Milesight UC501 LoRaWAN Multi-Interface Controller - Internal Antenna (EU868)

The Milesight UC501 LoRaWAN Multi-Interface Controller – Internal Antenna Version is an advanced industrial IoT controller designed to connect conventional wired sensors, measuring instruments and field equipment to wireless LoRaWAN networks.

Featuring a compact, weather-resistant enclosure and a built-in LoRaWAN antenna, the UC501 provides a flexible solution for remote data acquisition, environmental monitoring, industrial automation and smart agriculture applications.

Unlike the external antenna version, this model features an integrated antenna, eliminating the need for an external LoRaWAN antenna or antenna cable and simplifying installation in outdoor and remote environments.

The UC501 combines multiple industrial interfaces in a single device, allowing different types of sensors and instruments to communicate through a common LoRaWAN connection.

It provides 2 configurable GPIO channels, supporting digital input, digital output and pulse counting functions for monitoring switches, alarms, contact states and compatible pulse-output meters.

The controller also features 2 configurable analog input channels, supporting 4–20mA current signals or 0–10V voltage signals, making it suitable for connecting industrial pressure, level, temperature and other analog transmitters.

For digital industrial instrumentation, the UC501 supports RS232 or RS485 serial communication, selectable by configuration, including Modbus RTU over RS485 for communication with compatible sensors and field devices.

The controller additionally supports SDI-12 communication, a widely used interface in environmental and agricultural monitoring equipment, including meteorological instruments, water monitoring sensors and soil measurement devices.

This combination of GPIO, analog inputs, RS232/RS485 and SDI-12 makes the UC501 particularly useful when several wired instruments need to be integrated into a single remote monitoring system.

The device also provides configurable sensor power outputs, including 3.3V and selectable 5V/9V/12V DC, allowing suitable external sensors to be powered directly from the controller within the manufacturer's specified current and operating limits.

One of the UC501's main advantages is its flexible power architecture.

The controller supports two rechargeable batteries, solar charging through a compatible solar panel, and an external 5–24V DC power supply, making it suitable for installations where continuous mains electricity is unavailable.

Depending on the selected hardware version and accessories, the UC501 can operate as part of a solar-powered remote monitoring station, providing energy for periodic measurements and wireless data transmission.

Battery capacity, solar-panel rating and supported sensor output currents can vary between hardware revisions. These parameters should be checked against the specific ordering SKU and supplied hardware.

The UC501 communicates through LoRaWAN EU868, supporting long-range, low-power wireless transmission to compatible LoRaWAN gateways and network servers.

Unlike the UC502, which supports LoRaWAN Class A operation, the UC501 supports both LoRaWAN Class A and Class C operating modes, providing additional flexibility for monitoring and remote control applications.

The controller supports OTAA and ABP network activation and can be integrated into compatible LoRaWAN infrastructures and IoT management platforms.

It also supports multicast communication, allowing supported control commands to be distributed to multiple compatible devices.

For reliable remote monitoring, the UC501 includes threshold-based alarms, change alarms, local data storage and retransmission of historical records, helping reduce the risk of data loss during temporary communication interruptions.

Configuration is available through NFC using the Milesight ToolBox mobile application and through the supported local configuration interface.

The controller is designed for installation in demanding field environments, featuring a sealed enclosure and industrial M12 connectors.

The latest manufacturer documentation lists an IP68 enclosure, while some older product documents specify IP67. The exact protection rating should be verified against the supplied hardware revision.

Its compact dimensions of 116 × 116 × 45.5 mm and support for wall or pole mounting make it suitable for field cabinets, agricultural installations, water infrastructure and remote monitoring stations.

The Milesight UC501 is an excellent solution for smart agriculture, environmental monitoring, industrial equipment monitoring, water management, remote Modbus data acquisition and solar-powered IoT applications.

By combining multiple industrial interfaces, an integrated LoRaWAN antenna, flexible power options and remote data acquisition capabilities, the UC501 offers an efficient bridge between conventional wired instrumentation and modern wireless IoT platforms.

Important: The controller includes a built-in solar panel. External sensors, additional wiring accessories, an additional external solar panel and a LoRaWAN gateway are not included unless explicitly stated.
