Overview

The InDTU 332 Series of rugged industrial cellular digital terminal units (DTU) are designed to transmit serial data over GSM/ GPRS mobile networks. The modems are light-weighted, compact-designed modems combined with rich features of high performance, high security, and low power consumption. And they bases on professional industrial chip design capable to work robustly in harsh outdoor circumstances, for example, wide operation temperature ranging from -25℃ to 70℃(-13~158℉), wide range power input from 5V to 35V and strict EMC conditions. The modems can support several management tools include handheld configuration tool, Device Manager, InAdmin remote configuration tool, which significantly reduce the maintenance and installation cost for customers. InDTU 332 is well proven product approved by high end customers including Siemens, Schneider Electric, China State Grid and etc. And it is compliant with smart grid industrial DL/T 721-2000 Standard of tele-control in Power Grid automation system.
