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.
Publication 1769-IN074C-EN-P - March 2011
8 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
Spacing for single-wide modules 35 mm (1.378 in.).
l Mounting
Refer to host controller documentation for this dimension.
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).
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
CompactLogix Isolated Analog Input Module 9
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.
Publication 1769-IN074C-EN-P - March 2011

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.
TIP
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.
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).
TIP
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.
