configuration and wiring length design.
Calculate current consumption.
Refer to 9.6.3-1
Total current
consumption of remote I/O
stations that receive power
from built-in power
supply ≤ 0.35 A
Check simplified graph or calculate
voltage drop.
Refer to 9.6.3-2
Is voltage drop ≤ 3.6 V
Minimum operating voltage
(20.4 V) for each module shall be
assured.
Power supply voltage
- Voltage drop ≥ 20.4V
Select general-purpose power supply.
