Railway power distribution

 

The high capacity utilization of railway network segments up to the highest load limit makes maximum availability of energy supply critical. In order to best prevent breakdowns and minimize downtimes, systems must be monitored and controlled centrally.

SG-gateway Core

Serial to Ethernet-based communication

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

In addition to 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: ASG3015, ASG3014, ASG3012, ASG3010, ASG3008, ASG3006, ASG3004, ASG3002, ASG3000

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.
