NAND Gate Logic in PLC

PLC NAND Gate 

• We representing a NAND Logic Gate with two Inputs A and B.

  

  NAND Gate

• NAND Gate provide same result is to put NOT gate on each Input and Follow with OR Gate.

NAND Gate Truth Table :

Inputs		Output
A	B
0	0	1
0	1	1
1	0	1
1	1	0

 

PLC NAND Logic :

• When Input A AND B are both off is there an output on.
• When Input A AND B are both are not 1 is there an output on.
