Ixxat Smart Grid gateway Switch

Energy Smart Grid Gateway with 4-port switch, Modbus, IEC61850 & IEC60870-5-104

The SG-gateway with integrated switch is a remote terminal unit and Smart Grid gateway for the energy market. The 4-port switch enables routing of any of the Ethernet-based protocols between 2 separate IP networks.

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.
