*1. Adjustment of the offset or gain value will not affect the resolution. In the direct indication mode,
however, the offset/gain cannot be adjusted.
*2. The offset and the gain should satisfy the following condition:
1V ≤ (Gain - Offset)
*3. The offset and the gain should satisfy the following condition:
3 mA ≤ (Gain - Offset) ≤ 30 mA
*4. If 1 or more channels use the digital filter(s), the time required for A/D conversion will be
"5 ms × number of selected channels."

24V DC ±10%, 90mA
(It is necessary to supply 24V DC from the terminal block.)
5V DC, 110mA
(Since the internal power is supplied from the main unit, it is not necessary to supply power
externally.)
24V DC ±10%, 80mA
(It is necessary to supply 24V DC from the power connector.)
5V DC, 100mA
(Since the internal power is supplied from the main unit, it is not necessary to supply the power.)

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