The ArmorPOINT® I/O family (Bulletin 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.) The I/O connector is sealed M23 style. The
mounting base ships with the module. The 1738-VHSC24M23 module is
shown below.

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.rockwellautomation.com/literature/) 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.

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.
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.
