17-7 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 reso-
lution 1/2,000).
• The analog output signal ranges are 0 to 10 V (with a resolution 1/4,000).
