Product Description

The Milesight UC50x series represents a versatile and robust multi-interface LoRaWAN® controller, specifically engineered for demanding environments. This series is well-suited for various applications, including meter reading, environmental data acquisition, and other IoT deployments that require reliable data collection and control.

One of the standout features of the UC50x series is its array of rich industrial interfaces, which includes GPIO, AI, RS232/485, and SDI-12. This diversity in connectivity options enables the device to monitor and control multiple field sensors or devices simultaneously. The inclusion of an SDI-12 interface particularly enhances its utility in environmental data acquisition, connecting seamlessly with a wide range of instruments used in weather, hydrological, and agricultural monitoring.

The UC50x series is built to withstand harsh conditions, evidenced by its IP67 rated enclosure that offers robust protection against water ingress, corrosion, and vibrations. This makes it suitable for deployment in challenging all-weather environments. Additionally, the series provides flexible power supply options, including solar and battery power, catering to various operational needs.

Timely alerts and notifications are another significant aspect of the UC50x series. It enables data threshold reporting, triggering alerts when sensor readings exceed set thresholds. This feature facilitates proactive monitoring and ensures timely responses to potential issues.

With internal and external antenna versions available, the UC50x series provides flexibility in antenna placement to ensure optimal signal strength and range, even in environments with obstacles or challenging RF conditions. Furthermore, the device can store up to 600 sets of historical data records, securing the traceability of reported information.
