Hello Friends, in this video i have Discuss PLC Fundamental Wirnig and also we learn Sink and Source.

1. PLC Fundamental
wiring
and Sink/Source

2. PLC Fundamantel
• What Is PLC ?????
Programmable Logic Controller
Hardware
- Ladder Logic
- FBD
- SFC
Reprogramming
• Let's come next page how to use thsi system parcticaly

• Example:- Water Level Control

• 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.
• This Fundamantel 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

• If input 24v
then we gives

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
