Current Consumption for Power Supply Units

■ Checking Current Consumption and Power Consumption

After selecting a Power Supply Unit based on considerations such as the power supply voltage, calculate the current and power

requirements for each Rack.

Condition 1: Current Requirements

There are three voltage groups for internal power consumption: 5 V, 26 V, and 24 V.

• Current consumption at 5 V (internal logic power supply)

• Current consumption at 26 V (relay driving power supply)

• Current consumption at 24 V (power supply output terminals) (C200HW-PA204S only)

Condition 2: Power Requirements

For each Rack, the upper limits are determined for the current and power that can be provided to the mounted Units. Design the system

so that the total current consumption for all the mounted Units does not exceed the maximum total power or the maximum current

supplied for the voltage groups shown in the following tables.

●CPU Racks and Expansion Racks

The maximum current and total power supplied for CPU Racks and Expansion Racks according to the Power Supply Unit model are

shown below.

Note1:For CPU Racks, include the CPU Backplane and CPU Unit current and power consumption in the calculations.

2: For Expansion Racks, include the Expansion Backplanes current and power consumption in the calculations.

Conditions 1 and 2 below must be satisfied.

Condition 1: Maximum Current

(1) Total Unit current consumption at 5 V ≤ (A) value

(2) Total Unit current consumption at 26 V ≤ (B) value

(3) Current consumption for service power supply at 24 V ≤ (C) value (Only when using the service power supply from the

C200HW-PA204S.)

Condition 2: Maximum Power

(1) x 5 V + (2) x 26 V + (3) x 24 V ≤ (D) value

■ Example: Calculating Total Current and Power Consumption

Using the CX-Programer to Display Current Consumption and Width

CPU Rack and Expansion Rack current consumption and width can be displayed by selecting Current Consumption and Width from the

Options Menu in the CS1 Table Window. If the capacity of the Power Supply Unit is exceeded, it will be displayed in red characters.
