The SG500 is a fanless embedded communication gateway dedicated to data collection in building energy monitoring systems. It meets the requirements for energy consumption metering and sub-item data collection in national government agencies, large public buildings, industrial enterprises, etc., for various forms of energy such as water, electricity, gas, oil, cooling, and heating. Paired with simple and easy-to-use data configuration software tools, it can quickly configure the required data collection and upload data center parameters. With advanced remote maintenance management functionality, efficient and convenient maintenance of data collector gateways can be achieved.
