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

The Milesight UC300 is not a single-purpose sensor. It is a compact IoT controller built for distributed monitoring and control tasks. It combines several industrial interface types in one device, which makes it suitable for projects where different field signals need to be collected, processed, and forwarded. Over LoRaWAN on EU868, the controller can send data to a platform while also handling local control logic.

Typical use cases include utility rooms, panel retrofits, substations, building automation, water and environmental systems, energy and utility monitoring points, and smaller industrial installations. In these applications, the goal is often not just to transfer one measurement, but to handle several analog and digital signals at the same time. That is exactly where the UC300 fits as a central node for sensors, pulse inputs, actuators, and serial devices.

The controller provides analog inputs, digital inputs and outputs, plus RS232 and RS485. It also includes two PT100 inputs for temperature measurement. This allows pressure, level, or process signals, switching states, pulse counts, relay outputs, and Modbus devices to be combined within one field controller. For integrators, the RS485 port is especially useful because it can serve as a collection point for multiple field devices.

One key feature is local logic. With the built-in IF-THEN command system, the UC300 can execute actions autonomously even when the network is unavailable. That is useful for simple control tasks, threshold logic, timed data collection, or local reactions to input signals without depending on the cloud for every decision.

The UC300 is therefore most relevant for projects that need a robust and flexible IoT control unit with LoRaWAN connectivity. DIN rail, wall, or desktop mounting, a metal housing, serial interfaces, and multiple I/O types make it a practical hardware platform for professional monitoring and automation deployments.
