1. The analog output value of over 4047 or –48(2047 or –2048) is fixed as 4047 or –48(2047 or –2048).
2. Keep the input voltage and current not to exceed +15V and 25mA.

2.4.1 Voltage Input Characteristics

1) G3F-AD3A, G4F-AD3A
For voltage input, the corresponding input selection switch of each channel should be set to "off".
- Off : Voltage
The voltage input range is selected in program.
–
Input selection switch has to be located at off.
