Compact I/O 1769-IF8 Analog Input Module 3
Module Installation
Compact I/O is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for use
in clean, dry environments (Pollution degree 2
Over Voltage Category II
(2)
(IEC 60664-1).
Prevent Electrostatic Discharge
(1)
) and to circuits not exceeding
(3)
ATTENTION
Remove Power
ATTENTION
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins or the terminal
block. Follow these guidelines when you handle the module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• If available, use a static-safe work station.
• When not in use, keep the module in its static-shield box.
Remove power before removing or inserting this module. When
you remove or insert a module with power applied, an electrical
arc may occur. An electrical arc can cause personal injury or
property damage by:
• sending an erroneous signal to your system’s field devices,
causing unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks. Ensure 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 (metal chips, wire strands, etc.) is kept from falling into the
module. Debris that falls into the module could cause damage on
power up.

6 Compact I/O 1769-IF8 Analog Input Module
Panel Mounting
Mount the module to a panel using two screws per module. Use M4 or #8 panhead
screws. Mounting screws are required on every module.
Panel Mounting Using the Dimensional Template
Spacing for one-and-a-half-wide modules 52.5 mm (2.067 in).
Spacing for single-wide modules 35 mm (1.378 in).
Refer to host controller documentation for this dimension.
NOTE: Overall hole spacing
tolerance: ±0.4 mm (0.016 in.)
l Mounting
Locate holes every 17.5 mm (0.689 in) to allow for a
mix of single-wide and one-and-a-half-wide modules
(e.g., 1769-OA16).
Host Controller
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
mounting hole tolerance, it is important to follow these procedures:
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.
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.
NOTE
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.
page 6. Due to module
7. Repeat steps 1 to 6 for any remaining modules.
Publication 1769-IN067B-EN-P - September 2005
Compact I/O 1769-IF8 Analog Input Module 7
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022
- 35 x 7.5) or 35 x 15 mm (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 in order:
1. Remove power. See important note on page 3.
2. On the module to be removed, remove the upper and lower mounting
screws from the module (or open the DIN latches 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).
NOTE
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.
7. Slide the replacement module into the open slot.
8. Connect the modules together by locking (fully left) the bus levers on the
replacement module and the right-side adjacent module.
9. Replace the mounting screws (or snap the module onto the DIN rail).
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.

Field Wiring Connections
Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface such
as a metal panel. Additional grounding connections from the module’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,
Allen-Bradley publication 1770-4.1, for additional information.
System Wiring Guidelines
Consider the following when wiring your system:
• All module commons (ANLG COM) are connected in the analog module.
The analog common (ANLG COM) is not connected to earth ground inside
the module.
• Do not use the analog module’s NC terminals as connection points.
• 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 module 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. 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.
(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.

• The 1769-IF8 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.
• Voltages on Vin+, V/Iin-, and Iin+ of the 1769-IF8 module must be within
±10V dc of analog common.
ATTENTION
Be careful when stripping wires. Wire fragments that fall into a
module could cause damage at power up. Once wiring is
complete, ensure the module is free of all metal fragments.

Removing the Finger-Safe Terminal Block
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 Nm (4.1 in-lbs).
Publication 1769-IN067B-EN-P - September 2005
12 Compact I/O 1769-IF8 Analog Input Module
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. You can use the bare wire
or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug.
NOTE
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 inch
minimum i.d. (M3.5)] with the module.
3. Tighten the terminal screw making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.68 Nm (6 in-lbs).
NOTE
If you need to remove the finger-safe cover, insert a screw
driver into one of the square wiring holes and gently pry the
cover off. If you wire the terminal block with the finger-safe
cover removed, you will not be able to put it back on the
terminal block because the wires will be in the way.
Wire Size and Terminal Screw Torque
Each terminal accepts up to two wires with the following restrictions:
Wire Type Wire Size Terminal Screw
Torque
Solid Cu-90°C (194°F) #14 to #22 AWG 0.68 Nm (6 in-lbs) 0.46 Nm (4.1 in-lbs)

Configuration Data File
The manipulation of the bits from this file is normally done with programming
software (e.g. RSLogix 500, RSNetworx for DeviceNet, etc.) 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. Refer to the Compact™ Analog I/O User Manual, publication number

Overall Accuracy
(1)
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.
(2)
Resolution is dependent upon your filter selection. The maximum resolution is achieved with the 10 Hz filter selected. For
resolution with other filter selections, refer to the user manual, publication 1769-UM002A-EN-P.
(3)
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).
