Application 1 - PLC Controlled Analog Multiplexer

• Various use of multiplexer with PLC has been introduced.
  
• 6 x digital channel and 1 x analog channel used by the PLC to make this multiplexer work.
• In this example the analog inputs are 4 - 20mA none floating loops.
• The 1 x analog output to the PLC is 2-10VDC.
• 74HC/HCT4067 is the 16ch analog multiplexer/demultiplexer circuit used in this example.
