Verify Compatibility
This table shows the compatible pairs of RSLogix 5000 software versions and controller
firmware revisions.
Before You Begin
This section contains information you should understand before installing the CompactLogix
packaged controller.
Restrictions
The maximum amount of expansion modules that can be used with the packaged controllers is
two. Within that limit, the number of expansion I/O modules that can be attached to the
packaged controller depends on the bus current draw of the modules being attached.
Each packaged controller has a specified amount of available bus current as shown in this table.
To determine the number of expansion I/O modules you can add, total the bus current draw
(maximum) of your planned expansion I/O modules and the end cap. If your result is less than

The series B controllers are compatible only with the controller firmware and the RSLogix 5000
software versions as indicated in the table below.
Attempting to use controllers with incompatible software and firmware revisions can result in

Panel Mount the System
To mount your system to a panel, complete these steps.
1. Using the assembled system as a template, carefully mark the center of all mounting holes
on the panel.
2. Remove the system and drill and tap the mounting holes for the recommended M4 or #8
screws.
3. Place the grounding panel (if used) and CompactLogix system on the panel to check for
proper hole alignment.
4. Insert the recommended screws into the mounting tabs on the packaged controller and
expansion modules (if used) and tighten.
DIN-rail Mount the System
To mount your system on a DIN rail, complete these steps.
The packaged controller can be mounted on these DIN rails:
•EN 50 022 - 35 x 7.5 mm (1.38 x 0.30 in.)
•EN 50 022 - 35 x 15 mm (1.38 x 0.59 in.)
ATTENTION: When this product is grounded through the DIN rail to chassis ground, use
zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail
materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can
result in improper or intermittent grounding. Secure DIN rail to mounting surface approximately
every 200 mm (7.8 in.) and use end-anchors appropriately.

CompactLogix Controller 15
Rockwell Automation Publication 1769-IN082C-EN-P - February 2013
1. Before mounting the packaged controller on a DIN rail, close the DIN-rail latches.
2. Press the DIN-rail mounting area of the packaged controller against the DIN rail.
The latches momentarily open and lock into place on the DIN rail.
3. Press the DIN rail mounting area of the packaged controller against the DIN rail.
The latches momentarily open and lock into place on the DIN rail.
Grounding Considerations
This product is intended to be mounted to a well-grounded mounting surface such as a metal
panel. Additional grounding connections from the packaged controller’s mounting tabs or DIN
rail (if used) are not required unless the mounting surface cannot be grounded.
Refer to the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1,
for additional information.
Wiring Power to the System
Use this diagram as a reference when wiring the required 24V DC power to your system.
WARNING:
•Do not connect directly to line voltage. Line voltage must be supplied by a suitable, approved
isolating transformer or power supply having short-circuit capacity not exceeding 100VA
maximum or equivalent.
•Explosion hazard, do not remove or replace fuses on the packaged controller unless power has
been disconnected or the area is known to be free of lb. concentrations of flammable gases or
vapors.
For more information about replacing the fuse, see the Fuse Replacement Procedure in the
Compact Expansion Power Supplies Installation Instructions, publication 1769-IN028.

Wire the I/O Removable Terminal Blocks
To begin wiring your embedded I/O removable terminal blocks, loosen the screws at the top and
bottom of the removable terminal block and remove the removable terminal block from the
packaged controller.
WARNING:
•When you connect or disconnect the Removable Terminal Block (RTB) with field side power
applied, an electrical arc can occur. This could cause an explosion in hazardous location
installations.
•If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
ATTENTION:
•Mis-wiring the removable terminal blocks to an AC power source causes damage to the
packaged controller.
•Be careful when stripping wires. Wire fragments that fall into an removable terminal block
could cause damage at power up. Once wiring is complete, ensure the removable terminal
blocks are free of all metal fragments.
•When wiring I/O removable terminal blocks, tighten terminal screws with care. Excessive
tightening can strip a screw.

Analog I/O Wiring Diagrams
•All analog I/O commons (ANLG COM) are connected in the analog I/O card of the
packaged controller. The analog common (ANLG COM) is not connected to earth
ground inside the packaged controller.
•Analog I/O channels are not isolated from each other.
•Use Belden 8761 (or equivalent) shielded wire.
•Under normal conditions, the drain wire and shield junction must be connected to earth
ground via a panel or DIN rail mounting screw at the analog I/O removable terminal
block end. Keep the shield connection to ground as short as possible.
•To ensure optimum accuracy, limit overall cable impedance by keeping your cable as
short as possible. Plan to place the packaged controller as close to your sensors or
actuators as your application permits.(1)
•If multiple power supplies are used with analog inputs:
•the power supply commons must be connected.
•do not exceed the specified isolation voltage.
•The embedded analog I/O does not provide loop power for analog inputs. Use a power
supply that matches the input transmitter specifications.
•Differential analog inputs are more immune to noise than single-ended analog inputs.
•Voltage outputs (Vout 0+ and Vout 1+) of the analog I/O are referenced to ANLG
COM. Load resistance for a voltage output channel must be equal to or greater than 1
K.
•Current outputs (Iout 0+ and Iout 1+) of the analog I/O source current that returns to
ANLG COM. Load resistance for a current output channel must remain between
0…300 .
•Voltages on Vin+, V/Iin-, and Iin+ of the analog I/O must be within 0 to +10V DC of
analog common.
ATTENTION: Analog outputs may fluctuate for less than a second when power is applied or
removed. This characteristic is common to most analog outputs. While the majority of loads will
not recognize the short signal, take preventive measures to ensure that connected equipment is
not affected.
IMPORTANT
In environments where high-frequency noise may be present, it may be necessary to directly
ground cable shields to earth at the removable terminal block end and via a 0.1μF capacitor at
the sensor end.
(1) Cable length over 50 m (164.04 ft) may impact accuracy. For details, refer to the Compact Combination Analog I/O Module, publication
1769-UM008.
