Multi connectivity in industrial and energy automation with cloud connection – in one small device

The SG-gateway supports the communication protocols used in the energy sector, including IEC60870-5-104 and IEC61850, and enables connectivity for numerous different energy devices in different networks. On top of that, the simultaneously usable OPC-UA and MQTT functionality empower direct integration into the companies’ cloud-based applications.

Retrofitting of existing assets

The SG-gateways enable easy retrofit of existing switchgear and other components to your protocol of choice.

The 4-port switch enables routing of any of the Ethernet-based protocols between 2 separate IP networks. The EtherNet/IP interface for Allen-Bradley PLCs is a real-time adapter interface with an integrated 2-port switch that enables seamless network integration.

By combining EtherNet/IP, 4-port switch, another Ethernet interface, and a serial interface, the SG-gateway offers enormous flexibility in network design and cyber-security through the simple and secure separation of the different network segments. In addition to the IEC61850 and IEC 608710 protocols, other electric equipment in the field can also be connected via Modbus TCP and RTU.

Easy configuration

A user-focused interface with no need for programming knowledge or external software makes this the perfect multitool in the field of communication within energy distribution applications.

Technical service

If you need help with the energy protocol configuration, our excellent technical service department is at your side during the whole project.
