AC Power Supply Selection for racks with I/O
To determine which I/O rack AC power supply to use (P01 or P02), calculate power requirements below.
ATTENTION
Using inadequate power supply will cause the controller to cycle power on and off.

Complete columns A, D and E above.
1. Is column D total mA @ 5V less than 2000mA? Yes/No
2. Is column E total mA @ 24V less than 900mA? Yes/No
3. If the answers to 1 and 2 are YES, go to 4. If the answer to 1 or 2 is NO, use power supply 900P01-0001.
4. Multiply Total mA @ 5V total by 5.1 ( )
5. Multiply Total mA @ 24V total by 24.5 ( )
6. Sum results of 4 and 5. ( )
7. Divide results of 6 by 1000 ( )
8. Is the result of 7 less than 28? Yes/No
9. If the answer to 8 is Yes, use power supply 900P02-0001
10. If the answer to 8 is No, use power supply 900P01-0001
