*1. Adjustment of the offset or gain value will not affect the resolution. In the analog value specification
mode, however, the offset/gain cannot be adjusted.
*2. The offset and the gain should satisfy the following condition:
≤ (Gain - Offset) ≤ 10V
1V
*3. The offset and the gain should satisfy the following condition:
≤ (Gain - Offset) ≤ 30mA
3mA
*4. Adjustment of the offset or gain value will not affect the resolution.

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