Calculating Power Supply Loading; Load Requirements For Hardware Components - GE 90-30 PLC Series Installation And Hardware Manual

Calculating Power Supply Loading

The load placed on a power supply in a Series 90-30 PLC baseplate is the sum of the internal and
external loads placed on it by all of the hardware components in the baseplate (backplane, modules,
etc.), as well as external loads connected to the Isolated + 24 VDC supply. Use of the Isolated +24
Volt power supply output is optional; however, this output can be used to drive a limited number
of input devices. The maximum total power output rating of the Power Supplies is 30 watts;
however, the individual +5VDC outputs can be rated for either 15 or 30 Watts, depending on the
Power Supply catalog number. See Table 12-1, "Power Supply Feature Comparison Table," for
details.

Load Requirements for Hardware Components

The following table shows the DC load required by each module and hardware component. All
ratings are in milliamps (except where noted). Input and Output module current ratings are with all
inputs or outputs on. Three voltages are listed in the table:
Note that the figures listed in the following table are maximum (worst case) requirements , not
typical requirements.

+5 VDC provides primary power to operate most internal circuits
+24 VDC Relay Power provides power for circuits that drive the relays on Relay modules
+24 VDC Isolated provides power to operate a number of input circuits (input modules only),
and any external circuits connected to the 24 VDC Output terminals on the power supply
terminal strip.
