Input / Output (hereafter I/O) conversion characteristics are expressed with the angle of the line between
analog input(voltage and current) and matched digital value.
I/O conversion characteristics of the G3F-AD3A, G4F-AD3A are expressed with Fig 2.1, and I/O conversion
characteristics of the G6F-AD2A is expressed with Fig 2.2
The voltage or current input for a channel is selected by analog input selection switch and the value of
Offset / Gain can not be changed because it is fixed.

REMARK
1. The analog output value of over 4047 or –48 is fixed as 4047 or –48.
2. Keep the input voltage and current not to 15V and 25mA.
