Remove Power
WARNING: When you insert or remove the module while backplane 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.
Repeated electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that can
affect module operation.
System Assembly
The module can be attached to the controller or an adjacent I/O module before or after
mounting. For mounting instructions, see Panel Mounting on page 8, or DIN Rail Mounting on
page 9. To work with a system that is already mounted, see Replacing a Single Module within a
System on page 9.
The following procedure shows you how to assemble the Compact I/O system.

1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked (fully right)
position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together (or
to a controller).
4. Move the module back along the tongue-and-groove slots until the bus connectors (2)
line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3).
Use your fingers or a small screwdriver.
6. To allow communication between the controller and module, move the bus lever fully to
the left (4) until it clicks.
Be sure it is locked firmly in place.
ATTENTION: When attaching I/O modules, it is very important that the bus
connectors are securely locked together to ensure proper electrical connection.
7. Attach an end cap terminator (5) to the last module in the system by using the
tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
IMPORTANT
A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end
of the communication bus.
Mounting Expansion I/O
ATTENTION: During panel or DIN rail mounting of all devices, be sure that all
debris (such as metal chips or wire strands) is kept from falling into the module.
Debris that falls into the module could cause damage on power up.
ATTENTION: When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring method
that complies with the governing electrical codes.

CompactLogix Isolated Analog Input Module
Grounding the Module
ATTENTION: This product is intended to be mounted to a well-grounded mounting
surface such as a metal panel. Additional grounding connections from the power
supply's mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding
Guidelines, Rockwell Automation publication 1770-4.1, for additional information.
Minimum Spacing
Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow 50 mm (2 in.)
of space on all sides for adequate ventilation, as shown.
Panel Mounting
Mount the module to a panel by using two screws per module. Use M4 or #8 panhead screws.
Mounting screws are required on every module.
Panel Mounting Using the Dimensional Template
NOTE: Overall hole spacing
tolerance: ±0.4 mm (0.016 in.).
Locate holes every 17.5 mm (0.689 in.) to allow for a
mix of single-wide and one-and-a-half-wide modules
(for example, the 1769-OA16 module).
Host Controller
Spacing for single-wide modules 35 mm (1.378 in.).
l Mounting
Spacing for one-and-a-half-wide
modules 52.5 mm (2.067 in.).
Refer to host controller documentation for this dimension.
Panel Mounting Procedure Using Modules as a Template
The following procedure allows you to use the assembled modules as a template for drilling holes
in the panel. If you have sophisticated panel mounting equipment, you can use the dimensional
template provided on page 8. Due to module mounting hole tolerance, it is important to follow
this procedure.
1. On a clean work surface, assemble no more than three modules.
2. Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.
3. Return the assembled modules to the clean work surface, including any previously
mounted modules.
Publication 1769-IN074C-EN-P - March 2011

4. Drill and tap the mounting holes for the recommended M4 or #8 screw.
5. Place the modules back on the panel and check for proper hole alignment.
6. Attach the modules to the panel using the mounting screws.
TIP
If mounting more modules, mount only the last one of this group and put the others
aside. This reduces remounting time during drilling and tapping of the next group.
7. Repeat steps 1… 6 for any remaining modules.
DIN Rail Mounting
The module can be mounted using the following DIN rails:
35 x 7.5 mm (1.38 x 0.30 in.; EN 50 022 - 35 x 7.5)
35 x 15 mm (1.38 x 0.59 in.; EN 50 022 - 35 x 15)
Before mounting the module on a DIN rail, close the DIN rail latches. Press the DIN rail
mounting area of the module against the DIN rail. The latches will momentarily open and lock
into place.
Replacing a Single Module within a System
The module can be replaced while the system is mounted to a panel (or DIN rail). Follow these
steps.
1. Remove power.
See important note on page 6.
2. On the module to be removed, remove the upper and lower mounting screws from the
module (or open the DIN latches by using a flat-blade or phillips-style screwdriver).
3. Move the bus lever to the right to disconnect (unlock) the bus.
4. On the right-side adjacent module, move its bus lever to the right (unlock) to disconnect
it from the module to be removed.
5. Gently slide the disconnected module forward.
If you feel excessive resistance, check that the module has been disconnected from the
bus and that both mounting screws have been removed (or DIN latches opened).
TIP
It may be necessary to rock the module slightly from front to back to remove it, or,
in a panel-mounted system, to loosen the screws of adjacent modules.
6. Before installing the replacement module, be sure that the bus lever on the module to be
installed and on the right-side adjacent module are in the unlocked (fully right) position.

