The reliable 24V supply is an important factor for the high availability during plant operation.
To this end, SITOP offers 1-phase or 3-phase basic power supply units with different output power ratings of up to 1000 W and comprehensive certifications, such as ATEX or IECex, as well as MTBF values of more than 600,000 hours in 24-hour uninterrupted duty. These can be customized depending on the individual requirements and plant configuration–from redundant power supply, redundant power supply with selective monitoring of the 24V feeders all the way to redundant power supply with redundant buffering.
The SITOP library is available for preferred power supply concepts with blocks and faceplates for direct integration into SIMATIC PCS 7. The SW blocks in the SIMATIC S7 supply the faceplate on the user interface of the process control system with operating and diagnostics data, generate messages and ensure connection to the maintenance system of PCS 7.
This ensures constant transparency of the 24V supply in the control system. This means that PCS 7 users automatically receive information about operating status conditions (e.g. buffer mode), maintenance requirements (e.g. replacing batteries) and disturbances (e.g. short-circuit or overload in 24V circuits).
Critical plant states are recognized quickly to avoid costs due to failures. The result is a sustainable increase in plant availability.
