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.

POINT I/O 4 Channel IO-Link Master Module
Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in EN/IEC 60664-1),
at altitudes up to 2000 m (6562 ft) without derating.
This equipment is not intended for use in residential environments and may not
provide adequate protection to radio communication services in such environments.
This equipment is supplied as open-type equipment for indoor use. It must be
mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed to
prevent personal injury resulting from accessibility to live parts. The enclosure
must have suitable flame-retardant properties to prevent or minimize the spread
of flame, complying with a flame spread rating of 5V A or be approved for the
application if nonmetallic. The interior of the enclosure must be accessible only by
the use of a tool. Subsequent sections of this publication may contain more
information regarding specific enclosure type ratings that are required to comply
with certain product safety certifications.
In addition to this publication, see the following:
• Industrial AutomationWiring and Grounding Guidelines,
publication 1770-4.1, for additional installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of the
degrees of protection provided by enclosures.
ATTENTION: Read this document and the documents listed in the Additional
Resources section about installation, configuration, and operation of this
equipment before you install, configure, operate, or maintain this product. Users
are required to familiarize themselves with installation and wiring instructions in
addition to requirements of all applicable codes, laws, and standards.
Installation, adjustments, putting into service, use, assembly, disassembly, and
maintenance are required to be carried out by suitably trained personnel in
accordance with applicable code of practice. In case of malfunction or damage, no
attempts at repair should be made. The module should be returned to the
manufacturer for repair. Do not dismantle the module.

Prevent Electrostatic Discharge
Electrical Safety Considerations
ATTENTION: 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.
ATTENTION:
• This equipment is certified for use only within the surrounding air temperature
range of -20…+55 °C (-4…+131 °F). The equipment must not be used
outside of this range.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any
cleaning agents.
At the end of its life, this equipment should be collected separately from any
unsorted municipal waste.

POINT I/O 4 Channel IO-Link Master Module
Special Conditions for Safe Use
ATTENTION:
• This product is grounded through the DIN rail to chassis ground. Use zinc
plated chromate-passivated steel DIN rail to assure proper grounding. The use
of other DIN rail materials (for example, aluminum or plastic) that can corrode,
oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail
properly. Refer to Industrial AutomationWiring and Grounding Guidelines,
publication 1770-4.1, for more information.
• Do not remove or replace an Adapter Module while power is applied.
Interruption of the backplane can result in unintentional operation or
machine motion.
• Do not discard the end cap. Use this end cap to cover the exposed
interconnections on the last mounting base on the DIN rail. Failure to do so
could result in equipment damage or injury from electric shock.
• If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
ATTENTION: Do not wire more than two conductors on any single terminal.

POINT I/O 4 Channel IO-Link Master Module
About the Module
The POINT I/O 4 Channel IO-Link Master Module provides four channels
that can be individually configured as IO-Link master or as a standard digital I/
O module. The IO-Link channel master module can be configured to fit any
IO-Link and/or discrete application.
In IO-Link mode, the module supports four channels for IO-Link master
communication with IO-Link compatible devices. In standard digital I/O mode,
the module supports four channels of digital input or output. Standard digital
input channels support IEC61131-2 type 1 input. Channels can also be disabled
if not in use.
You must use this module with the 1734-AENT or 1734-AENTR, Series B
EtherNet/IP adapters, firmware revision 5.012 or later, and RSLogix 5000®/
Studio 5000® software, version 20 or later. Use this diagram to identify the
external features of the module.

Install the Mounting Base
To install the mounting base on the DIN rail, proceed as follows:
1. Position the mounting base vertically above the installed units (adapter,
power supply, or existing module).
2. Slide the mounting base down allowing the interlocking side pieces to
engage the adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail. The mounting
base snaps into place. Be sure that the orange DIN rail locking screw is in
the horizontal position and that it has engaged the DIN rail.
Install the Module
The module can be installed before or after base installation. Make sure that the
mounting base is correctly keyed before installing the module into the mounting
Slide the mounting base until the
interlocking side pieces engage the
adjacent module or adapter.

horizontal referenced to the base.
1. Using a bladed screwdriver, rotate the keyswitch on the mounting base
clockwise until the number required for the type of module being
installed aligns with the notch in the base.
2. Make certain the DIN rail locking screw is in the horizontal position.
You cannot insert the module if the locking mechanism is unlocked.
3. Insert the module straight down into the mounting base.

4. Press to secure. The module locks into place.
Install the Removable Terminal Block
A Removable Terminal Block (RTB) is supplied with your wiring base assembly.
To remove, pull up on the RTB handle. This allows the mounting base to be
removed and replaced as necessary without removing any of the wirings. To
reinsert the Removable Terminal Block, proceed as follows.
1. Insert the end opposite the handle into the base unit.
This end has a curved section that engages with the wiring base.
2. Rotate the terminal block into the wiring base until it locks itself
in place.
WARNING: When you connect or disconnect the Removable Terminal Block (RTB)
with field-side power applied, an electrical arc can occur.This can cause an
explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
