Specifications For External Power Supply Expansion - Omron CP1H-X40D Operation Manual

When using the external power supply for AC-power-supply CPU Units, the following limitations apply:
The external power supply for AC-power-supply CP1H CPU Units manufactured since July 2008 (Model CP1H-
X DR-A) can be used beyond 300mA within the capacity range of the power supply built in the CPU Units.
Please calculate the usable capacity of external power supply according to the following example.
• Calculation example of the capacity limit of external power supply
Example 1
CPU Units
Model
CP1H-XA40DR-A
5V 0.42A
24V 0.07A
Power 5V×0.74A=3.7W
consumption 24V×0.532A=12.768W
Usable capac- 30W (Total of usable power consumption)-16.468W=13.532W
ity of external
13.532W/24V=564A
power supply
Example 2
CPU Units
Model
CP1H-XA40DR-A
5V 0.42A
24V 0.07A
Power 5V×0.42A=2.1W
consumption
24V×0.07A= 1.68W
Usable capac- 30W (Total of usable power consumption)-3.78W=26.22W
ity of external
26.22W/24V=1.09A
power supply
Note: use the external power supply under 1.0A even if the calculation
result exceeds 1.0A
For AC-power-supply CPU Units manufactured before July 2008, the specifications are as written in 2-2-1 Gen-
eral Specifications for CP1H CPU Units.
