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.

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 IEC
publication 60664-1), at altitudes up to 2000 m (6561 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 open-type equipment. 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 5VA, V2, V1, V0 (or
equivalent) if non-metallic. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain
product safety certifications.
In addition to this publication, see:
•Industrial Automation Wiring and Grounding Guidelines, for additional
installation requirements, 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.

combining products within a system, the most
adverse temperature code (lowest “T” number)
may be used to help determine the overall
temperature code of the system. Combinations
of equipment in your system are subject to
investigation by the local Authority Having
Jurisdiction at the time of installation.

Prevent Electrostatic Discharge
Identify Module Features
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.
The module has:
•a 4-character scrolling display.
•3 status indicators.
RIO indicates the status of the
network.
SYS indicates the connection to the
processor.
OK indicates the module’s own
internal state.
•a 3-pin Phoenix connector that
connects to the remote devices.

Prepare the Chassis for Module Installation
Before you install the 1757-ABRIO module, you must install and connect a
ProcessLogix or ControlLogix chassis and power supply.
Determine Module Slot Location
Chassis slots are numbered starting from the left, starting at 0. Slot 0 is the
first slot to the right of the power supply.
You can:
•use any size chassis.
•install the module in any available slot.
•install multiple 1757-ABRIO modules in the same chassis, depending
on how your power supply is rated.
Remove and Insertion Under Power
You can install or remove the module while the chassis is powered if you
observe these precautions.
WARNING When you insert or removethe module while backplane poweris on,
an electrical arc can occur. If you connect or disconnect the
communications cable with power applied to this module or any
device on the network, an electrical arc can occur. This could cause
an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
Repeated electrical arcing causes excessive wear to contacts on
both the module and its mating connector. Worn contacts may create
electrical resistance that can affect module operation.

Publication 1757-IN916C-EN-P - March 2008
Install the Module
To install the module, follow these steps.
1. Align the module circuit board with the top and bottom guides in the
chassis.
2. Slide the module into the chassis in the appropriate slot.
Make sure the module properly connects to the chassis backplane.
The module is fully installed when it is flush with the other installed
modules, and the module locking clips click into place.
3. To remove the module, push down on the locking clips at the top and
bottom of each module.
4. Slide the module out of the chassis.
ATTENTION Do not force the module into the backplane connector. If you cannot
seat the module with firm pressure, check the alignment. Forcing the
module into the chassis can damage the backplane connector or the
module.

Wire the Connector for the Remote I/O Network
Follow these steps to wire the connector.
1. Connect Line 1 of the remote I/O cable to the upper pin.
2. Connect the shield to the middle pin.
3. Connect Line 2 to the lower pin on the 1757-ABRIO.
4. Terminate both ends of a remote I/O network by using external
resistors attached to the physical ends of the network.
There should be two and terminators on the network.
Select Proper Resistor
Use 82 ohm resistors if the network operates at 230.4 kbps or if the network
operates at 57.6 kbps or 115.2 kbps and none of the devices in the table below
are present. The maximum number of devices on the network is 32.
Use 150 ohm resistors if the network contains any of the devices in the table
below, or if the network operates at 57.6 kbps or 115.2 kbps and you do not
require the network to support more than 16 devices.

Removing or Replacing the Module
If you are replacing an existing module with an identical one, and you want to
resume identical system operation, you must:
•install the new module in the same slot.
•run the configuration program and download the appropriate
configuration to the module.
Apply Chassis Power
Turn the rack power supply on.
Check Power Supply and Module Status
The rack power supply indicator should be green. The module OK status
indicator should be solid red immediately after you turn on the rack power
supply and then it turns solid green. Refer to the installation instructions for
your particular 1756 rack power supply for recommended actions for
checking your power supply.
Status Display Power-up Messages
The alphanumeric display shows the following messages at power-up.
If the indicator on the 1757-ABRIO module does not cycle through these
messages on powerup, refer to the Troubleshooting section of publication
1757-UM007C, the 1757-ABRIO User Manual.
