Compact M-Bus intelligence
The little sister of the WebLog250 now brings the full convenience and performance also to smaller installations. The M-Bus logger WebLog120 has an integrated web server, 4GB memory and adapts to your needs as flexibly as the WebLog250. The WebLog120 can supply M-Bus 120 meters with power and voltage and manage up to 1,000 meters. With the help of the implemented database, your data can already be structured individually in the central unit.
A particularly convenient function is the automatic export of the read data via email or FTP upload. In addition to the standard interfaces (USB, RS232C, Ethernet, RS485, repeater), WiFi is also available as an option. Thanks to the integrated double LAN interface and the repeater input, very individual installations can be realized, for example with a second controller or with a second M-Bus master.
Remote access to the WebLog120 is done via a web browser. Up to 120 terminals can be managed.
