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.

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.

Understand Short-circuit Detection
Understand Open-wire Detection
The sensor source voltage (SSV) for each input is protected against short
circuits. For currents above 200 mA, a fault signal is issued and the input LED
indicator is illuminated solid red. A thermally-actuated smart-power device or
PTC is used as the protection means. On a per-input basis, the circuit and
produced data automatically reset and SSV energizes upon removal of the
short circuit. An individual fault signal is issued for each shorted SSV
condition.
The shorted input LED indicator illuminates red to denote short-circuit fault
status.
See the section on interpreting LED indicators for related information.
When the SSV is loaded to the maximum rated current of 50 mA, a voltage
drop of as much as 2.5V dc can exist between the user auxiliary power and the
SSV connection. For example, for a supply of 10V dc to a sensor with power
derived from the SSV, a supply of 12.5V dc is needed at the auxiliary power
connection.
Sensor source voltage (SSV) current for each input is monitored. Monitoring is
accomplished in the SSV leg to accommodate the largest number of sensors
possible. For currents below 0.5 mA, a fault signal is issued and the input's
LED indicator blinks red. On a per-input basis, the circuit and produced data
automatically reset upon removal of the open-wire condition. See the
information about interpreting LED indicators for related information.
By using a configuration tool, you can disable the open- wire diagnostics on an
input-point basis to keep unused input indicators from turning red and
signaling a fault when an input is not in use. Enabling or disabling input-point
level open-wire diagnostics is implemented via the module’s EDS file, GSD
file, or Logix profile and its firmware.
You can also disable all the open-wire diagnostics, using a single entry via the
software user interface. The default configuration has all four input channels’s
open-wire indication enabled.
If a sensor with a dry contact output is used, wire one side of the contact to
the SSV terminal for the corresponding input. Wire the other side of the
contact to the input. Additionally, place a shunt resistor in parallel with the
contact, at the sensor, to cause greater than 0.5 mA to be drawn through the
SSV terminal at all times.

Wire the Module
Following are wiring instructions for the module.
ATTENTION
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).
