Milesight IoT UC502-N03GL Controller, NB-IoT content_copy

The Milesight UC502-N03GL is a ruggedly designed industrial-grade IoT controller with NB-IoT connectivity, conceived for decentralized control and monitoring of external devices in demanding environments. Thanks to its integrated digital and analog interfaces and energy-efficient NB-IoT technology, the device is ideally suited for applications in Smart Farming, pump control, irrigation systems, access control, and remote monitoring of industrial facilities—particularly where a LoRaWAN infrastructure is not available. The global LTE Cat NB2 connection ensures reliable, wide-area data transmission even in remote regions, making the controller especially suitable for mobile and distributed systems.

A particular advantage of the UC502-N03GL is its flexible control logic, which can be configured via the Milesight ToolBox or standard protocols such as MQTT, HTTP, and CoAP. The integrated battery function provides safe backup operation during power outages, increasing the availability of critical systems. The IP67-certified housing protects the device against dust and water, making it suitable for outdoor use, even under extreme weather conditions. The controller can be mounted on a DIN rail, wall, or pole, enabling flexible integration into existing infrastructures. Compatibility with leading cloud platforms such as Milesight IoT Cloud, Azure, and AWS allows seamless integration into existing IoT ecosystems.
