Installation Instructions
ArmorBlock MaXum 4 Input / 4 Output
Module with 8 Connectors, Series B
(Cat. No. 1792D-4BV4D)
42758
This ArmorBlock MaXum I/O module (Cat. No. 1792D-4BV4D) is a
stand-alone 24V dc I/O product which communicates via a
DeviceNet network. The sealed housing of this module requires no
enclosure.
This model has 4 inputs and 4 outputs with 8 connectors. Inputs are
24V dc automatically configured for PNP (sourcing) or NPN (sinking)
devices. Four self-protected 24V dc outputs can provide up to 0.5
amp each. Diagnostic features are short circuit, open wire, and no
load detection reported to the point level. Local logic control has
been added to this Series B product. The 1792D-4BVT4D also has 4
inputs and 4 outputs, but only 4 connectors. This new module gives
you complete single point diagnostics.

Install Your ArmorBlock MaXum I/O Module
To install module:
• Set the node address
• Mount the module to the cable base
• Connect the cord sets
• Communicate with the module
Set the Node Address
Valid node addresses are 00 to 63.
Set the node address using the rotary switches, RSNetWorx for
DeviceNet, DeviceNetManager, or other software configuration
tool. Setting the switches between 64 to 99 lets the software have
address control.
Each module is shipped set for node address 63. The switches are
located on the underside of the module. 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 black dot 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.

ArmorBlock MaXum 4 Input / 4 Output Module with 8 Connectors, Series B
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.
Install the Module
This module mounts to the following cable bases:
• 1792D-CBFM for KwikLink™ flat media installation
• 1792D-CB12 for 12mm drop cable installation
• 1792D-CB18P for round media DeviceNet and output power
• or other optional cable base assembly.
IMPORTANT
The cable base should already be installed. See
publication 1792D-IN009B-EN-P to install the cable
base.
To install the module:
IMPORTANT
Proper alignment of the screws is necessary to
complete the connections between the module
contacts and the cable contacts.
1. Position the module over the mounted cable base. Align the
three captive screws in the module with the accepting
receptacles in the base.
2. Tighten the screws with a torque of 8 inch-pounds to secure
the module to the base.

Connect the Input / Output Cord Sets to the MaXum
Module
This module uses 5 pin micro (12mm) style PCB mounted connectors.
Eight micro caps cover the connectors on your module. Remove the
caps and connect your cord sets to the appropriate ports.
Use the micro caps to cover and seal unused ports. Pinout diagrams
for the connectors are shown next.

Please refer to publication 889-CP001A-EN-P and 889-TD001A-EN-P
for Rockwell Automation cables and cord sets offerings.
IMPORTANT
If the devices (sensors) connected to the input
connections require Class 2 power to operate, the
DeviceNet connections of this equipment must be
powered by a Class 2 source.
• Make sure all connectors and caps are
securely tightened to properly seal the
connections against leaks and maintain IP67
requirements.
• For maximum noise immunity, input and
output cable return wires must be properly
terminated. When inputs and outputs are
connected in loopback, return wires should
be connected together.
• I/O cable length should be less than 30
meters.

Output Power and DeviceNet Cables
Output power and DeviceNet cables are described in the installation
publications for the cable base assembly of your choice. Refer to the

Communicate With Your ArmorBlock MaXum I/O
Module
This ArmorBlock module’s I/O is exchanged with the master through
a poll, change-of-state, or cyclic connection.
The module consumes and produces I/O data as follows:
Type of I/O Connections
Consumes
Produces
Cyclic
1 Byte
3 Bytes
Polled
1 Byte
3 Bytes
Change-of-State
1 Byte
3 Bytes
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.
Polled - a master initiates communication by sending its polled I/O
message to the module. The 4 input / 4 output module consumes the
message, updates outputs, and produces a response. The response
has input data, input faults, output faults, and the status of the
Auxiliary power.
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 output data to the I/O block.
