• Output power for PLC can vary depe...read more

PLC can use both AC and DC current depending on the application.

• PLC can use DC current for low voltage applications.

• PLC can use AC current for high voltage applications.

• The type of current used depends on the input/output modules and power supply used.

• PLC manufacturers provide specifications for the type of current to be used.

• Examples of PLCs that can use both AC and DC current include Siemens S7-1200 and Allen-Bradley CompactLogix.
