EMU Professional II 3/100 TCP/IP

The 3-phase energy meter EMU Professional II 3/100 TCP/IP for DIN rail mounting features an integrated TCP/IP interface with meter reading memory. The DIN rail meter has a MID B+D certification and is suitable for energy management according to ISO 50001 as well as energy cost billing.

The 3-phase three-phase meter EMU Professional II 3/100 TCP IP is suitable thanks to the Ethernet interface with Modbus TCP for integration into building control systems and smart home systems such as Loxone.
For integration into Loxone, a driver is available in the Loxone Library.

TCP/IP interface | Modbus TCP

The TCP/IP interface is integrated in the EMU Professional II 3/100 TCP/IP. The network parameters can be configured and the instantaneous measured values can be analysed on the web server. The web interface is password-protected. Connection to the LAN is via an RJ45 connector.
The EMU Professional II energy meter supports Modbus TCP communication.
