10-5 Analog Input Option Board
Each CP1W-ADB21 Analog Input Option Board provides two analog inputs.
• 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).
Main Analog Input Option Board Specifications
Analog Input Signal
Ranges
Analog input data is digitally converted according to the input signal range as
shown below.
Note
When the input exceeds the specified range, the A/D conversion data will be
fixed at either the lower limit or upper limit.
■
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).
