*1.
Adjustment of the offset or gain value will not affect the resolution. In output mode 1 or 4, however, the
offset/gain cannot be adjusted.
offset/gain cannot be adjusted.
*2.
The offset and the gain should satisfy the following condition:
1V
1V
≤ (Gain - Offset) ≤ 10 V
*3.
The offset and the gain should satisfy the following condition:

Insulation method
• The photocoupler is used to insulate the analog output area from the PLC.
• The DC/DC converter is used to insulate the analog output area from the power supply unit.
• Channels are not insulated from each other.
