Publication 1769-IN032A-EN-P - April 2003

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

Remove Power

(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.

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.

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.

Compact 32-point 24V dc Sink/Source Input Module 5

Publication 1769-IN032A-EN-P - April 2003

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 6, or DIN

Rail Mounting on page 8. To work with a system that is already mounted, see

Replacing a Single Module within a System on page 8.

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 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.

the tongue-and-groove slots as before.

8. Lock the end cap bus terminator (6).

Mounting Expansion I/O

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:

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.

IMPORTANT

A 1769-ECR or 1769-ECL right or left end cap must be used to

terminate the end of the serial communication bus.

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.

Panel Mounting Using the Dimensional Template

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

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.

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.

Host Controller

Note: Overall hole spacing

tolerance: ±0.4mm (0.016 in.).

8 Compact 32-point 24V dc Sink/Source Input Module

Publication 1769-IN032A-EN-P - April 2003

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.

Compact 32-point 24V dc Sink/Source Input Module 9

Publication 1769-IN032A-EN-P - April 2003

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).

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.

Input Wiring

Basic wiring of input devices

(1)

to the 1769-IQ32 is shown below.

ATTENTION

– Miswiring of the module to an AC power source will damage

the module.

– 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.

Sinking/Sourcing Inputs - Sourcing/sinking describes the current flow between the I/O module and the field device.

Sourcing I/O circuits supply (source) current to sinking field devices. Sinking I/O circuits are driven by a current sourcing

field device. Field devices connected to the negative side (DC Common) of the field power supply are sinking field devices.

Field devices connected to the positive side (+V) of the field supply are sourcing field devices. Europe: DC sinking input and

sourcing output module circuits are the commonly used options.

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

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.
