Description

The Milesight UC300 4G is a rugged Cellular IoT Controller engineered for comprehensive remote monitoring and control in environments without access to local gateways. By leveraging 4G LTE technology, this controller acts as a powerful industrial RTU, aggregating data from Modbus devices, analog transmitters, and digital sensors. Its integrated PT100 RTD inputs and extensive I/O density make it the definitive choice for sophisticated industrial telemetry, providing a stable link between field assets and the cloud.

Industrial Multi-Interface Intelligence

Edge Logic Autonomy Supports autonomous IF-THEN triggers and timers, allowing the controller to execute local relay actions and alarms independently of network availability.
Standardized Cloud Integration Fully compatible with AWS IoT, MQTT, and Milesight IoT Cloud, facilitating rapid deployment and visualization of complex industrial sensor data.

Professional Cellular Monitoring Scenarios

• Remote Site Management: Monitor off-grid telecommunication stations or substations via 4G where no LoRaWAN coverage exists.
• Precision Thermal Control: Utilize PT100 RTD inputs to track temperature stability in industrial furnaces or large-scale cold storage.
• Water Distribution: Track analog pressure and flow sensors while managing pump cycles using the integrated digital inputs and relay outputs.
