Note
(1) The above values are for a cold start at room temperature for an AC pow-
er supply, and for a cold start for a DC power supply.
• A thermistor (with low-temperature current suppression characteris-
tics) is used in the inrush current control circuitry for the AC power sup-
ply. The thermistor will not be sufficiently cooled if the ambient
temperature is high or if a hot start is performed when the power sup-
ply has been OFF for only a short time, so in those cases the inrush
current values may be higher (as much as two times higher) than those
shown above.
• A capacitor delay circuit is used in the inrush current control circuitry
for the DC power supply. The capacitor will not be charged if a hot start
is performed when the power supply has been OFF for only a short
time, so in those cases the inrush current values may be higher (as
much as two times higher) than those shown above.
Always allow for this when selecting fuses and breakers for external cir-
cuits.
(2) Use the external power supply to power input devices. Do not use it to
drive output devices.
(3) 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 power consumption = 5-V current consumption
×
5 V/
70% (CP1L internal power efficiency) + 24-V current consumption
×
1.1
(current fluctuation factor)
Calculation Example
CP1L Power Consumption
= (0.47 A
×
5 V/70% + 0.263 A
×
24 V)
×
1.1
= 10.64 W
The above calculation results show that a power supply with a capacity of
7 W or greater is required.
