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.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.
Reproduction of the contents of this manual, in whole or in part, without written
permission of Rockwell Automation, Inc. is prohibited.
Throughout this manual, when necessary, we use notes to make you aware of
safety considerations.
WARNING
Identifies information about practices or circumstances
that can cause an explosion in a hazardous environment,
which may lead to personal injury or death, property
damage, or economic loss.
IMPORTANT
Identifies information that is critical for successful
application and understanding of the product.
ATTENTION
Identifies information about practices or circumstances that can
lead to personal injury or death, property damage, or economic
loss. Attentions help you identify a hazard, avoid a hazard and
recognize the consequences.
SHOCK HAZARD
Labels may be located on or inside the drive to alert
people that dangerous voltage may be present.
BURN HAZARD
Labels may be located on or inside the drive to alert
people that surfaces may be dangerous temperatures.

Preface
Introduction
The purpose for showing these connection diagrams here is to
illustrate the following attributes of each I/O module, I/O block, or
fixed I/O controller:
• the number of inputs and/or outputs
• whether there is a single common for all I/O, a common for a
set of I/O separate from other sets of I/O, or a signal return for
each I/O circuit so that each I/O circuit is isolated from all
others
• whether an output is a current source or a current sink
• whether an input is a source load or a sink load
To fit them into this concise format, these diagrams are intentionally
simplified to the point that they do not show the type of cables,
twisted pairs, cable shields or the grounding of cable shields. We
make an exception where the cable shield must be connected at an
I/O terminal.
For those input modules or blocks that can tolerate the leakage
current of proximity sensors, we usually show a proximity sensor at
one input and hard contacts at the others for ease of illustration.
IMPORTANT
Many of the catalog numbers included in this
publication have specific wiring guidelines and
recommendations that are listed in the product’s
technical documentation (e.g. installation instructions
or user manuals) but not here because the purpose
of this publication is to show connection diagrams
and basic information required to wire each I/O
module.
For a full description of how to use each of the
catalog numbers listed in this publication, see the
individual product’s technical documentation.
