ArmorPoint 24V dc 4-channel Digital Input
Module with Diagnostics

Catalog Number 1738-IB4DM12

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 than IP67 may require an additional
appropriate housing.) I/O connectors are sealed M8 (pico), M12 (micro) or
M23 styles. The mounting base ships with the module.

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

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 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.

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 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.

• When not in use, store the equipment in appropriate static-safe

packaging.
