* Refer to module specifications in GFK-0898, Series 90-30 I/O Module Specifications Manual for more details.
** Note that the model 350-364 CPUs do not support the A version (IC690ACC901A) of the Miniconverter.

Power Supply Loading Calculation Examples

Following are examples of calculations for determining the total load placed on a Series 90-30 PLC
power supply by the Series 90-30 PLC hardware. All current figures are expressed in milliamps.
Note that although each output is rated at 15 or 20 watts (with the exception that the +5 VDC
output for the High Capacity power supply is rated at 30 watts), the total combined output can be
no more than 30 watts. The power required by external circuits connected to the 24 VDC
OUTPUT terminals on the power supply terminal strip should be added to the calculation.
