The railway protection and control unit (SGBA) facilitates monitoring and control of equipment and installations for DC railway applications.
The SGBA - a modular combination
- protection module
- capacitor trigger
- user-programmable PLC metrology readings
- E/A modules
- Cable monitoring
- Display for visualization and parameter programming
The extensive protection and control functionality is managed by two independent high-performance processors.
The versatile protection functionality of the SGBA can be used to continuously monitor current and voltage for exceeding or falling below parameter-controlled thresholds.
In the event one of the protection functions is tripped, the connected DC switch can be rapidly shut-down with the capacitor trigger integrated into the SGBA. Messages and measurement values can be transmitted to a USB stick via the integrated interface.
The integrated PLC is user-programmable iaw. IEC 61131-3. The runtime license required for this purpose is already implemented in the SGBA.
User-friendly software is available for analysis and diagnostic functions. The software can provide detailed depictions of measurement value curves and is also used to program the parameters for the SGBA.
