ArmorPoint 24V dc Analog Input Modules,
Series A
Catalog Numbers 1738-IE2CM12, 1738-IE2VM12
The ArmorPoint I/O family consists of modular I/O modules. The
sealed IP67 housing of these modules requires no enclosure. (Note
that environmental requirements other th an IP 67 may require an
additional appropriate housing.) I/O connectors are sealed M12 style.
The mounting base ships with the module. The 1738-IE2CM12 and
1738-IE2VM12 modules are shown below.

SHOCK HAZARD
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.literature.rockwellautomation.com) describes some important differences between solid state
equipment and hard-wired electromechanical devices. Because of thi s 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

ATTENTION
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 Grou p 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.

ATTENTION
Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic dischar ge,
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.
To mount the I/O base on a wall or panel, use the screw holes
provided in the base.

Mounting base
Install the mounting base as follows:
1. Lay out the required points as shown above in the drilling
dimension drawing.
2. Drill the necessary holes for #8 (M4) machine or self-tapping
screws.
3. Mount the base using #8 (M4) screws.
4. Ground the system using the ground lug connection.
The ground lug connection is also a mounting hole.
