RAK2461 WisNode Bridge IO Lite Datasheet

Overview

Description

The RAK2461 WisNode Bridge IO Lite bridges different Digital Inputs, Outputs (Relay), and RS-485 communication to LoRaWAN® for industrial applications. The device relays data using the LoRaWAN network as a means of wirelessly transmitting to and from the end devices.

It is an ideal solution for seamless LoRaWAN communication within industrial environments. Engineered with industrial-grade reliability and based on the RAK3172-T LoRaWAN module, the RAK2461 ensures long-range connectivity, even in extreme temperatures from -20° C to +70° C.

This device can operate on all LoRaWAN bands within the standard regional parameters defined by the LoRa Alliance®. It supports wall and DIN rail mounting for flexible deployment in industrial automation and smart infrastructure applications. The RAK2461 can be configured through IO.Box for LoRaWAN, RS485, DI/DO, and system settings. Together with a RAK Gateway , it enables a simple way to build a new wireless industrial system or extend an existing deployment.

Power Interfaces

RAK2461 WisNode Bridge IO can be powered by a DC power supply (9 V ~ 24 V) through the Vin, the voltage must be stable. This power supply is also used to power sensors or devices connected to Vout.

Interfaces	Description
Vin	Stable voltage input: 9 V ~ 24 V
GND	Ground, Vin and GND form a voltage input loop
Vout	Voltage output: 9 V ~ 24 V (depending on the input) Vout output is controlled by MCU
GND	Ground, Vout and GND form a voltage output loop

Console

The USB type-C port of the device is used for configuration. For configuration purposes, the device can also be powered by the Console port. But type-C port will not provide power to sensors or devices connected to the Vout (J4/pin3).

Reset

Press the Reset button to restart the device.

LED Indicators

LEDs	Status Indication Description
PWR	Static on - System works. PWR is controlled by MCU.
Data	Flicker - Data is being transferred Off - No data transmission

LoRa

LoRa antenna interface. RP-SMA external omnidirectional antenna.

Data Interfaces

RS-485 interface: RS-485 master baud rate is 9600. Multiple devices can be connected, but for more than 5 devices the recommended length is 30 m.
Relay (DO): The maximum voltage is 240 V. You can choose between NC and NO based on the use case. (DC - 30 V / 3 A, AC - 250 V / 3 A).
Photocoupler (DI): By default, DI supports Dry Contact. If Wet Contact is required, you can contact RAK technical support. The maximum input voltage should be 5 V and the DI COM should be connected to the negative pole.
