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.
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.

1797-IE8 and 1797-IE8NF Field Transmitter Supply Characteristic
The field transmitter supply can be modeled as a 21.5V source with a 273 Ω
series resistance. (See the following 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 ≈21.5V for load currents of 0 mA.
•If the load is more than ≈680 Ωbut less than ∞Ω, the transmitter
supply is in a constant resistance region (≈273 Ω).
•For load impedance between 0 and ≈680 Ω, the transmitter supply
current is in constant current mode (≈22 mA).
If an intrinsic safety fault occurs in the field transmitter supply of any channel,
every channel’s field transmitter power is shutdown.
The following graph depicts the typical transmitter load characteristic.
The normal module field side power consumption is 7.5 W when all channel
21.5V sources (+) are loaded. If field devices are used that are powered
separately, the module field-side power consumption can be determined by
Field_Side_Power = 9.5V x (300 mA + n x 55 mA). Where n is the number of
field devices that are supplied by the 1797-IE8 or 1797-IE8NF.

1797-IE8H Field Transmitter Supply Characteristic
The field transmitter supply can be modeled as a 23.7V source with a 273 Ω
series resistance. (See the following 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 ≈23.7V for load currents of 0 mA.
•If the load is more than ≈750 Ωbut less than ∞Ω, the transmitter
supply is in a constant resistance region (≈273 Ω).
•For load impedance between 0 and ≈750 Ω, the transmitter supply
current is controlled by the field device to a maximum of ≈22 mA.
If an intrinsic safety fault occurs in the field transmitter supply of any channel,
every channel’s field transmitter power is shutdown.
The following graph depicts the typical transmitter load characteristic.
The normal module field side power consumption is 7.1 W when all channel
23.7V sources (+) are loaded. If field devices are used that are powered
separately, the module field-side power consumption can be determined by
Field_Side_Power = 9.5V x (180 mA + n x 69 mA). Where n is the number of
field devices that are supplied by the 1797-IE8H.
