Formula:
DC-powered CP1L power consumption = 5-V current consumption × 5 V/
70% (CP1L internal power efficiency) + 24-V current consumption × 1.1
(current fluctuation factor)
Calculation Example
CPU Unit
CP1L-M40DR-D
0.220 A
0.080 A
CP1L Power Consumption
= (0.39 A × 5 V/70% + 0.139 A × 24 V) × 1.1
= 6.73 W
The above calculation results show that a power supply with a capacity of
7 W or greater is required.

Note (1) The current consumption of the CP1W-ME05M Memory Cassette and
CP1W-CIF01/11 Option Boards are included in the current consumption
of the CPU Unit.
(2) CPU Units with DC power do not provide an external power supply.
(3) The current consumptions given in the following table must be added to
the current consumption of the CPU Unit if an Expansion Unit or Expan-
sion I/O Unit is connected.
(4) The external power supply cannot be used if an Expansion Unit or Expan-
sion I/O Unit is connected to a CPU Unit with 14 or 20 I/O points.
