Ranges
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).
Voltage Input
0 V to 10 V
0 V to 15 V
200 kΩ min.

Not supported
Inner sample time 2ms/point
Refresh time > 6ms basing on baud rate and PLC cycle time
None
5 VDC: 20 mA max.
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).
