Current sourcing pnp outputs are internally connected to the power supply voltage and so should be wired externally to a load that has a connection to dc ground. 16 point dc input module.
Wiring A Capacitive Proximity Npn Pnp Sensor To The Click Plc
Pnp proximity sensor wiring diagram. The box in the diagram represents the load. In our case the plc input will be our load. Connection diagrams for 3 or 4 wire sensors will also show the required wiring configuration for their type of output. You will notice that the load appears between the 0v blue and switching wire black. The 0v blue will be attached to the common input and the switching wire black will be attached to the input number. If the inductive proximity sensor is wired incorrectly.
Wiring diagrams show the hook up offour sensors with npn and pnp outputs. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor. 3 wire and 4 wire dc. That is why we always have to refer to the manufactures wiring diagram. The following is a wiring diagram of an open collector pnp sensor.
Here is a wiring diagram of a pnp sensor. When connecting to the plc the plc input acts as the load. Normally open sensor will work normally open wiring diagram for npn and pnp 3 wire sensors with the d2 16nd3 2 technotes product group. Industrial sensors of all types have connection diagrams. This sensor is the ck1 00 2h capacitive proximity sensor. 205 series information type.
Some sensors have pnp and npn as well as no and nc output contacts. The sensor led will stay on and go off when activated. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.
