2.4.5 Power consumption of an entire station

The power consumption of a complete station consists of the sum of all individual consump-
tions.
● Consumers over terminals L+ and M on the AC500 terminal base/AC500-eCo CPU:
–
–
–
● Consumers over the process supply voltage terminals ZP and UP of the AC500 terminal
units / the L+/M or UP/ZP terminals of the AC500-eCo I/O modules:
–
–
The two supply voltages can be provided by the same power supply unit. The CPU and the
I/O modules should, however, be fused separately. Of course also separate power supplies are
possible.
2.4.5.1 Calculation of the total current consumption
Example In the example, the AC500 control system consists of the following devices:
● AC500 CPU with Ethernet interface
● 4 communication modules
● 7 I/O modules (digital and analog)
● As well as the required terminal bases and terminal units
