Power Consumption of an Entire Station

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

An AC500 CPU cluster has

• a power consumption of the CPU itself over the terminals L+ and M of the Terminal Base. After conversion of the voltage, also the I/O-Bus for the attached I/O modules is supplied then.
• a power consumption over the process supply voltage terminals ZP and UP of the Terminal Units / the L+/M or UP/ZP terminals of the AC500-eCo I/O Modules. Through this the digital and analog outputs are also supplied.

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.
