Description

The Milesight UC502 (NB-IoT/Cat-M1 Version) is a professional Cellular Multi-Interface Controller engineered for reliable remote monitoring where solar power is impractical. Using NB-IoT or LTE Cat-M1 connectivity, the UC502 provides a direct path to the cloud for diverse industrial sensors. Its versatile interface array—including Modbus RTU (RS485/232), SDI-12, and Analog Inputs—allows for the integration of pressure sensors, flow meters, and environmental probes. Housed in a waterproof IP68 enclosure and powered by three replaceable 9,000 mAh ER26500 Li-SOCl2 batteries (27,000 mAh in total) or an external 5–24 V DC supply via the M12 connector, it offers a "set-and-forget" solution for critical data acquisition in remote fields, basements, and utility stations.

Engineered for Remote Operational Stability

Durability The IP68 enclosure ensures protection against 1m submersion for 7 days, making it ideal for monitoring in high-humidity zones or flood-prone areas.
Edge Intelligence & Storage Features local data storage for up to 10,000 entries and automatic retransmission logic to protect data continuity during cellular signal loss.

Industrial Monitoring Scenarios

• Utility Sub-metering: Collect data from Modbus-enabled energy or water meters in remote commercial centers over NB-IoT or Cat-M1.
• Environmental Hydrology: Connect SDI-12 level probes and water quality sensors in remote riverbeds or reservoirs.
• Agriculture Tech: Monitor soil moisture and nutrients across distributed farms without the need for on-site power infrastructure.
