Unit Current and Power Consumption
Example 2: For C200HW-PA204S
ID212 DC Input Units:
CT002 High-speed Counter Units:
External power supply used (for ID212): 0.8 A
Power Supply
5-V system
26-V system
24-V system
Total = 22.5 W (≤ 30W)

Current Consumption
0.01 x 6 + 0.3 x 2 = 0.66 A (≤ 4.6 A)
0
Ext. power supply = 0.8 A (≤ 0.8 A)
Current Consumption
0.01 x 4 + 0.12 + 0.27 +0.3
= 0.73 A (≤ 4.6 A)
0.075 x 4 = 0.30 A (≤ 0.6 A)
Ext. power supply = 0.8 A (≤ 0.8 A)
The total power consumption (primary power input) for an individual Rack can be
broadly calculated as shown in the following examples.
Example 1: CPU Rack
Total power consumption of Units + 3.5
3.5 = CPU Unit power consumption
0.6 = 60% efficiency
0.55= Power rate
Example 2: All Other Racks
Total power consumption of Units + 2
2 = I/O Power Supply Unit (Remote I/O Slave Unit) power consumption
0.6 = 60% efficiency
0.55 (1) = Power rate
(Number in parentheses: when RT002-P or RT202 is used.)
