Power Supply Unit Section 3-2
Unit Limits for Expansion
I/O Blocks
The current consumption limits for the CPU Block and Expansion I/O Block
are given in the following table. Be sure that current consumption of the con-
nected Units does not exceed the following limits.
Note 1. The CPU Block current consumption includes the CPU Unit, Communica-
tions Unit, Inner Boards, and I/O Control Unit.
2. The Expansion I/O Block current consumption includes I/O Interface Unit.
3. An Analog Power Supply Unit must be counted as a Unit, just like I/O or
Dedicated I/O Units.
4. The maximum current consumption will be 3.6 A if the CQM1-PA203 Pow-
er Supply Unit is used.
