Add and Configure Standard I/O Modules Chapter 6
Physical Placement of I/O Modules
Depending on the controller catalog number, Compact GuardLogix 5370
controllers support between 8 and 30 I/O modules. For more information on
catalog numbers, see Local Expansion Modules
on page 83.
Consider these factors when determining the physical placement of I/O
modules:
• You can install I/O modules in local and extra banks.
• You can install I/O modules to the left and right of the power supply.
• When a system requires multiple banks, you can install the additional
banks horizontally or vertically, as shown in Figure 2 on page 28
.
• Each I/O module also has a power supply distance rating and maximum
current draw. Considered jointly, distance ratings and current draw
determine where I/O modules can be placed in a bank and what
configuration of modules can be installed in the bank.
For more information on power supply distance ratings, see Power
Supply Distance Rating on page 93. For more information on system
power consumption, see Calculate System Power Consumption
on
page 89.

:
(1) This number must not exceed the power supply current capacity for the bank.
(2) This number must not exceed the power supply current capacity for this side of the bank.
(3) You can install up to eight modules in additional banks if the power supply distance ratings for the modules validate the system design.
