The document explains the fundamentals of Programmable Logic Controllers (PLCs), including various hardware components, input types, and output configurations. It discusses the concepts of sink/source in relation to current flow, and details different sensor types such as PNP and NPN sensors. The document also outlines the characteristics of transistor and relay type outputs used in PLC applications, emphasizing their suitability for different load capacities.

• This System INPUT is User level
requirment like 50% ,80% ,20%.
• And Output is solenoid valve
• This All system runing in
processor means this work on
PLC.so this is functioning of PLC.

4. PLC INPUT Wiring
What is Sink and Source:-Sink and source refer to the direction
of current flow between an I/O point on an I/O module and the connected
device. It is only relevant for DC circuits with positive and negative
polarities since current flows both directions in an AC circuit.more

10. PLC OUTPUT Wiring
Hear Is Two Types Of PLC output.
Transistor Type
Output
Relay Type
Output
 Transistor type PLC output capcity 0.1A as per PLC
configuration so we can not use havy load out put.
 If you want to use havy load output in transistor type
plc you can use external rely then we use havy load
output.
 Transistor type PLC mostly use in high speed
application.e.g Servo motor,steppar motor etc.
 Relay Type PLC have 1A to 10A capacity so we can
directly use havy load output.
 its was used in genral purpos
motor,contector,solenoid valve application
