Since your base never gets lower than 4.3V (5v - 0.7v VBE drop), it will never turn off. This is also why you see ~4.3V when IN is floating. The leakage current through the VBE diode is enough to cause this, and can also keep the transistor on by itself.

WebDec 28, 2024 · PNP Relay Switch Circuit As well as switching relay coils and other such loads with NPN Bipolar Transistors, we can also switch them using PNP Bipolar … WebOne relay module comes with an NPN transistor whereas another module comes with a PNP transistor. If the relay module uses an NPN Transistor, then it will activate the relay by applying an active high signal to the control pin. Alternatively, if a PNP is used then the relay will be activated through an active low signal on the control pin.
WebWhen an object intrudes into the light curtain field-of-view, the light curtain switches off its two PNP outputs (OSSDs). The safety relay responds by opening its two output relays. This removes 24V from the coils of the two safety contactors whose contacts open and remove power to the motor. The motor coasts to a stop category 0. WebJul 18, 2010 · The relay will be powered from 29.4V and has a resistor in series to give the appropriate 24V for the relay. And of course there is a diode over the relay.
