*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.
*2. The offset and the gain should satisfy the following condition:
1 V ≤ (Gain - Offset) ≤ 10 V
*3. The offset and the gain should satisfy the following condition:
3 mA ≤ (Gain - Offset) ≤ 30 mA
*4. When the external load is less than 30 kΩ, please use the output corrective function by load resistance.
PLC User's Manual - Analog Control Edition
24 V DC ±10 %, 160 mA
(It is necessary to supply 24 V DC from the terminal block.)
5 V DC, 120 mA
(Since the internal power is supplied from the main unit, it is not necessary to supply power
externally.)

1 ms (The number of selected channels will not affect this value.)
• 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.
