ControlLogix Controllers
The ControlLogix controller provides a scalable controller solution capable of addressing a large number of I/O points.

The controller can be placed into any slot of a ControlLogix chassis and multiple controllers can be installed in the same chassis.
Multiple controllers in the same chassis communicate with each other over the backplane (just as controllers can communicate
over networks) but operate independently.

ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over I/O links. ControlLogix
controllers can communicate over EtherNet/IP, ControlNet, DeviceNet, DH+, Remote I/O, and RS-232-C (DF1/DH-485 protocol)
networks and many third-party process and device networks. To provide communication for a ControlLogix controller, install
the appropriate communication interface module into the chassis.

1756 ControlLogix Power Supplies Specifications

Power Load and Transformer Sizing

The following graphs show the input power requirements for the power supplies, given the power they are providing to the
modules in the chassis.

Follow these steps to determine the power requirements for your chassis.

1. Calculate the Backplane Power Load by adding the power draw (in Watts) for all of the planned modules.
For module power draws, refer to the module specification tables in the ControlLogix Selection Guide,
publication 1756-SG001.
2. Locate the Backplane Power Load on the graph’s vertical (y) axis and determine the corresponding Real Power
(input-power) rating on the horizontal (x) axis.
The Real Power value is the amount of power consumed by the power supply.
