Pnp Wiring Diagram. Here in this condition vout vin vbe1. World beam qs18 2 wwwbannerengineering.
For example the collector emitter voltage must be negative for the pnp type to make current flow from the emitter to collector. Here is a wiring diagram of a pnp sensor. Therefore the relay control module must be placed above the motor or on the wall of the coach in close enough proximity to the motor that the 10 motor lead will reach.
Therefore the relay control module must be placed above the motor or on the wall of the coach in close enough proximity to the motor that the 10 motor lead will reach.
So 3v is connected to the emitter of the transistor. Referring to the npn wiring diagram above note that the sensor supply voltage and the high side of the load are connected to the same point and are therefore at the same voltage. Sensor wire is run straight to plc input. The pnp relay switch circuit needs different polarity of operating voltage.
