what is plc
what is PLC 
Plc or plc controller is basically an board used to programming the machine in a preordely way, likewise i showing in above figures this one is designed for an rac plant,
In this article I will discuss with you the , wiring connection and components of plc, in terms of RAC PLANT
Let's learn about this with an example u need to charge your smartphone so u need to use an charger to charge your phone for continuous supply of voltage
Same in the sense SMPS have same purpose it distribute constant voltage 12/24 voltage around the panel in case your are using module box
MCB- MCB are available in the difference variant in the market , if it's. 100 amp. Plus then it's called as MCCB
THIS IS SERVED IN THE CIRCUIT IF THERES HIGH VOLTAGE OR AMPRE DIFFERENCE JN THE CIRCUIT, IN THAT CASE MCB going to trip it can be single pole or 3 poles
in 4 connection MCB the fourth one is for neutral wire connection.
CONTACTORS - Contractors are basically coins those serves inthe circuit to of & offf the motors , when you turned on/ off the switch,
These are directly connected to the T1.T2.T3 point of the MCB, with each face RYB, RESPECTIVELY
THE A1 &A2 points are for coils to turn on / off,
The start stop switch is added between these two
.
The MCB is really expensive & the compressor & motors repair cost is also high if overload doesn't worked properly the contactor simply burn to safeguard the compressor /motor
Overload , overload is also served for the safety fo contactor as it doesn't have any safety of its own,
