With all due respect, your question does not make sense. The 9403 takes a voltage input. If the voltage is over a certain threshold (2.7VDC I believe) you read a '1'. If the voltage is under a certain threshold (0.7VDC I think) you read a '0'. The 9403 has 32 such channels that can input or output voltage. In practice the channels are dedicated to specific purposes (PWM, Digital I/O, Relay I/O, I2C etc).
Do you want to input an analog voltage and determine the absolute value? The 9201 module has 8 channels of analog inputs (1 is taken up by the battery measurement).
There are manuals for the devices on the breakout modules online at
