The total power consumption for each Rack can be obtained from the following
formulas:
Total power consumption for each Unit + 7 (8)
CPU Rack =
7 = CPU power consumption, (8) = Power consumption of the CPU11-E
0.6 = 60% efficiency
0.55 (1) = Power rate (Number in parentheses: when CPU03-E is used.)
Total power consumption for each Unit + 2
All other Racks =
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 PS211, RT002-P or RT202
is used.)
Assume that four Contact Output Units, three No-Voltage Contact Input Units,
and one Host Link Unit are mounted to a Rack, along with CPU01-E. The follow-
ing table shows how the total power consumption is calculated.
