1 / 10 page B-108 CJ1 SYSTEM POWER AND EXP ANSION Power and Expansion Selection This section provides tools to calculate the CJ1 system current consumption total needed to select the power supply. When the number of modules or power requirements exceeds the capability of the power supplies available, I/O expansion racks solve the problem. If the number of modules per rack exceeds 10 or the current consumption is greater than the capacity of the power supply units, use the CPU and expansion rack configuration. A CJ1 system consists of a power supply, a CPU, and up to 10 basic I/O, special I/O and CPU bus units, and an end cover. See page B-109. What is the basic configuration? The expansion I/O rack contains a power supply, an I/O interface module and the remaining I/O modules. Each expansion rack requires a power supply, the I/O interface module and up to 10 more modules. Note: Order one CJ1W-IC101 I/O control module for the CPU rack and one CJ1W-II101 I/O interface module for each I/O expansion rack. Connect the modules with a cable of the appropriate length. Second and third I/O expansion racks connect between I/O interface modules. See page B-117 for details. What goes on expansion I/O racks? All the current consumption ratings for the CPU, basic I/O, special I/O and CPU bus units are collected in the tables on pages B-110 to B-111. Where are ratings to calculate overall current consumption? Compare the current consumption total of basic I/O, special I/O, and CPU bus units to determine which power supply to use. Note: If more than 10 modules are required or the current consumption exceeds the output capacity of the power supplies, go to page B-109 for configuration of I/O expansion racks. The same power supply units can be used for both CPU and I/O expansion racks. Depending on the CPU chosen, the system can be expanded with up to three additional racks of basic I/O, special I/O and CPU bus units. Which power supply is right? How many expansion I/O racks can be used? Output rating Output capacity Power supply model See page 5 A, 5 VDC 25 W max. CJ1W-PD025 B-110 5 A, 5 VDC with 2 A RUN output 25 W max.
