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
(1)
) and to circuits not exceeding
Over Voltage Category II
(2)
(IEC 60664-1).
(3)
Prevent Electrostatic Discharge
ATTENTION
!
Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. 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
ATTENTION
!
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.

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 screw driver.
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 serial 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.
Minimum Spacing
Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown:
Side
Controller
Top
Bottom
Side
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.
Publication 1769-IN032A-EN-P - April 2003
Compact 32-point 24V dc Sink/Source Input Module 7
Panel Mounting Using the Dimensional Template
Spacing for single-wide modules 35mm (1.378 in.)
Spacing for one-and-a half-wide modules 52.5mm (2.067 in.)
Refer to host controller documentation for this dimension.
Note: Overall hole spacing tolerance:
±0.4mm (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 (e.g., 1769-OA16).
Panel Mounting Procedure Using Modules as a Template
30535-M
This procedure lets you 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 7. Due to module 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.
Publication 1769-IN032A-EN-P - April 2003
8 Compact 32-point 24V dc Sink/Source Input Module
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.
7. Repeat steps 1 to 6 for any remaining modules.
DIN Rail Mounting
The module can be mounted using these 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).
1. Remove power. See important note on page 4.
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 screw driver).
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: 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.
7. Slide the replacement module into the open slot.

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 lcation 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).
Wiring the Finger-safe Terminal Block
upper retaining wiring the finger-safe terminal lower retaining
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 [max. 1/4” o.d. with a 0.139” 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.
