RAK2461 WisNode Bridge IO Lite

The RAK2461 WisNode Bridge IO Lite is a versatile Modbus-to-LoRaWAN converter engineered to bring digital inputs (DI), relay outputs (DO), and RS-485 communication seamlessly into LoRaWAN® networks. Designed for indoor industrial and building automation, the RAK2461 allows for reliable, long-range wireless communication, providing a convenient, scalable way to monitor and control legacy equipment.

With support for up to 200 Modbus devices, auto-channel configuration, and real-time testing, the RAK2461 ensures efficient, accurate deployment for scalable IoT applications. Built on the RAK3172-T module with TCXO, the RAK2461 provides precise frequency stability, even in temperature-variable settings, and includes a watchdog timer for enhanced reliability, making it the ideal choice for critical installations.

The device comes in two variants:

• RAK2461 WisNode Bridge IO Lite – RS485-DIx4-DOx1 – One RS485 interface, four digital inputs(DI), one digital output(DO)
• RAK2461 WisNode Bridge IO Lite – RS485-DOx4 – One RS485 interface, four digital outputs(DO)

Product Features

• High Modbus Polling Capacity: Supports up to 200 Modbus devices, significantly more than typical Modbus-to-LoRaWAN converters. This makes the RAK2461 ideal for large-scale applications, reducing the need for multiple devices and simplifying network infrastructure.
• Robust Reliability with Watchdog Timer: The built-in watchdog timer provides an additional layer of reliability for continuous operation. It monitors the system for software issues or potential crashes and automatically resets the device if unresponsive, ensuring high uptime for mission-critical deployments.
• Wide Temperature Range: Operates from -20°C to +70°C, making it suitable for demanding industrial and building environments.
• Mounting Options: Supports both DIN rail and wall mounting, catering to various installation needs in control panels and automation setups.
• Wide Voltage Input: Accepts 9V ~ 24V DC power input, allowing compatibility with a range of industrial power sources

Advanced Configuration & Easy Integration with IO.Box

The RAK2461 is compatible with IO.Box, a cross-platform configuration tool that simplifies the setup and management of LoRaWAN-enabled IO devices. This tool offers:

• Real-Time Data Testing: Verify Modbus, DI, and DO sensor configurations in real time to ensure correct setup before installation.
• Auto Channel Selection: Automatically sets up LoRaWAN channels, reducing manual adjustments and ensuring optimal performance.
• LNS Integration: Single-click integration with popular LoRa Network Servers (currently supporting ChirpStack, with more platforms planned).
• Bulk Deployment Ready: Designed for scale, the IO.Box offers import/export functions, simplifying large-scale sensor setups and enabling quick, centralized configuration for mass deployments.

Applications

• Industrial Automation: HVAC systems, lighting control, and water or gas metering.
• Building Automation: Energy monitoring, sensor integration, and control of legacy equipment.
• Smart Infrastructure: Ideal for retrofit projects, allowing legacy systems to communicate wirelessly over LoRaWAN.
