Milesight DI/DO Controller CTRL-UC300

Milesight DI/DO Controller CTRL-UC300 The UC300 series is an IoT controller designed for remote monitoring, control, and data collection across a wide range of devices. It features multiple I/O interfaces, including analog inputs, digital inputs, relay outputs, serial ports, and PT100 RTD inputs, enabling flexible device connectivity. Data transmission is supported via LoRaWAN. The UC300 also supports configurable trigger conditions and automated actions, allowing it to operate independently even during network interruptions. When integrated with the Milesight IoT Cloud platform, users can conveniently monitor and control connected devices through a web interface or mobile application. Built with an industrial-grade design and housed in an IP30-rated metal enclosure, the UC300 is well-suited for indoor applications such as smart factories and building automation systems. Compatible with a wide range of wired devices via DIO, AI, RS232, RS485, and PT100 RTD interfaces Supports wireless communication over LoRaWAN Enables multiple trigger conditions and automated actions Integrated watchdog ensures stable and reliable device operation Durable industrial metal enclosure designed for a wide operating temperature range Fully compliant with standard LoRaWAN® gateways and network servers Seamless device management through the Milesight IoT Cloud platform Specifications Wireless Transmission Technology: LoRaWAN LoRaWAN Antenna Connector: 1 × 50 Ω SMA (center pin: SMA female) Frequency Bands: CN470, IN865, EU868, RU864, US915, AU915, KR920, AS923-1&2&3&4 Transmit Power: 16 dBm (868 MHz), 22 dBm (915 MHz), 19 dBm (470 MHz) Sensitivity: -137 dBm (at 300 bps) Mode: OTAA / ABP Class C Cellular Antenna Connector: 1 × 50 Ω SMA (center pin: SMA female) SIM Slot: 1 × Micro SIM (3FF) Application Modes: TCP, UDP, MQTT, AWS, Milesight IoT Cloud, SMS Data Interfaces Interface Type: 3.5 mm terminal block I/O Ports: 4 × DI + 2 × DO Digital Input: Opto-isolated, 3–24 VDC (pulse counter supported) Digital Output: SPDT relay, 3A @ DC max 30 V / AC max 250 V Serial Port Ports: 1 × RS232 + 1 × RS485 Baud Rate: 1200–115200 bps Protocol: Transparent (RS232), Modbus RTU (RS485) Analog Input Ports: 2 × 4–20 mA + 2 × 0–10 V Resolution: 12-bit Analog Input (RTD) Ports: 2 × PT100 RTD inputs Input Connections: 2/3-wire Resolution: 12-bit Temperature Range: - 200°C to +800°C Other Configuration Port: 1 × Type-C LED Indicators: 1 × System, 1 × ACT Built-in Functions: Watchdog, Timer Physical Characteristics Power Connector: 3.5 mm terminal block Power Supply: 5–24 VDC Material & Colour: Black metal enclosure Ingress Protection: IP30 Operating Temperature: -20°C to +60°C (-4°F to +140°F) Relative Humidity: 0% to 95% (non-condensing at 25°C / 77°F) Dimensions : 93 × 70 × 22 mm Installation: Desktop, wall mounting, DIN rail mounting
