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.rockwellautomation.com/literature/) 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.

Purpose of This Manual
This manual provides information on installation, setting, and reading your
diagnostics on the 1794-IB16D and the 1794-OB16D Diagnostic modules.
Important Warnings and
Cautions
Obey the following warnings and cautions when installing or using these
modules.

ATTENTION: Environment and Enclosure
This equipment is intended for use in a Pollution Degree 2 industrial
environment, 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 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 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.
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 Industrial Automation Wiring and Grounding
Guidelines, Allen-Bradley publication 1770-4.1, for additional installation
requirements pertaining to this equipment.

8Rockwell Automation Publication 1794-UM061B-EN-P - March 2020
Preface
WARNING: When you insert or remove the module while backplane power
is on, an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
ATTENTION: FLEX 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 (such as aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or
intermittent grounding.
ATTENTION: Prevent 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.
ATTENTION: During mounting of all devices, be sure that all debris (such as
metal chips or wire strands) is kept from falling into the module. Debris that
falls into the module could cause damage on power-up.

Preface
North American Hazardous Location Approval
The 1794-IB16D and 1794-OB16D diagnostic modules are North American
Hazardous Location approved.
The following information applies when
operating this equipment in hazardous
locations:
Informations sur l’utilisation de cet
équipement en environnements dangereux :
Products marked “CL I, DIV 2, GP A, B, C, D”
are suitable for use in Class I Division 2
Groups A, B, C, D, Hazardous Locations and
nonhazardous locations only. Each product is
supplied with markings on the rating
nameplate indicating the hazardous location
temperature code. When combining products
within a system, the most adverse
temperature code (lowest “T” number) may be
used to help determine the overall
temperature code of the system. Combinations
of equipment in your system are subject to
investigation by the local Authority Having
Jurisdiction at the time of installation.
Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne
conviennent qu’à une utilisation en environnements
de Classe I Division 2 Groupes A, B, C, D dangereux
et non dangereux. Chaque produit est livré avec des
marquages sur sa plaque d’identification qui
indiquent le code de température pour les
environnements dangereux. Lorsque plusieurs
produits sont combinés dans un système, le code
de température le plus défavorable (code de
température le plus faible) peut être utilisé pour
déterminer le code de température global du
système. Les combinaisons d’équipements dans le
système sont sujettes à inspection par les autorités
locales qualifiées au moment de l’installation.
EXPLOSION HAZARD
Do not disconnect
equipment unless power
has been removed or the
area is known to be
nonhazardous.
Do not disconnect
connections to this
equipment unless power
has been removed or the
area is known to be
nonhazardous. Secure any
external connections that
mate to this equipment by
using screws, sliding
latches, threaded
connectors, or other means
provided with this product.
Substitution of
components may impair
suitability for Class I,
Division 2.
If this product contains
batteries, they must only be
changed in an area known
to be nonhazardous.
RISQUE D’EXPLOSION
Couper le courant ou s’assurer
que l’environnement est classé
non dangereux avant de
débrancher l'équipement.
Couper le courant ou s'assurer
que l’environnement est classé
non dangereux avant de
débrancher les connecteurs. Fixer
tous les connecteurs externes
reliés à cet équipement à l'aide
de vis, loquets coulissants,
connecteurs filetés ou autres
moyens fournis avec ce produit.
La substitution de composants
peut rendre cet équipement
inadapté à une utilisation en
environnement de Classe I,
Division 2.
S’assurer que l’environnement
est classé non dangereux avant
de changer les piles.
