4.2.3 FX3U-4DA
*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:
1V ≤ (Gain - Offset) ≤ 10V
*3. The offset and the gain should satisfy the following condition:
3mA ≤ (Gain - Offset) ≤ 30mA
*4. Adjustment of the offset or gain value will not affect the resolution.

Same accuracy for 4mA to 20mA output
Ambient temperature:
0 to 55°C±0.5%(±100mV) for 20V full scale ±0.5%(±100μA) for 20mA full scale
Same accuracy for 4mA to 20mA output
Reference Includes corrective function by load fluctuation. -
Time required for D/A
conversion 1ms (The number of selected channels will not affect this value.)
Output characteristics
Insulation method
• 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.
