Installation Instructions
ArmorPoint Relay Output Modules, Series A
(Cat. No. 1738-OW4M12 and -OW4M12AC)
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 with either DC or AC keyed (micro) styles. The mounting
base ships with the module. The 1738-OW4M12 and -OW4M12AC
modules are 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.ab.com/manuals/gi) 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

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.
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.

Install the ArmorPoint
Relay Output Module
To install the ArmorPoint relay output module, proceed as follows.
1. Using a bladed screwdriver, rotate the keyswitch on the
mounting base clockwise until the number 7 aligns with the
notch in the base.
2. Position the module vertically above the mounting base. The
module will bridge two bases.

3. Push the module down until it engages the latching mechanism.
You will hear a clicking sound when the module is properly
engaged.
The locking mechanism will lock the module to the base.
Remove the ArmorPoint Relay Output Module From the
Mounting Base
To remove the module from the mounting base:
1. Put a flat blade screwdriver into the slot of the orange latching
mechanism.
2. Push the screwdriver toward the I/O module to disengage the
latch.
The module will lift up off the base.
3. Pull the module off of the base.

Communicate With
Your Module
I/O messages are sent to (consumed) and received from (produced)
the ArmorPoint I/O module. These messages are mapped into the
processor’s memory. The ArmorPoint I/O relay output module
consumes 1 byte of output data (scanner Tx - status). It does not
produce data (scanner Rx).
