Input B
1. Disabled, MODE = 0
It is recommended to disable any inputs that aren’t being used. Putting a “0” in the mode for an input disables it.

2. Positive On/Off, MODE = 1
This puts the input into the standard discrete positive
operation mode. When a positive voltage is present
on the input pin, the low bit will turn on.

3. Ground On/Off, MODE = 2
This puts the input into the standard discrete ground
operation mode. When a ground is present on the
input pin, the low bit will turn on.

4. 4-20mA, MODE = 3
This puts the input into 4-20mA mode with a value of 4,000 - 20,000 = 4000 - 20,000 macro amps. A word is allocated for this input. The 1st byte is
the low byte and the 2nd byte is the high byte.

5. 0-5V DC, MODE = 4
This puts the input into 0-5V DC mode with a value of 0 - 5,000 = 0 - 5,000mV. A word is allocated for this input. The 1st byte is the low byte and the
2nd byte is the high byte.

6. 0-10V DC, MODE = 5
This puts the input into 0-10V DC mode with a value of 0 - 10,000 = 0 - 10,000mV. A word is allocated for this input. The 1st byte is the low byte and
the 2nd byte is the high byte.

7. 0-32V DC, MODE = 6
This puts the input into 0-32V DC mode with a value of 0 - 32,000 = 0 - 32,000mV. A word is allocated for this input. The 1st byte is the low byte and
the 2nd byte is the high byte.

8. Ratiometric, MODE = 9
This puts the input into Ratiometric mode with a value of 0 - 1,000 equaling 0 - 100.0%. This input will show the percentage of voltage being read
compared to the source voltage The 1st byte is the low byte and the 2nd byte is the high byte.
