@@@@-M3D and up to three CJ-series Expansion Racks can be con-
Racks
nected to all other NSJ Controllers by mounting an NSJ I/O Control
Unit (NSJW-IC101).
Each Expansion Rack requires an CJ-series I/O Interface Unit (CJ1W-
II101) and a Power Supply Unit.
Connectable Units Per Expansion Rack: 10 Units including Basic I/O Units, Special I/O
Units, and CPU Bus Units.
NSJ@-@@@@-G5D: Total per NSJ Controller: 10 Units on each of 3
Expansion Racks = 30 Units total
NSJ@-@@@@-M3D: Total per NSJ Controller: 10 Units on one Expan-
sion Rack = 10 Units total
