EWIO2-M M-Bus data logger for energy consumption

The EWIO2-M is a powerful data logger for monitoring energy consumption and energy control in buildings, on machines, plants and systems. Two Ethernet ports with a Daisy Chain function are available for chaining additional data loggers and connecting to the LAN network. The system is parameterized, configured, and commissioned through a platform-independent web browser. The M-Bus and Modbus RTU interfaces allow various meters to be read: for example, electricity, water, gas, and heat. Optionally, measured values can be sent from the database (push) or read (pull) via email (SSL) or FTP (SFTP). Simple control functions and tasks in building or industrial automation can be realized via the web interface with the integrated digital and analog I/Os. An integrated µSD memory card expands the EWIO2-M's range of functions to save settings, data, and applications.
