode for bi-directional serial communication, ensuring compatibility with varied industrial protocols.
Robust Field Deployment Equipped with a hardware watchdog for system stability and a micro-USB port for simplified local configuration, all housed in a durable IP31 metal casing.

Industrial Control Scenarios
