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.

Preface
Purpose of This Manual
This manual describes how to install, configure, and troubleshoot your
POINT I/O modules.
The POINT I/O modules in this manual are DeviceNet ready. Each module
can exist on the DeviceNet network as one of the following:
•As an individual node
•With an adapter (catalog number 1734-ADN or 1734-ADNX) as a
single node
When using these POINT I/O modules with an adapter, use this manual in
conjunction with the user manual for the adapter you are using as shown in the
table.
For applications using these modules in a network with a 1734-PDN
DeviceNet Communication Interface, or a 1734D-xx POINTBlock I/O
module, this user manual is the primary documentation.
Who Should Use This
Manual
In this manual, we assume you know how to do the following:
•Use RSNetWorx software or similar configuration software to set up
and calibrate these modules.
•Have the capability to download and use electronic data sheet (EDS)
files.
If you do not, refer to your software documentation or online help before
attempting to use these modules.
When Using POINT I/O
Modules on This
Network

This table lists the 1734D POINTBlock modules.
Input Modules
For input modules, dc inputs are 24V dc nominal, with an input range of
10…28.8V dc, and are offered with 2, 4,or 8 sinking style inputs, or 2, 4, or 8
sourcing style inputs. The 1734-IB2, 1734-IB4, 1734-IB4D, and 1734-IB8
input modules are sinking modules. The 1734-IV2, 1734-IV4, and 1734-IV8
modules are sourcing input modules.
For input modules, ac inputs are 120V ac nominal with an input range of
85…132V ac, or 220V ac nominal with an input range of 159…264V ac, with
sinking inputs.
Features of the all input modules include the following:
•Autobaud (will match baud of existing devices on the network)
•Selectable input filter times (0…65 ms with 1 ms default)
•Sequential auto addressing
Output Modules
The 1734-OB2, 1734-OB4, 1734-OB8, 1734-OB2E, 1734-OB4E, and
1734-OB8E dc output modules have current limited sourcing outputs, which
source a positive voltage of up to 1 A with respect to their dc return per
channel. The 1734-OB2EP sources a positive voltage of up to 2 A with respect
to its dc return per channel. The outputs are not isolated from each other. For
these modules, dc outputs are 24V dc nominal, with a range of 10…28.8V dc.
A number of output diagnostic features are incorporated to assist in
troubleshooting. The 1734-OB2E, 1734-OB2EP, 1734-OB4E, and
1734-OB8E modules feature the following:
•Output diagnostics (short circuit and wire-off indication and reporting
bits per channel)
•Current limited outputs

About the Modules 19
•Autobaud (will match baud of existing devices on the network)
•Sequential auto addressing
The 1734-OV2E, 1734-OV4E, and 1734-OV8E modules are protected sink
output modules protected to 1 A. The outputs are not isolated from each
other. For these modules, dc outputs are 24V dc nominal, with a range of
10…28.8V dc. A number of output diagnostic features are incorporated to
assist in troubleshooting. The 1734-OV2E, 1734-OV4E, and 1734-OV8E
modules feature the following (note that 1734-OV2E, 1734-OV4E, and
1734-OV8E modules have no wire-off indication):
•Output diagnostics (short circuit and reporting bits per channel)
•Current limited outputs
•Autobaud (will match baud of existing devices on the network)
•Sequential auto addressing
The 1734-OA2 and 1734-OA4 ac output modules have sourcing outputs,
which source a voltage of up to 0.75 A per channel. The outputs are not
isolated from each other. For this module, ac outputs are 120/220V ac
nominal, with a range of 74…264V dc. The 1734-OA2 and 1734-OA4
modules feature the following:
•Autobaud (will match baud of existing devices on the network)
•Sequential auto addressing
Relay Output Modules
Two versions of relay modules are:
•1734-OW2, 1734-OW4 relay module.
•1734-OX2 relay module.
The 1734-OW2 and 1734-OW4 relay outputs are Type A (Normally Open),
the 1734-OX2 relay outputs are Type 2 Form C. Both modules’ outputs sink or
source a current with respect to power or return. Contact outputs are isolated
from each other. Each output is rated 5…240V rms at 2 A (current is load
dependant). Features include:
•Autobaud (will match baud of existing devices on the network).
•Sequential auto addressing.

20 About the Modules
Analog Modules
The 1734 analog modules consist of input modules (1734-IE2C and
1734-IE2V) and output modules (1734-OE2C and 1734-OE2V). Each
module has two single-ended, non-isolated channels.
The features of the analog modules depend on the type of analog module:
input or output. These are features common to both input and output
modules.
•Data - The current input and output modules operate in unipolar mode
only. Voltage input and output modules operate in unipolar or bipolar
modes. Data returned from the module is scaled by the user to any 16
bit signed integer
(–32,768...+32,767).
•Input modules produce 6 bytes of data.
–Channel 0 Data (2 bytes)
–Channel 1 Data (2 bytes)
–Channel 0 Status (1 byte)
–Channel 1 Status (1 byte)
•Output modules consume 4 bytes of data.
–Channel 0 Data (2 bytes)
–Channel 1 Data (2 bytes)
•Output modules produce 2 bytes of data.
–Channel 0 Status (1 byte)
–Channel 1 Status (1 byte)
•Operational modes
–Current - two modes
•0 to 20 mA
•4 to 20 mA (default mode)
–Voltage - two modes
•0 to 10V (default mode)
•-10 to +10V
•Individually set channel mode
•Scaling - conversion to engineering units
