The
total power consumption for each Rack can be obtained from the following
formulas:
Total power consumption for each Unit + 7 (8)
0.6 x 0.55 (1)
CPU Rack =
(VA)
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
0.6 x 0.55 (1)
All other Racks =
(VA)
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 PS21
1, R
T002-P or
R
T202
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.
Voltage Current consumption Power consumption
5 V
(1) 0.01 x 7 + 0.25 = 0.32 A (≤ 1.6 A)
(1) x 5 V = 1.6 W
26 V
(2) 0.075 x 4 = 0.30 A (≤ 0.6 A)
(2) x 26 V = 7.8 W
24 V
(3) 0.06 x 3 + 0.3 = 0.48 A (≤ 0.8 A)
(3) x 24 V = 11.52 W
Total ---
20.92 W (≤ 23 W)
Assume
that six DC Input Units and two High-speed Counter
Units are mounted
to
a Rack, along with the PS221 Power Supply
. The following table shows
how
the total power consumption is calculated.
Voltage Current consumption Power consumption
5 V
(1) 0.01 x 6 + 0.3 x 2 = 0.66 A (≤ 2.7 A)
(1) x 5 V = 3.3 W
26 V (2) 0 (2) 0
24 V
(3) Service power supply = 0.8 A (≤ 0.8A)
(3) x 24 V = 19.2 W
Total ---
22.5 W (≤ 28 W)
Assume that the following Units are mounted to a Rack to which a C200H-
CPU11-E
is mounted. The following table shows how the total power consump
-
tion is calculated.
Voltage Current consumption Power consumption
5 V
(1) 0.01 x 6 + 0.18 = 0.24 A (≤ 1.1 A)
(1) x 5 V = 1.2 W
26 V
(2) 0.075 x 4 = 0.30 A(≤0.6 A)
(2) x 26V = 7.8 W
24 V
(3) 0.06 x 2 + 0.3 = 0.42 A(≤0.8 A)
(3) x 24 V = 10.08 W
Total ---
19.08 W (≤ 20.5 W)
