Pnp sinking or sourcing
WebAug 25, 2024 · I can use an NPN to make a current sourcing or a current sinking circuit. The same applies to a PNP. So your question's statement that PNPs source and NPNs sink is … WebFirst, sinking vs sourcing. You're looking at where the 24V is going relative to the IO card, so a sourcing output card provides 24V on its outputs and a sinking input card accepts 24V on its inputs. The more useful terms are PNP and NPN and the described sourcing output and sinking input are the standard PNP.

This document is meant to give a solid understanding of these concepts, a nd clear up the definition issues of Sinking (NPN), and Sourcing (PNP), from both a technical and terminology perspective. In general, Sinking (NPN) and Sourcing (PNP) are terms that define the control of direct WebMar 6, 2024 · If a device sends current out, we call it ‘sourcing’. Therefore a PNP sensor is also called a ‘sourcing’ sensor. This is easy to remember because the sensor is the source …
WebJul 2, 2013 · I have been reading that NPN transistors are sinking and PNP are sourcing devices. I do not really understand this concept. It says current source device connects … WebSep 19, 2024 · With the KL1408, since it is sinking, you need a switch that would source. Think of the sourcing device as the one that supplied a positive current flow. The device it connects to will need to be the opposite (sinking) in order to accept the positive current flow. The PNP will supply a positive.
WebJul 30, 2024 · PNP transistors (sometimes called "sourcing sensors") performs the same job, but is set up so that a negative voltage must be applied to the base pin to allow current to flow from the emitter to the collector lead. ... NPN, or “sinking” output sensors, work in the opposite way, sinking ground voltage to an input when it’s on. The base ... WebNPN (Sinking) and PNP (Sourcing) are two types of transistors used for digital outputs. The terms Sinking and Sourcing refer to current flow with respect to the terminal pin on the IO …
