Analog I/O Units
Using Analog I/O
Writing Set Data and
Reading A/D Converted
Values
Connect and wire the Unit.
Create a ladder program.
CPU Unit
Ladder program
MOV(021)
• Writes the set data.
• Reads the converted
values.
"m" is the last input word and "n" is the last
output word allocated to the CPU Unit or
previous Expansion Unit or Expansion I/O Unit.

• Connect the Analog I/O Unit.
• Wire to analog I/O devices.
• Analog inputs: 0 to 5 VDC, 1 to 5 VDC, 0 to 10 VDC, –10 to
10 VDC, 0 to 20 mA, or 4 to 20 mA
• Analog outputs: 1 to 5 VDC, 0 to 10 VDC, –10 to 10 VDC, 0 to
20 mA, or 4 to 20 mA
• Set analog inputs as voltage or current inputs and set the
averaging function.
• Write set data to output words.
