3 Wire Proximity Sensor Connection To Plc

A typical 3 wire dc sensor s output has a rating of 100ma to 200ma.

3 wire proximity sensor connection to plc.

Three wire sensor in plc three wire sensor connection in plc. Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Other examples of a load could be a relay or machine alarm just make sure the load rating of the sensor is not exceeded. The box in the diagram represents the load.

For example we will reference an inductive proximity sensor. The most common type of load would be a plc programmable logic controller dc input. Wire connection of fx3u plc and 3 wire npn proximity sensor npn proximity sensor is characterized as low level conduction its signal flows from the load to the proximity sensor. 2 wire dc pnp 2 wire dc npn 3 wire dc pnp and 3 wire dc npn cases have been covered in this discussion.

But the signal output wire of proximity sensor must be connected to the signal input point of plc so when a npn proximity sensor is connected the signal flows. This sensor is the ck1 00 2h capacitive proximity sensor. If we connect the photoelectric switch to plc input channel 3 the red wire will be connected to 24vdc and the black wire will be connected to. Knowing how to connect a 3 wire dc solid state proximity sensor to a plc programmable logic controller is dependent on the type of proximity sensor and the plc to be used that is specific to the design of the circuit and the preferred application.

There are two basic types of 3 wire proximity sensor applicable to certain types of plc. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. Instead of using a plc to construct a working electrical circuit for a certain application making use of a traditional wiring method is also a mutually exclusive choice which is another workable option when a plc is not available. You will also learn what a 3 wire discrete sensor is and recognize some of the common types of 3 wire discrete sensors.

In our case the plc input will be our load. In this blog post you will learn how to wire a 3 wire dc sensor like an inductive proximity sensor to a plc input card. For a polarized device like the photoelectric sensor care must be taken to connect the positive wire red wire to 24vdc and the black wire to the negative terminal plc input card connection. Here is a wiring diagram of a pnp sensor.
