2.4.2 G4F-AD2A I/O Characteristics
1) Voltage Input Characteristics
- The G4F-AD2A is capable of selecting voltage/current and adjusting offset/gain for each channel.
- For voltage input, the input conversion switch may be set to the range such as from-10 to 10 VDC, or
from -5 to 5 VDC.
a) -10 ~ 10 VDC
Position of input range switch
- When offset/gain setting is changed, digital output value to voltage input characteristics are as below.
