*2 The measurement data are returned in an integer value 0 - 16777215.
When converting the measurement data into voltage or current values, use the following conversion
formula.
Conversion formula:
Input voltage (V) = Measurement data x Span / 2
Input current (mA) = Measurement data x Span / 2
Analog input range
±10V
±5V
±2.5V
0-10V
0-5V
±0mA
0-20mA
The table below is the conversion example when analog input range is set to "±10V".
Input voltage (V)
+9.999998
+0.000001
+0.000000
-0.000001
-10.000000
*3 The voltage value (V) or current value (mA) is returned in single-precision floating- point number type.
For example, if the input voltage is 1.5V, "1.5" will be set.
This is supported when using firmware Ver1.30, and with definition information Ver1.1.0.0 or later versions
for the CPSN-AI-2408LI.
When the firmware is Ver1.20 or earlier versions, use the Ver1.0.0.0 definition information.
