Omron CJ1G/H-CPU series - CPU Units

103
Basic System Configuration Section 2-3
2-3-3 CJ-series Expansion Racks
To expand the number of Units in the system, CJ-series Expansion Racks can
be connected to CPU Racks. Up to 10 I/O Units can be mounted to each
Expansion Rack and a total of 3 Expansion Racks can be connected. (Only
one Expansion Rack can be connected to a CJ1M CPU Unit.) The maximum
number of I/O Units that can be connected in one PLC is thus 40 (or 20 for
CJ1M CPU Units).
Note 1. Connect the I/O Control Unit directly to the CPU Unit. Proper operation
may not be possible if it is connected any other location.
2. Connect the I/O Interface Unit directly to the Power Supply Unit. Proper op-
eration may not be possible if it is connected any other location.
3. The total length of CS/CJ-series I/O Connecting cable between all Racks
must be 12 m or less.
