EEM-EM375 / EEM-EM377
The EEM-EM375 and EEM-EM377 are three-phase MID-certified energy meters with an Ethernet interface. The EEM-EM375 measures through current transformers (1 A / 5 A secondary), the EEM-EM377 measures directly (up to 80 A). The Controller communicates with them over Modbus TCP on port 502.
- Configure the network settings (IP address / DHCP), and on the EEM-EM375 the current transformer ratio, through the meter's integrated web server.
- Make sure the meter is reachable from the Controller over the local network.
The other meters of the EEM-EM/DM3xx family are not supported: the EEM-EM355, EEM-EM357, EEM-DM357 and EEM-DM357-70 only have an RS-485 (Modbus RTU) interface, and the EEM-EM325 and EEM-EM327 only have an M-Bus interface.
