(2) This is the rated value for the maximum system configuration. Use the fol-
lowing formula to calculate DC power consumption for CPU Units with DC
power.
Formula:
DC-powered CP1L-EL/EM power consumption = (5 V current consump-
tion × 5 V/70% (CP1L-EL/EM internal power efficiency) + 24 V current
consumption × 24 V) × 1.1 (current fluctuation factor)
Calculation Example
CPU Unit
1st Unit
CP1L-EM40DR-D CP1W-20EDT
0.320 A 0.130 A
0.080 A 0.000 A
CP1L-EL/EM Power Consumption
= (0.57 A × 5 V/70% + 0.263 A × 24 V) × 1.1
= 11.42 W
The above calculation results show that a power supply with a capacity of
12 W or greater is required.
(3) General specification of Expansion I/O Units and Expansion Units will be
the same criteria with CPU Units.
