This ArmorBlock MaXum™ I/O module (Cat. No. 1792D-12BVT4D) 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 12 inputs and 4 outputs accessed through Y splitter
cables. Inputs are 24V dc automatically configured for PNP (sourcing)
or NPN (sinking) devices. Four self-protected 24V dc outputs can
provide up to 2.0 amp each. Diagnostic features are short circuit,
open wire and no load detection reported to the connector level for
inputs, to point level for outputs. Local logic control has been added
to the Series B version of this product.

ArmorBlock MaXum 12 Input/ 4 Output Module Series B 3
Install Your ArmorBlock MaXum I/O Module
To install the module you must:
• Set the node address
• Mount the module to the cable base
• Connect the input/output cord sets to the MaXum module
• Communicate with your ArmorBlock MaXum I/O module
Each of these steps is explained in the following procedures.
Set the Node Address
Valid node addresses are 00 to 63.
Set the node address using the rotary switches, RSNetWorx for
DeviceNet™, 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.

4 ArmorBlock MaXum 12 Input/ 4 Output Module Series B
Refer to the illustration of the node address below.
41462
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.
Mount the Module to the Cable Base
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
Publication 1792D-IN004B-EN-P - August 2000
The cable base should already be installed. See
publication 1792D-IN036B-EN-P (CB18P) or
1792D-IN009B-EN-P (CBFM, CB12) 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.
Note: Dimensions change according to the cable base and module
combination used.

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. This
product has two inputs or outputs per I/O connector. Use a “Y”
splitter cable for access to all I/O connections.
Publication 1792D-IN004B-EN-P - August 2000

Molded I/O cables with LEDs embedded in the connector are
incompatible with MaXum universal sink/source inputs. Please refer
to publication 889-5.0 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.
ATTENTION
• 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.

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 4 Bytes
Polled 1 Byte 4 Bytes
Change-of-State 1 Byte 4 Bytes
Publication 1792D-IN004B-EN-P - August 2000
8 ArmorBlock MaXum 12 Input/ 4 Output Module Series B
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 device - a master initiates communication by sending its
polled I/O message to the module. The 12 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 device - 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.
