Pnp Schaltung. Das ergibt sich aus der anordnung der bauteile in deiner schaltung. A pnp device sources or provides 24 v to the input card when active.
This is a demonstration of an npn transistor the emitter is at ground and the base and collector voltages can be controlled using the sliders at right. Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Pnp darlington transistor features this device is designed for applications reguiring extremely high current gain at currents to 1 a.
The pnp transistor has very similar characteristics to their npn bipolar cousins except that the polarities or biasing of the current and voltage directions are reversed for any one of the possible three configurations looked at in the first tutorial common base common emitter and common collector.
Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Npn devices are known as sinking and can switch the negative side. Grundsätzlich sollte im i b und im i c stromkreis ein strombegrenzender widerstand eingesetzt sein. Hast du die möglichkeit die schaltung wahlweise für einen npn oder einen pnp typ auszulegen wählst du die variante mit dem npn typ.
