Simultaneous Voltage and Current Input Characteristics
1) G3F-AD3A, G4F-AD3A
For simultaneous voltage and current input, the input conversion switch of each channel is set to corresponding
voltage and current range.
Ex) Voltage input range: 0 to 3 Current input range: 4 to 7
- Digital output value for analog input is shown as follows..
