*Limit 10 Analog Output modules per I/O rack.
** Limit 4 PFQ modules per I/O rack.
*** Limit 2 16-pt. modules per rack. Limit 5 8-pt. modules per rack with
internal power supply. Use 0 mA for 24V value when using an external
24V supply.
Total mA @ 5V = ( )
Total mA @ 24V= ( )
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 5V total by 5.1. ( )
5. Multiply 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
If the answer to 8 is Yes, use power supply 900P02-0001
If the answer to 8 is No, use power supply 900P01-0001
