10-7 Analog I/O Option Board
Each CP1W-MAB221 Analog I/O Option Board provides two analog inputs
and two analog outputs.
• The analog input signal ranges are 0 to 10 V (with a resolution 1/4,000)
and 0 to 20 mA (with a resolution 1/2,000).
• The analog output signal ranges are 0 to 10 V (with a resolution 1/4,000).
Main Analog I/O Option Board Specifications
Analog I/O Signal
Ranges
The analog values depend on the I/O signal ranges, as shown in the following
diagrams.
Note
When the input exceeds the specified range, the A/D conversion data will be
fixed at either the lower limit or upper limit.
When the output exceeds the specified range, the output signal will be fixed at
either the lower limit or upper limit.
Analog Input Signal
Ranges
■
0 to 10 V
The 0 to 10 V range corresponds to the hexadecimal values 0000 to 0FA0 (0
to 4000). The entire data range is 0000 to 0FFF (0 to 4095).
