Power and Compatibility

SIMATIC 545/555/575 System Manual
B.1 Power Consumption
Table B-1 shows the power consumption of 545 and 555 CPUs, with and
without PROFIBUS-DP annex cards. Table B-2 shows the power
consumption of 575 CPUs, with or without an annex card. (The Series 505
remote I/O and PROFIBUS-DP I/O annex cards have the same effect on
power consumption.)

All current Series 505 power supply modules can supply up to 55 watts of
power to the modules listed in Table B-3.
You can increase the available power by using two power supplies in the
5056511 Redundant Base for a total of 90 watts if the redundant mode is
not required. In this case, if one power supply module fails, the other power
supply module trips off as well when the actual load is above its 55 watt
capacity.
