The power module receives the system’s incoming electrical supply and provides the appropriate regulated power required by the PLC rack. The backplane then distributes the available operating power to compatible modules installed in the rack.
During normal operation, the power supply performs several important functions:
- Converts incoming electrical power into suitable PLC operating power
- Supplies the Series 90-70 backplane
- Supports CPU module operation
- Powers compatible I/O modules
- Supports communication module operation
- Maintains stable internal power distribution
- Helps protect the PLC system from abnormal electrical conditions
- Supports continuous industrial control operation
Reliable power delivery is particularly important in applications where PLC downtime can interrupt production or affect critical process operations.
