Using a SITOP power supply as an alternative to a load power supply
Alternatively, an external 24 V power supply from the SITOP range
(https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/10008864) (SITOP smart or
SITOP modular) can be used:
• With redundant installation
(https://support.industry.siemens.com/cs/ww/en/view/109768676) of the 24 V power
supply as protection against failure of a power supply unit
• With buffering of the 24 V power supply (e.g. with DC UPS) as protection against power
failure
• With selective monitoring of 24 V loads as protection against overload or short-circuit
