REMARK
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".
–
The voltage input range is selected in program.
Input selection switch has to be located at off.
(1)Voltage input range : DC 0 10V
Digital output value for input voltage is shown as follows.
