Voltage Input Range and Converted
Values
Analog voltage input 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.
Input Range: -10 to 10 V
A voltage of -10 to 10 V is converted to a signed integer value (-32000 to 32000).
The resolution is 1/64000.
The input voltage range for which conversion is possible is -10.2 to 10.2 V and the converted value is
a signed integer value (-32640 to 32640).
The disconnection detection function is not supported.

Input Range: -5 to 5 V
A voltage of -5 to 5 V is converted to a signed integer value (-32000 to 32000).
The resolution is 1/64000.
The input voltage range for which conversion is possible is -5.1 to 5.1 V and the converted value is a
signed integer value (-32640 to 32640).
The disconnection detection function is not supported.
