2.3 Performance Specifications
*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 k
Ω
, please use the output corrective function by load resistance.
→ For a detailed description of the output corrective function by load resistance,
refer to Subsection 5.4.17.

D/A conversion
circuit drive power
24 V DC ±10 %, 160 mA
(It is necessary to supply 24 V DC from the terminal block.)
CPU drive power
5 V DC, 120 mA
(Since the internal power is supplied from the main unit, it is not necessary to supply power
externally.)

Time required for
D/A conversion
1 ms (The number of selected channels will not affect this value.)
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.
Number of I/O
points occupied
8 points (Taken from either the input or output points of the PLC.)
