Overall Information (valid for complete AC500 Product Family) > Power Consumption of an Entire Station
● 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.

Example In the example, the AC500 control system consists of the following devices:
● CPU PM5xx-ETH
● 4 communication modules
● 7 I/O modules (digital and analog)
● As well as the required terminal bases and terminal units
