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://literature.rockwellautomation.com) 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.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell
Automation, Inc., is prohibited.
Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

ATTENTION
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 (6562 ft)
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.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-4.1, for additional installation requirements.
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure
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.

Make sure all connectors and caps are securely tightened to properly seal the
connections against leaks and maintain IP enclosure type requirements.
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).
About the Module
The ArmorPoint I/O family (Cat. no. 1738) consists of modular I/O
modules. The sealed IP67 housing of these modules requires no enclosure.
(Note that environmental requirements other than IP67 may require an
additional appropriate housing.) I/O connectors are sealed M12 style. The
mounting base ships with the module. The 1738-OE4CM12 module is shown
below.

Mount the I/O Base
To mount the ArmorPoint I/O base on a wall or panel, use the screw holes
provided in the ArmorPoint base .
The ArmorPoint I/O module must be mounted on a grounded metal
mounting plate or other conductive surface.

1738-OE4CM12
Analog modules have earth grounded metal rings. This should be
considered when choosing shielded cables and grounding techniques.
Make sure all connectors and caps are securely tightened to properly seal the
connections against leaks and maintain IP enclosure type requirements.
Communicate With Your Module
I/O messages are sent to (consumed) and received from (produced) the
ArmorPoint I/O modules. These messages are mapped into the processor’s
memory. These ArmorPoint I/O analog output modules produce 4 bytes of
input data (scanner Rx - fault status). They consume 8 bytes of output data
(scanner Tx).
