The Exa RJ45 H (6 DIN rail or 96×96) is an Energy Analyser & Data Manager with microprocessor (Cortex-M4 Dual Core). The meters are versatile and designed to meet the needs of the most sophisticated industrial, tertiary, public and residential applications for electrical parameter monitoring and power quality management.

The meters have a high accuracy class 0.5S for the Active Energy and the measurements of the single harmonics up to the 51st order are obtained by continuous high resolution sampling the voltage and current waveforms. This ensures the maximum accuracy even in the presence of rapidly variable loads. The Exa RJ45 H is equipped with an RS485 slave port, Ethernet port with an option for Wi-Fi. Depending on the model, the meter can be equipped internally with an input / output card or with an environmental sensor card.

The Exa RJ45 H has a high capacity memory of 128MB which allows for implementation of multiple additional functions through the activation of upgradeable PUK codes. The meters communication architecture allows you to modify the firmware by uploading remotely from the installation.

Exa RJ45 H is also equipped with an expansion bus, ExpBus for the connection of digital and analogue input / output modules. For environmental sensors the meter is equipped with NFC (Near Field Communication) technology.

The Exa net H Web is an Energy Analyser and Web Data Manager. The meter has an open platform which can be connected to Ethernet or Internet via the RJ45 (and Wi-Fi) port. This allows the meter to be used for the continuous monitoring of energy efficiency through the measurement and management of energy parameters (electricity, gas, water, etc.), environmental (temperature, humidity, luminosity, CO2, etc.) and process parameters.

The internal analyser for measuring energy quantity and power quality has a Web server and FTP server. Communication can also be made to other devices via the master RS485 and the ExpBus. The Wi-Fi versions allow you to manage and view data with devices (PC, Smartphone, Tablet) connected to the existing Wi-Fi network from an Internet browser.
