net-line BCU-50

Sturdy and stable substation automation

Bay station controllers in the electrical power supply must withstand special environmental requirements, especially when the station automation is used in high-voltage equipment, strongly vibrating or shock generating system components or also in environments with a seismic risk. We have therefore an extremely sturdy bay station controller with the net-line BCU-50, which fulfils the requirements of modern substation automation. Like all products from SAE IT-systems, the BCU-50 is also distinguished by high functionality and durability as well as tremendous performance.

Application areas

A series of powerful functional modules forms the basis of the numerous possibilities for using the BCU-50. These include for example convenient cross-connection (of information between different telecontrol stations), as well as the integration of external components (for instance protective device coupling via IEC 61850 or IEC 60870-5-103). The main application fields of the BCU-50 are:

  • Station and bay controller in medium and high-voltage switchgears
  • Gateway and communication router between station buses, field bus and control systems
  • Monitoring and control unit for the utilities, waste management and manufacturing industry

Same as at its brother FW-50, a particular strength of BCU-50 lies in the implementation of communication tasks with substations and control systems of many different manufacturers.
