[Fig 2.1] I/O Conversion Characteristics

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.
