PLC Sinking and Sourcing Explanation
PLC Sinking and Sourcing describes a current signal flow relationship between field input and output devices in a control system and their power supply.
Sink or Source? Normally Open or Normally Closed?
We discuss concepts of Sink or Source used in electrical circuits or in PLC wiring. Also we deal with basics of normally open contact or normally closed contact.
