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.

[Fig 2.1] I/O Conversion Characteristics

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 exceed +15V and 25mA.
