Industrial Cellular Modem GSM InDTU-332
Industrial Cellular Modem InDTU-332
The InDTU 332 Series are modem designed for the sending of serial communications on GSM/ GPRS mobile network. Modems have a compact design and presents high performance with security features and low consumption. The planning used components able to resist in particularly hostile environments for example for high temperature changes from -25 °C to +70°C. O for supply intervals particularly large, from 5V to 35V and strict EMC conditions. The modem can be programmed with different tools among which a powerful software tool or a cloud administration site, the Device Manager. InDTU 332 is a product widespread and compliant with the DL/T 721-2000 standard for the remote control in automation systems for Power Grid. Features:
