Environment and Enclosure
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
meters 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 "enclosed"
equipment. It should not require additional
system enclosure when used in locations
consistent with the enclosure type ratings stated
in the Specifications section of this publication.
Subsequent sections of this publication may
contain additional information regarding specific
enclosure type ratings, beyond what this product
provides, that are required to comply with
certain product safety certifications.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for
explanations of the degrees of protection
provided by different types of enclosure. Also,
see the appropriate sections in this publication,
as well as the Allen-Bradley publication 1770-4.1
("Industrial Automation Wiring and Grounding
Guidelines"), for additional installation
requirements pertaining to this equipment.

ATTENTION

Install Your High Current I/O Module
To install the module you must:
• Set the node address
• Mount the module
• Connect the cable assembly to the module
• Connect the DeviceNet cable to the module
• Communicate with your ArmorBlock I/O module
More detailed information about each of these steps is in the
following procedures.
Preventing Electrostatic Discharge
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.
• If available, use a static-safe workstation.
• When not in use, store the equipment in
appropriate static-safe packaging.
Set the Node Address
Valid node addresses are 00 to 63.
Set the node address using the rotary switches, RSNetWorx for
DeviceNet™, DeviceNetManager™, or another software configuration
tool. Setting the switches between 64 and 99 lets the software have
address control.
Each module is shipped with the node address set to 63 in the
module’s memory. The rotary switches are set for position 99 at
shipment. The switches are located on the bottom of the module.
Publication 1792D-IN005D-EN-P - February 2002
High Current 8 Input/8 Output ArmorBlock I/O Module Series B 5
The two switches are:
• MSD (most significant digit)
• LSD (least significant digit)
To reset the node address, use a small blade screwdriver to rotate the
switches. Line up the small arrow on the switch with the number
setting you wish to use.
The rotary switches are read at module power up only. Settings
between 64 and 99 cause the module to use the last valid node
address stored internally. Example: The last setting was 40. If a
change is made to 68, and then you power up, the address will
default to 40. Use the mini caps to cover and seal node address
switch ports.
Refer to the illustration of the rotary switches below.

MSD
LSD
The module is equipped with AutoBaud detect. AutoBaud lets the
module read the settings already in use on your DeviceNet network
and automatically adjusts to follow those settings. The module is
shipped with AutoBaud enabled.
Mount the Module
1. Place the module against the panel where you want it
mounted.
2. Drill holes in the panel that are aligned with the moving holes
on the module.
Publication 1792D-IN005D-EN-P - February 2002

3. Place screws through each of the 4 mounting holes and
tighten the screws until the module is firmly in place.

Connect the Cable Assembly to the Module
Inputs, outputs, and power can either be wired directly to a mating
connector, or through a cable assembly.
Connection Using a Connector Assembly
Use the Allen-Bradley user-fabricated connector assembly, catalog
number 1792D-88HCCON, with a hand crimp tool and follow the
instructions to crimp connector contacts onto field wires. (Purchase
the hand crimp tool from Positronic Industries, Inc., part number
9501 and 9502-1). See the connector pinouts on the next page.
ATTENTION
For maximum noise immunity, input cable return
wires must be properly terminated. When inputs
are connected in loopback, return wires should
be connected together.

Communicate with Your ArmorBlock I/O Module
This High Current module’s I/O is exchanged with the master
through a polled, cyclic, or change-of-state connection.
The module produces and consumes I/O data as follows:
Type of I/O Connections Consumes Produces
Polled 1 Byte 3 Bytes
Cyclic 1 Byte 3 Bytes
Change-of-State 1 Byte 3 Bytes
Polled - master initiates communication by sending its polled I/O
message to the module. The module consumes the message, updates
any outputs, and produces a response. If inputs are present, the
response contains the input data.
Cyclic - allows configuration of the block as an I/O client. The block
will produce and consume its I/O cyclically at the rate configured.
Publication 1792D-IN005D-EN-P - February 2002
10 High Current 8 Input/8 Output ArmorBlock I/O Module Series B
Change-of-State - productions occur when an input changes or a
fault condition occurs. If no input or fault condition change occurs
within the expected packet rate, a heartbeat production occurs. This
heartbeat production tells the scanner module that the I/O module is
alive and ready to communicate. Consumption occurs when data
changes and the master produces new input data to the I/O block.
