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
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.
, for additional installation requirements.
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.

About the Modules
The ArmorPoint I/O family consists of modular I/O modules. The sealed
IP67 housing of these modules requires no enclosure when used with IP67
certified cables. (Note that environmental requirements other than IP67 may
require an additional appropriate housing.) I/O connectors are sealed DB25,
M12 (micro) or M23 styles. The mounting base ships with the module. The
1738-OB16E19M23, 1738-OB16EM12, 1738-OB16E25DS and
1738-IB16DM12 are shown below.

Mount the I/O Base
To mount the base on a wall or panel, use the screw holes provided in the
base.
The module must be mounted on a grounded metal mounting plate or other
conductive surface.
Refer to the Drilling Dimensions illustration of the base with an adapter to
help you mount the base.
Drilling Dimensions
You can only use the 1738-EP24DC expansion power unit with the 1738
ArmorPoint I/O adapters.

To comply with the CE Low Voltage Directive (LVD), this equipment must be
powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
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 M4 (#8) machine or self-tapping screws.
3. Mount the base using M4 (#8) screws.
4. Ground the system using the ground lug connection.
The ground lug connection is also a mounting hole.

Install the Digital Module
To install the digital module, proceed as follows:
1. Using a bladed screwdriver, rotate the keyswitch on the mounting base
clockwise until the number 1 aligns with the notch in the base.
2. Position the module vertically above the mounting base.
The module bridges two bases.
3. Push the module down until it engages the latching mechanism.
You hear a click sound when the module is properly engaged.
The locking mechanism locks the module to the base.

Communicate with Your Module
I/O messages are sent to (consumed) and received from (produced) the
ArmorPoint I/O modules. Messages are mapped into the processor’s
memory. ArmorPoint I/O output modules produce 1 byte of input data
(scanner Rx - status). They consume 2 Bytes of I/O data (scanner Tx).
ArmorPoint I/O input modules produce 2 or 3 bytes of input data (scanner
Rx - status). They do not consume I/O data (scanner Tx).
