Integrating multiple and various kind of industrial interfaces for monitoring and control field sensors or devices simultaneously. 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. Users are able to set up 16 commands based on custom trigger conditions & actions to realize intelligent task like timing data collection. Milesight UC300 IoT controller can execute the commands autonomously even when the network is unavailable.
