Pnp Schaltung Sensor. We will now look at wiring an npn and pnp inductive proximity sensor to the click plc. When used in a traditional relay type control circuit it is normally possible to use either the pnp or npn type.
The pnp and npn sensors are 3 wire dc devices. We will now look at wiring an npn and pnp inductive proximity sensor to the click plc. The third thread connects to the load.
864 848 9569 series parallel connection for npn or pnp sensors.
First select a sensor that matches your plc input card discrete dc input and has the same circuit wiring type pnp or npn. 864 848 9569 series parallel connection for npn or pnp sensors. The difference is in the type of transistor used in the sensor. When used in a traditional relay type control circuit it is normally possible to use either the pnp or npn type.
