Environment and Enclosure
ATTENTION
WARNING
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 11. Without appropriate precautions, there may be difficulties 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, for additional
installation requirements, Allen-Bradley publication 1770-4.1
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.

.
If 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
This product 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 (7.8 in.) and use
end-anchors appropriately.
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.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in
use.
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).

• 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 1,
Division 2.
• S’assurer que l’environnement est
classé non dangereux avant de
changer les piles.
For Class I Division 2 applications, use only Class I Division 2 Listed or
Recognized accessories and modules approved for use within 1794 platform.

About the Module
The HART analog modules can be used with ControlNet, Ethernet and
Profibus-DP (1794-APBDV1 only) adapters. When using the Series B module
with a Series B profile, you must have a ControlNet adapter Revision 5.1 or
higher or an Ethernet adapater Revision 4.2 or higher.
For this scenario (Series A profile with a Series B Module), the data maps
(input, configuration and extended configuration) are designated as Series A
Mode. Note, all other data maps are for a Series B module with a Series B
profile.
Only use the series A configuration when replacing a series A module with a
series B module. If you access the Series A configuration while using the
module as a series B unpredictably operation of the module may occur.
Install the Module
Read this for information about how to install the module. The module must
be used with a 1794-TB3G or 1794-TB3GS terminal base unit.
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.

Do not remove or replace a Terminal Base unit while power is applied.
Interruption of the backplane can result in unintentional operation or machine
motion.
You must disable keying in your profile when replacing a series A module with
a series B module.
To install the module on a 1794 terminal base, refer to the figure and
complete the following.
1. Rotate the keyswitch (1) on the terminal base (2) clockwise to position
3 as required for this type of module.
Do not change the position of the keyswitch after wiring the terminal base
unit.
2. Make sure the flexbus connector (3) is pushed all the way to the left to
connect with the neighboring terminal base or adapter.
You cannot install the module unless the connector is fully extended.
3. Make sure the pins on the bottom of the module are straight so they
align properly with the connector in the terminal base.
4. Position the module (4) with its alignment bar (5) aligned with the
groove (6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit,
noting that the module is seated when the latching mechanism (7) is
locked into the module.
6. Remove cap plug (8) and attach another terminal base unit to the right
of this terminal base unit if required.

Wire the Module
If you connect or disconnect wiring while the field-side 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.

Cyclic HART Input Data
The HART input data holds the primary variables for the "live" HART
device, and other information gathered during the normal HART scan.
Additional "documentary" data is available through the pass through message
interface in the device information tables. Pass through messages are defined
in detail in the User Manual.
The HART Input Data for a channel may be zeroes if HART communications is
disabled for that channel. For more information on disabling HART
communications, refer to the Disable HART communications and HART
Disable functions in the Configuration Map table.

current (sensed by the HART device on its own) received by the
1794-IE8H during HART communication in the background. This
functionality can be turned on by defining a HART read back threshold

whereby a parasitic current is bypassing the 1794-IE8H.

If there is no HART transmitter on the loop or the loop is not in the

This setting affects all channels using Data Format 2 or 6. It sets low,

Field Transmitter Supply Characteristic
The field transmitter supply can be modeled as a 23.7V source with a 273 Ω
series resistance see the Field Transmitter Load Characteristic graph. This
provides a simple and useful mechanism to determine transmitter and loop
compatibility.
The actual transmitter supply contains three ranges of impedance with the
following characteristics:
• The output voltage is