System Wiring Guidelines
ATTENTION: Use supply wires suitable for 20 °C (68 °F) above surrounding
ambient.
Consider the following when wiring your system:
•
•
•
•
Do not use the analog module’s NC terminals as connection points.
Channels are 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 module end. Keep the
shield connection to ground as short as possible.(1)
• To ensure optimum accuracy, limit overall cable impedance by keeping your cable as
short as possible. Locate the I/O system as close to your sensors or actuators as your
application will permit.
• If multiple power supplies are used with analog inputs, the power supply commons must
be connected.
• The 1769-IF4I module 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.
(1)
In environments where high-frequency noise may be present, it may be necessary to directly ground cable shields to earth
at the module end and via a 0.1µF capacitor at the sensor end.
Publication 1769-IN074C-EN-P - March 2011
CompactLogix Isolated Analog Input Module
11
• Voltages on Ch+, Ch-, and Ch_iRtn for a single, isolated channel of the 1769-IF4I
module must not exceed the maximum overload levels detailed in the
Input Specifications on page 21.
ATTENTION: To comply with UL restrictions, this equipment must be powered
from a source compliant with Class 2 or Limited Voltage/Current.
Be careful when stripping wires. Wire fragments that fall into a module could
cause damage at power up. Once wiring is complete, make sure that the module
is free of all metal fragments.
Wiring Differential Inputs
Belden 8761 Cable
(or Equivalent)
Analog Source
IMPORTANT
1769-IF4I input channels connected to current sources must have a jumper wire
placed between Ch#_iRtn and the Ch#- terminals for that channel.

Removing the Finger-safe Terminal Block
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.
Be sure that power is removed or the area is nonhazardous before proceeding.
When wiring field devices to the module, it is not necessary to remove the terminal block. If you
remove the terminal block, use the write-on label on the side of the terminal block to identify the
module slot location and type. RTB position can be indicated by circling either the ‘R’ for right
side or ‘L’ for left side.
To remove the terminal block, loosen the upper and lower retaining screws. The terminal block
will back away from the module as you remove the screws. When replacing the terminal block,
torque the retaining screws to 0.46 N•m (4.1 lb•in).
Wiring the Finger-safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Loosen the terminal screws to be wired.
2. Route the wire under the terminal pressure plate.
Publication 1769-IN074C-EN-P - March 2011
14
CompactLogix Isolated Analog Input Module
You can use the bare wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.)
spade lug.
The terminal screws are non-captive. Therefore, it is possible to use a ring lug
[maximum 1/4 inch o.d. with a 0.139 in. minimum i.d. (M3.5)] with the module.
TIP
3. Tighten the terminal screw, making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 N•m (6 lb•in).
If you need to remove the finger-safe cover, insert a screwdriver into one of the
square wiring holes and gently pry off the cover. If you wire the terminal block
with the finger-safe cover removed, you will not be able to put the cover back
on the terminal block because the wires will obstruct the cover.

Configuration Data File
The manipulation of the bits from this file is normally done with programming software (for
example, RSLogix 5000 or RSNetWorx for DeviceNet software) during initial configuration of
the system. In that case, graphical screens are provided by the programmer to simplify
configuration. However, some systems, like the 1769-ADN DeviceNet adapter, also allow the
bits to be altered as part of the control program, using communication rungs. In that case, it is
necessary to understand the bit arrangement.

The over- or under-range flag will come on when the normal operating range (over/under) is exceeded. The module will
continue to convert the analog input up to the maximum full scale range. The flag automatically resets when within the
normal operating range.
Resolution is dependent upon your filter selection. The maximum resolution is achieved with the 10 Hz filter selected.
Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the input
signal and the value that floats above ground potential (for example, 10V DC input signal and 20V DC potential above
ground).
Includes offset, gain, non-linearity and repeatability error terms.
