## Long description

The Milesight UC300915M is a compact gateway controller for DIN-rail or wall mounting that enables remote monitoring and control of field sensors and devices. It offers multiple industrial interfaces, external antenna connectors, MicroSIM support (cellular versions), and a DC input range of 5–24 V. The device includes LED status indicators and supports cloud integration via TCP/UDP/MQTT to communicate with platforms such as Milesight IoT Cloud and AWS (AWS available for cellular models).
Advantages
The UC300915M integrates diverse industrial interfaces including 4–20 mA, 0–10 V analog inputs and two RTD inputs for 2-/3-wire PT100 sensors, converting resistance signals to 4–20 mA within a wide temperature span (-200°C to 800°C). It provides an intelligent IF–THEN trigger system with up to 16 custom commands, can operate autonomously when the network is unavailable, and uses standard protocols (TCP/UDP/MQTT) for flexible cloud compatibility. External SMA antenna connectors and MicroSIM support simplify deployment in cellular configurations.
Suitable for
Remote monitoring of temperature and analog sensors
Industrial automation and process control
Data collection and timed/condition-based triggers
Edge control where intermittent network connectivity occurs

How to use
Mount the UC300915M on a DIN rail or fixed to a wall and connect the required sensors to the appropriate interfaces (4–20 mA, 0–10 V, or PT100 via RTD inputs). Attach external antennas to the SMA connectors for wireless operation when relevant and insert a MicroSIM card for cellular models. Configure network and cloud settings using the device management interface, define up to 16 IF–THEN commands for automated tasks, and verify LED indicators for system status. The device will continue executing configured commands locally if network connection is lost.
Usage recommendations
For reliable temperature measurement with PT100 sensors, use proper 2- or 3-wire cabling and ensure sensor ranges match the configured scale. When deploying in cellular mode, check network coverage and secure antenna placement. Regularly monitor LED indicators and cloud connection status and back up configuration settings after initial setup.
