• High-density and Mixed I/O Units (MD215): 1
• Current for MD215: 0.3 A
Assume
that the following Units are mounted to a rack to which is mounted
the
C200H-CPU11-E.
The following table shows how the total power consumption
is calculated.
Voltage Current consumption Power consumption
5 V
(1) 0.01 x 5 + 0.3 x 1 = 0.35 A (≤ 0.7 A)
(1) x 5 V = 1.75 W
26 V (2) 0 (2) 0
24 V
(3) Current=0.5 A(≤0.8 A)
(3) x 24 V = 12 W
Total ---
13.75 W (≤ 18.5 W)
• Peripheral Interface Unit (IP006)
• SYSMAC NET Link Units (SNT32): 1
• Central Power Supply Adapter (Current 0): 1
• DC Input Units (ID212): 5
• High-speed Counter Units (CT002): 1
• Current for ID212: 0.5 A
The
total power consumption for each Rack can be obtained from the following
formulas:
• CPU Rack: Total power consumption for each Unit + 7 (8)
0.6 x 0.55 (1)
• Expansion I/O Power Supply/Remote I/O Slave Unit:
0.6 x 0.55 (1)
Total power consumption for each Unit + 2
(VA)
(VA)
Where:
7 = Power consumption of the CPU,
(8) = Power consumption of the CPU11-E,
0.6 = 60% efficiency
, and
0.55 (1) = Power rate (Number in parentheses: when CPU03-E is used.)
Where:
2 = Power consumption of the I/O Power Supply or
Remote I/O Slave Unit,
0.6 = 60% efficiency
, and
0.55 (1) = Power rate (Number in parentheses: when
PS211, RT002-P or RT202 is used.)
