9.6.4 System configuration example 1
In this system configuration example using only dedicated flat cables, both the current consumption and the
voltage drop are small.
System configuration example
1) Current consumption calculation
Total current consumption
2) Voltage drop calculation
3) Confirmation related to the minimum operating voltage (20.4V DC) of the module
24V - 2.612V = 21.388V
≥ 20.4V

- The current consumption of each station shall include the
current consumption of the connected I/O equipment.
- It is supposed that the general-purpose power supply
satisfies the required condition.

From 1), 2) and 3) above, the system can be configured using only the built-in
power supply with regard to both the current and voltage restrictions.
