Milesight LoRaWAN IoT Multi I/O Controller UC300-868M

The Milesight UC300-868M is a versatile multi-interface IoT controller designed for connecting, monitoring, and managing a wide variety of wired sensors and devices over LoRaWAN®. With its comprehensive I/O support—4 digital inputs, 2 relay outputs, RS232, RS485, analog current and voltage inputs, and PT100 RTD temperature sensors—the UC300 is perfect for complex control scenarios in smart buildings and industrial automation.

It supports transparent Modbus RTU communication, pulse counting, and relay switching. Thanks to built-in IF‑THEN logic, data storage, threshold alarms, and Milesight D2D communication, the UC300 can operate independently even when the LoRaWAN® network is temporarily unavailable.

The device is built for robust industrial environments, featuring a metal enclosure, wide temperature tolerance (-20°C to 60°C), and flexible mounting options: desktop, wall, or DIN rail. It can be powered via 5–24V DC terminal block or USB Type‑C, and is configured easily through USB or downlink commands.

With Milesight IoT Cloud integration and support for advanced edge logic, the UC300 allows for rapid deployment of smart infrastructure with minimal maintenance overhead.

Key Applications:

• Smart manufacturing and industrial process control

• HVAC and facility automation

• Environmental and energy monitoring

• Remote sensor integration using RS485

• Temperature sensing with PT100

• IoT relay and alarm actuation
