RAKwireless RAK2461 | WisNode Bridge IO Lite (RS485 & Digital IO to LoRaWAN)

The RAK2461 WisNode Bridge IO Lite is a versatile industrial actuator and data bridge that enables the seamless integration of legacy hardware into modern LoRaWAN® ecosystems. Based on the robust RAK3172-T module, this device allows users to wirelessly monitor RS485 Modbus registers, track digital input states, and remotely trigger a relay output. Its compact design and industrial-grade reliability make it a perfect choice for factory floor automation, smart city infrastructure, and utility management.

Versatile Field Integration

Multi-Protocol Bridge Combines Modbus RS485 polling with digital input tracking and relay control in a single LoRaWAN node. Sensor Power Source Provides dedicated 12V/500mA and 5V/500mA outputs to eliminate the need for external sensor power supplies. High-Efficiency Radio Supports LoRaWAN 1.0.3 Class A and C with high sensitivity and transmission power up to 22dBm. Mounting Flexibility Supports versatile mounting options including DIN-rail, suitable for standardized industrial control cabinets.

Industrial Applications

• Smart Metering: Connect Modbus-based electricity or water meters to wireless infrastructure for remote billing and monitoring. • Process Automation: Monitor dry contact switch states (limit switches, door sensors) and trigger relays (pumps, alarms) remotely. • Smart Buildings: Integrate legacy HVAC or lighting controllers into unified building management systems via LoRaWAN.

Technical Integration

The RAK2461 operates across all global LoRaWAN® frequency bands (EU868, US915, AU915, etc.) and is fully compatible with standard LoRaWAN gateways. This RS485-DIx4-DOx1 variant is designed for 12-24V DC input and provides an ungrounded, normally open/closed relay interface.
