Energy Distribution

Retrofitting and interconnectivity

With Ixxat SG-gateways, existing systems, new equipment and control systems can be connected to each other in a smooth and fast way – regardless of communication technology or manufacturer brand. 

Energy distribution application


Retrofitting of
existing assets

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


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.

SG-gateway with I/O

Remote control for Smart Grid applications

The SG-gateway supports the communication protocols used in the energy sector, including IEC60870-5-104, DNP3 and IEC61850 and enables connectivity for numerous different energy devices. On top of that the simultaneously usable OPC-UA and MQTT functionality empower direct integration into the companies’ cloud-based applications.

The I/O interface enables integration of any 24 V controlled device into energy communication systems.

In addition to the I/O interface and the IEC and DNP3 protocols, other electric equipment in the field can also be connected via Modbus TCP and RTU. As an option, the SG-gateway can also include a 3G modem for remote connectivity.

Order codes: ASG1015, ASG1014, ASG1012, ASG1010, ASG1008, ASG1006, ASG1004, ASG1002, ASG1000

Configuration interface

The application logic can be realized on the device either using the integrated graphical web editor or by using a predefined configuration loaded to the device. The graphical web editor is a very intuitive and easy to use interface to program software applications and configure the gateway. No engineering tools are required, and it can easily be accomplished by service technicians.
