Publication
1769-IN020D-EN-P - October 2008
Before You Begin
Consider the following when planning your CompactLogix system:
• The CompactLogix controller is always the leftmost module in the
system.
• The controller must be within four modules of the system power
supply. Some I/O modules may be up to eight modules away from the
power supply. See the documentation for your 1769 I/O modules for
details.
• The 1769-L32E controller supports as many as 16 I/O modules and
the 1769-L35E controller supports as many as 30 I/O modules. Both
controllers can use a maximum of 3 I/O banks with 2 expansion
cables.
• Each I/O bank requires its own power supply.
• Only one controller can be used in a CompactLogix system.
• A 1769-ECR right end cap or 1769-ECL left end cap is required to
terminate the end of the communication bus.
