Environment and Enclosure
POINTBlock dc 8 Input/8 Relay Output Module 3
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 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.
Besides 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.

Prevent Electrostatic Discharge
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.

North American Hazardous Location Approval
The following information applies when
operating this equipment in hazardous
locations
Products marked CL I, DIV 2, GP A, B, C, D are
suitable for use in Class I Division 2 Groups A, B,
C, D, Hazardous Locations and nonhazardous
locations only. Each product is supplied with
markings on the rating nameplate indicating the
hazardous location temperature code. When
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.
EXPLOSION HAZARD -
WARNING AVERTISSEMENT
• Do not disconnect equipment unless
power has been removed or the area
is known to be nonhazardous.
• Do not disconnect connections to
this equipment unless power has
been removed or the area is known
to be nonhazardous. Secure any
external connections that mate to
this equipment by using screws,
sliding latches, threaded
connectors, or other means provided
with this product.
• Substitution of components may
impair suitability for Class I,
Division 2.
• If this product contains batteries,
they must only be changed in an
area known to be nonhazardous.

About the Module
This 1734D input/output module is a DIN-rail mounted device with
an integrated DeviceNet communication interface, 8 inputs, 8 relay
outputs, removable terminations, and a POINTBus expansion port.
Use the expansion port to add a maximum of 12 additional POINT
I/O modules.
The module includes a non-isolated DeviceNet communication
interface. The 24V dc from the DeviceNet connection powers a
non-isolated dc/dc converter that generates +5V dc that powers the
POINTBlock electronics and connects to the POINTBus port to power
the expansion I/O electronics.
The 1734D-IB8XOW8 module uses cage-clamp termination and the
1734D-IB8XOW8S module uses spring-clamp termination.

Install the Module
For information about how to install the module, read this and the
sections on how to set the node address and wire the module.
ATTENTION
ATTENTION
This product is grounded through the DIN rail to chassis ground.
Use zinc-plated, yellow-chromated steel DIN rail to assure proper
grounding. Using other DIN rail materials, for example, aluminum
and plastic, which can corrode, oxidize or are poor conductors, can
result in improper or intermittent platform grounding.
Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
Whatever field power you supply is connected to the internal
field-power bus. For example, if 120V ac is applied to the power
connections, 120V ac is applied to the modules through the
internal field-power bus.
POINT I/O modules to the right of the module also have that
internal power bus voltage applied, unless you use a 1734-FPD
module to interrupt and change the field power-bus voltage.

WARNING
ATTENTION
WARNING
When you connect or disconnect the Removable Terminal Block
(RTB) with field-side power applied, 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.
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.
To comply with the CE low voltage directive (LVD), this equipment
must be powered from a source compliant with the following: safety
extra-low voltage (SELV) or protected extra-low voltage (PELV).
If you connect or disconnect wiring while the field-side power is on,
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.
