Power Consumption of an Entire Station

The power consumption of a complete station consists of the sum of all individual consumptions.

• Consumers over terminals L+ and M on the AC500 Terminal Base/AC500-eCo CPU:
  • CPU itself
  • I/O modules attached on the I/O-Bus
  • Communication modules attached (AC500 Terminal Base)
• 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:
  • Digital I/O modules
  • Analog 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.

• Dimensioning of the Fuses
