Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines
for the Application, Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell
Automation sales office or online at http://www.rockwellautomation.com/literature/) describes some important differences
between solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the
wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that
each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use
or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and
requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for
actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software
described in this manual.

CompactLogix Power Supplies Specifications
1768 CompactLogix Power
Supplies
The 1768 backplane requires one 1768 power supply. The power supply is a
dual input supply that operates in multiple ranges. The power supply also
offers a 24V dc external power source. The power supply sends 24V dc to the
controller in slot 0.
• The controller converts the 24V dc to 5V dc and 24V dc and distributes
it as needed.
– 5V and 24V power to 1769 I/O modules on the right side of the
controller
– 24V power to 1768 modules on the left side of the controller
Power supply sends 24V DC to the controller.

Motion
1769 I/O
Controller sends
- 5V DC to 1768 modules
- 5V and 24V DC to 1769 I/O modules
The 1768 modules do not have a distance rating to the 1768 power supply. For
the 1769 I/O modules in the 1768 system, the distance rating is from the
controller and not the 1768 power supply.

Each 1769-L3x controller and additional bank of I/O modules requires a 1769
power supply. Place 1769 I/O modules to the left or right of the 1769 power
supply. As many as eight I/O modules can be placed on each side of the power
supply.
1769 Compact I/O Power
Supplies
Each 1769 module also has a power supply distance rating (the number of
modules from the power supply). Each module must be located within its
distance rating. See the specifications for the module to determine its distance
rating.
