Protecting against longer power failures
Sudden and longer failures of the line supply voltage can result in undefined states and
significant danger as a result of the associated failure of the plant or system control. The
SITOP power supply product portfolio includes various DC-UPS solutions to prevent the
failure of the 24 V power supply voltage.
Power supply failures up into the minutes range can be buffered using the maintenance-free
SITOP UPS500 DC-UPS modules based on capacitors (Figure 9-7 24 V buffering to allow
the saving of process data and controlled shutdown of PCs (Page 52)).

Using the free-of-charge SITOP DC-UPS software tool, DC-UPS systems can be simply
integrated into PC-based automation solutions. This supports further processing of the status
signals and safely running down the PC.
