Carlo Gavazzi Inc. launched a new line of modular monitoring systems for energy management. VMU-C EM is a data logger system for small to medium projects, VMUC-Y EM is a hardware data aggregator for medium to larger projects and Em2 Server is a software solution for large projects. They are designed to complement the extensive line of Carlo Gavazzi energy maters and current transformers.
The VMU-C EM is a combination of hardware modules, whose primary function is to collect data from a network of energy meters and environmental sensors and then make this data available to end users utilizing industry standard methods, such as integrated web server, FTP, HTTP and Modbus/TCP data transfers. In addition to data management, the VMU-C EM platform can provide a relay output, SMS or email alarms and scalable pulse rate inputs. The VMU-C EM can function as a standalone data logging solution for applications with up to 32 meters or as a data gateway for larger installations.
The VMU-Y EM is a data aggregator that is built upon the VMU-C EM hardware platform, with a primary function of aggregating data from a network of VMU-C EM data loggers in applications where support for more than 32 energy meters is required. The VMU-Y EM relies on VMU-C EM data loggers to collect the data from energy meters and environmental sensors, but it is also responsible for the management of collected data and web server function. Up to 10 VMU-C EM / 320 meters can be managed by single VMU-Y EM.
The Em2 Server is a software solution provided as a Virtual Machine software appliance to be hosted either in a customer’s facility or remote server. Similar to the VMU-Y EM, the Em2 Server relies on the VMU-C EM for communication with energy meters. It aggregates data in large applications with up to 100 VMU-C EM loggers / 3,200 energy meters and provides web server function.
