The DeviceNet 1732D ArmorBlock™ I/O family consists of
stand-alone 24V dc I/O modules that communicate via the
DeviceNet network. The sealed IP67 housing of these modules
requires no enclosure (Note that environmental requirements other
than IP67 may require an additional appropriate enclosure.) I/O
connectors are sealed M8 (pico) or M12 (micro) styles while the
network and auxiliary power connectors are sealed M12 style.

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://www.ab.com/manuals/gi)
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.

SHOCK HAZARD

Important User Information

Reproduction of the contents of this manual, in whole or in part, without written
permission of Rockwell Automation, Inc. is prohibited.

Throughout this manual we use notes to make you aware of safety considerations.

WARNING

Identifies information about practices or circumstances that
can cause an explosion in a hazardous environment, which
may lead to personal injury or death, property damage, or
economic loss.

ATTENTION

IMPORTANT

ATTENTION

Identifies information about practices or circumstances that
can lead to personal injury or death, property damage, or
economic loss. Attentions help you:

• identify a hazard

• avoid a hazard

• recognize the consequence

Identifies information that is critical for successful application
and understanding of the product.

Labels may be located on or inside the module to alert people
that dangerous voltage may be present.

Environment and Enclosure

This equipment is intended for use in overvoltage Category II
applications (as defined in IEC publication 60664-1), at altitudes
up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial
equipment according to IEC/CISPR Publication 11. Without
appropriate precautions, there may be potential difficulties
ensuring electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.

This equipment is supplied as "enclosed" equipment. It should
not require additional system enclosure when used in locations
consistent with the enclosure type ratings stated in the
Specifications section of this publication. Subsequent sections of
this publication may contain additional information regarding
specific enclosure type ratings, beyond what this product
provides, that are required to comply with certain product safety
certifications.

NOTE: See NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure. Also, see the
appropriate sections in this publication, as well as the
Allen-Bradley publication 1770-4.1 ("Industrial Automation
Wiring and Grounding Guidelines"), for additional installation
requirements pertaining to this equipment.

Install Your ArmorBlock I/O Module

ATTENTION

To install the module:

• Set the node address

• Mount the module

• Connect the cord sets

• Attach the network cables

• Communicate with the module

Preventing Electrostatic Discharge

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.

• If available, use a static-safe workstation.

• When not in use, store the equipment in

appropriate static-safe packaging.

Set the Node Address

Valid node addresses are 00 through 63.

Set the node address using either the rotary switches, RSNetWorx for
DeviceNet, DeviceNetManager, or another software configuration
tool. Setting the switches at any number from 64 to 99 lets the
software have address control.

Each module is shipped set for node address 63. Remove the caps on
the front of the module to access the switches. The two switches are:

• X10 (most significant digit) - left side of module

• X1 (least significant digit) - right side of module

To reset th e nod e addre ss, use a small bla de scre wdri ver to ro tate th e
switches. Line up the small black dot on the switch with the number
setting you wish to use and then cycle power.

The rotary switches are read periodically. If the switches have been
changed since the last time they were read and they no longer match
the on line address, a minor fault will occur, which is indicated by a
flashing red MOD LED. Settings between 64 and 99 cause the mod ule
to use the

last valid node address stored internally. Example: The last
setting internally was 40. If a change is made to 68, and th en you
power up, the address will default to 40.

Set Node Address
This example shows the default
node address set at 63.

31433-M

The module is equipped with AutoBaud detect. AutoBaud lets the
module read the settings already in use on your DeviceNet network
and automatically adjusts to follow those settings.

Mount the Module

Each module has two sets of mounting holes that are used to mount
the module directly to a panel or machine. The module can be fron t
or side mounted. Mounting holes accommodate #6 (M3) pan head
screws. The torque specification is 6 in-lbs.
