Expanded RS485
Interface Connectivity

The RS485 interface of the UC300 allows for connectivity with 32 channels, enabling the connection of 32 field sensors or devices. This feature establishes the UC300 as a central hub for comprehensive sensor data management and industrial IoT automation.

Temperature Transmitter

Besides the 4~20 mA & 0~10 V type analog interfaces, the UC300 firstly adopts 2 RTD inputs for accepting and converting 2/3 wires PT100 sensors' resistance signal into 4-20 mA current signal with a range from -200°C to 800°C.

Intelligent Trigger System

Users are able to set up 16 commands based on custom trigger conditions & actions to realize intelligent tasks like timing data collection.

Autonomous Operation

Milesight UC300 IoT controller can execute the commands autonomously even when the network is unavailable.


The UC300 IoT Controller supports global LoRaWAN® frequency plans or 4G LTE as backhaul connectivity to meet different projects.

Flexible Cloud Integration

Support TCP/UDP/MQTT protocol, UC300 IoT controller is compatible with multiple Cloud platforms such as AWS (for cellular version only) and Milesight IoT Cloud.
