Ixxat Smart Grid gateway M-bus

Energy Smart Grid Gateway with M-bus, Modbus, IEC61850 & IEC60870-5-104

The SG-gateway is a remote terminal unit and Smart Grid gateway for the energy market with an M-Bus Master interface for reading up to 64 remote energy meters. In addition, it includes 2 digital S0 inputs and 2 digital outputs.

The IXXAT SG-gateway supports the communication protocols used in the energy sector, e.g. IEC60870-5-104 and IEC61850.
The gateway can also support the connected electric equipment in the field, via an Ethernet interface and/or a serial port, using the protocols Modbus TCP and RTU. As an option, the SG-gateway can include 3G modem.
