Hello guys,
I need more some clarification on wiring sensors.
From what I have read this is what I understand: Typically an NPN sensor has the collector wired to the input of the PLCs which makes it "Sinking'
A PNP Sensor has the Emitor wired to the input module which makes it Sourcing
My questions: Is it possible or even common to have a NPN Sourcing and PNP Sinking. It is my understanding that Terry uses a NPN Sourcing? Therefore, Should I be more specific when ordering sensors i.e. NPN (Sourcing or Sinking) I hope this does not make the matter more confusing!
Thanks
