Input Range and Converted Values
Input analog signals are converted to digital values according to the input range shown below.
If the input range exceeds the value range for which conversion is possible, the converted value is fixed
at the upper or lower limit.
z
1/8000 Resolution
A voltage of -10 to +10 V is converted to a signed integer value (-4000 to +4000).
The input voltage range for which conversion is possible is -11 to +11 V and here the converted
value is a signed integer value (-4400 to +4400).
There is no disconnection detection function.
z
1/30000 Resolution
A voltage of -10 to +10 V is converted to a signed integer value (-15000 to +15000).
The input voltage range for which conversion is possible is -11 to +11 V and here the converted
value is a signed integer value (-16500 to +16500).
There is no disconnection detection function.
