Install the 1769-OG16 Module

Attach the module to the controller or an adjacent I/O module before or after mounting. For mounting instructions, see Mount Module to Panel Using the Dimensional Template, or Mount Module to DIN Rail. To work with a system that is already mounted, see Replace a Single Module Within a System.

The following procedure shows you how to assemble the Compact I/O system.

30536-M

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. Use your fingers or a small screwdriver to push the bus lever back slightly to

clear the positioning tab (3).

Publication 1769-IN078A-EN-P - May 2006

Compact TTL Output Module 7

6. To allow communication between the controller and module, move the bus

lever fully to the left (4) until it clicks, making sure it is locked firmly in place.

ATTENTION

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

When attaching I/O modules, it is very important that the bus connectors are securely locked together to be sure of proper electrical connection.

You must use a 1769-ECR or 1769-ECL right or left end cap to terminate the end of the serial communication bus.

Replace 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.

Refer to Remove Power on page 3.

2. 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 is disconnected from the bus and that both mounting screws are 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.

Publication 1769-IN078A-EN-P - May 2006

8 Compact TTL Output Module

6. Be sure that the bus lever on the module and on the right-side adjacent

module are in the unlocked (fully right) position before installing the replacement module.

7. Slide the replacement module into the open slot.

8. Connect the modules 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).

Mount Expansion I/O

ATTENTION

During panel or DIN rail mounting of all devices, be sure that all debris, including metal chips or wire strands, is kept from falling into the module. Debris that falls into the module could cause damage when cycling power.

Minimum Spacing

Maintain spacing from enclosure walls, wireways, or adjacent equipment. Allow 50 mm (2 in.) of space on all sides for adequate ventilation, as shown.

Mount Module to Panel 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.

Host Controller

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 (for example, the 1769-OA16 module).

Mount Module to Panel Procedure Using Modules as a Template

This procedure lets you use the assembled modules as a template for drilling holes in the panel. Due to module-mounting hole tolerance, it is important to follow this procedure.

Refer to Mount Module to Panel Using the Dimensional Template on page 9 if you have sophisticated panel-mounting equipment.

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 screws.

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

7. Repeat steps 1 to 6 for any remaining modules.

If mounting more modules, mount only the last one of this group and put the others aside. This reduces the remounting time during drilling and tapping of the next group.

Publication 1769-IN078A-EN-P - May 2006

10 Compact TTL Output Module

Mount Module to DIN Rail

The module can be mounted using these DIN rails.

• 35 x 7.5 mm (EN 50 022 - 35 x 7.5)

• 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.

12 Compact TTL Output Module

Ground the 1769-OG16 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.

A removable, write-on label is provided with the module. Remove the label from the door, mark the identification of each terminal with permanent ink, and slide the label back into the door. Your markings (ID tag) will be visible when the module door is closed.

Ground the Module

Upper Retaining Screw

Lower Retaining Screw

Wire the finger-safe terminal block.

Remove the Finger-safe Terminal Block

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-IN078A-EN-P - May 2006

Compact TTL Output Module 13

Wire 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.

TIP

The terminal screws are non-captive. Therefore, it is possible to use a ring lug [max 1/4 in. 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 Nm (6 in-lb).

TIP

If you need to remove the finger-safe cover, insert a screwdriver 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.

Configure the 1769-OG16 Module

The following I/O memory mapping lets you configure the 1769-OG16 module.

Output Data File

For each module, slot x, word 0 in the output data file contains the state of the module’s output points. The module implements inverted logic on the TTL outputs. An Output Data File bit set to 1 results in a logic low output voltage on the corresponding output point. An Output Data File bit cleared to 0 results in a logic

high output voltage on the corresponding output point.

14 Compact TTL Output Module

Input Data File

For each module, slot x, word 0 in the input data file contains the state of the module’s output data file (output data echo). During normal operation, these input bits represent the logic state that the outputs are directed to by the control program. They are also dependent upon the:

• Program mode configuration (if supported by the controller).

• Fault mode configuration (if supported by the controller).

The module implements inverted logic on the TTL outputs. An Output Data File bit set to 1 directs a logic low output voltage on the corresponding output point. An Output Data File bit cleared to 0 directs a logic high output voltage on the

corresponding output point.

IMPORTANT

The output module’s input data file reflects the output data echo of the module, not necessarily the electrical state of the output terminals. It does not reflect shorted or open outputs.

It is important to use this input word if the controller adapter supports the Program mode or Fault mode function, and if it is configured to use them.

Publication 1769-IN078A-EN-P - May 2006

Compact TTL Output Module 15

Configuration File

The read/writable configuration data file allows the setup of the hold last state and user-defined safe state conditions.

The manipulation of the bits from this file is normally done with programming software (such as RSLogix 500 or RSNetworx for DeviceNet) during initial configuration of the system. In that case, graphical dialogs are provided via the programmer to simplify configuration. However, some systems (for example, 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.
