What is source and sink input wiring in plc?

Input or output values ​​of a PLC controller is understood the circuit diagram explained.  It would be clear that ever sensor is Sourcing type that the input module required would be singing type sensor is a singing type the model will be a source inside when the sensor used condition.  It acts as a cloth storage and fault condition that acts as an open switch.

Sensors and actuators how are you to the input output module of PLC we need to understand the concept of Sourcing and thinking this is required to appropriate to select the sensors actuators as well as other cards for the PLC and effect diagram shown here.  We can see a power source and a switch and lamp in series with that when the switch is closed current circuit and love turns on as we can observe current force and was the switch and then the lamb here it is it Sourcing type.

 positive of Call Centers will be connected to be positive point on the module and output of different sensors will be connected to the individual points for the input module sensor is triggered current flows into the sensor as shown in the animation and then into the input module  and the input module as I was thinking the same and logi can use for outsourcing type input module when using a Sourcing type input module that should be taken to connect the common for all the center to the ground terminal of the module understanding the concept of Sourcing  and sinking will help us to select the sensors and actuators.  Probably for the project as well as they are you model of a PLC.
