17-6 Analog Output Option Board
Each CP1W-DAB21V Analog Output Option Board provides two analog outputs.
• The analog output signal range is 0 to 10 V (with a resolution 1/4,000).
The analog values depend on the output signal range, as shown in the following diagram.
Note When the output exceeds the specified range, the output signal will be fixed at either the lower limit or upper
limit.
z
0 to 10 V
The hexadecimal values 0000 to 0FA0 (0 to 4000) correspond to an analog voltage range of 0 to 10
V. The entire output range is 10 to 10.24 V.
