Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls
(Publication SGI-1.1 available from your local Rockwell Automation sales office or online at
http://literature.rockwellautomation.com) describes some important differences between solid state
equipment and hard-wired electromechanical devices. Because of this difference, and also because of
the wide variety of uses for solid state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.
cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,
equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell

Environment and Enclosure
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in
IEC
60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR
with electromagnetic compatibility in residential and other environments due
to conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be mounted within
an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
non-metallic. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of

Prevent Electrostatic Discharge
ATTENTION
ATTENTION
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment.
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in
use.
POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated
yellow-chromate steel DIN rail to assure proper grounding. The use of other
DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize,
or are poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm (7.87 in.) and
use end-anchors appropriately.
To comply with the CE Low Voltage Directive (LVD), all connected I/O must be
powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
About the Module
The 1734-8CFGDLX module is an 8-point 24V DC I/O module with 8
self-configuring points and DeviceLogix capabilities. Each of the I/O points
can be a DC input or output.
The module supports removal and insertion under power, auto-address, and
auto-baud in compliance with the POINTBus backplane.

Before You Begin
See the figures to familiarize yourself with major parts of the module, noting
that the wiring base assembly is one of the following:
• 1734-TB or 1734-TBS POINT I/O two-piece terminal base, which
includes the 1734-RTB removable terminal block and 1734-MB
mounting base
• 1734-TOP or 1734-TOPS POINT I/O one-piece terminal base
The 1734-8CFGDLX module is not compatible with 1734-TB3, 1734-TB3S,
1734-TOP3, and 1734-TOP3S terminal bases.

Install the Mounting Base
Follow these steps to install the mounting base on the DIN rail.
1. Position the mounting base vertically above the installed units, for
example, adapter, power supply, or existing module.
2. Slide the mounting base down so that the interlocking side pieces
engage the adjacent module or adapter.

3. Press firmly to seat the mounting base on the DIN rail until the
mounting base snaps into place.
4. To remove the mounting base from the DIN rail, remove the module,
and use a small bladed screwdriver to rotate the base locking screw to
a vertical position. This releases the locking mechanism. Then lift
straight up to remove.

Install the Module
The module can be installed before, or after base installation. Make sure the
mounting base is correctly keyed before installing the module into the
mounting base. In addition, make sure the mounting base locking screw is
positioned horizontal referenced to the base.

Install the Removable Terminal Block
Read this for information if a removable terminal block (RTB) is supplied
with your wiring base assembly, noting that 1734-TOP and 1734-TOPS bases
do not have an RTB.
To insert the RTB, proceed as follows. Note that if you pull up on the RTB
handle to remove the RTB, you can remove and replace the mounting base as
necessary without removing any of the wiring.
1. Insert the end opposite the handle into the base unit, noting that this
end has a curved section that engages with the wiring base.
2. Rotate the terminal block into the wiring base until it locks itself into
place.
3. If an I/O module is installed, snap the RTB handle into place on the
module.
Remove a Mounting Base
To remove a mounting base, you must first remove any installed module and
the module installed in the base to the right.
1. For a module with a two-piece terminal base, use these steps;
otherwise, use step 2
a. Remove the removable terminal block (RTB), if wired.
b. Unlatch the RTB handle on the I/O module.
c. Pull on the RTB handle to remove the RTB.
.
2. Press on the module lock on the top of the module.
3. Pull on the I/O module to remove from the base.
4. Repeat steps 1, 2, 3, and 4 for the module to the right.
5. Lift straight up to remove.
