Installation Instructions
ArmorBlock MaXum I/O Cable Bases
DeviceNet Powered Outputs Series B
(Cat. No. 1792D-CB12JP and -CB18JP)
This version of the ArmorBlock MaXum™cable base lets you provide
power to outputs using DeviceNet™power. No additional auxiliary
power cabling is needed. The ArmorBlock MaXum Ι/Ο cable bases
mate with 4 or 8 connector modules, depending on your installation
requirements. No modification is required. Modules are
interchangeable with round media cable bases. This
interchangeability provides plug and play block upgrade capability
and easy field replacement. The completely assembled ArmorBlock
module and base requires no enclosure.
These instructions describe the installation of each cable base. The
catalog numbers for the cable bases are:
•1792D-CB12JP for 12mm drop cable installation, see page 5
•1792D-CB18JP for 18mm trunk or drop cable installation, see
page 6

Outputs Using DeviceNet Power

ArmorBlock MaXum I/O Cable Bases DeviceNet Powered Outputs Series B 3
Publication 1792D-IN001B-EN-P - September 2000
Powering Outputs Using DeviceNet Power
You can power some output devices from the DeviceNet network.
The application must allow the voltage to remain within the
DeviceNet specification limits of 11-25V dc. Most actuators need to be
powered by a separate power supply. They usually require more
power than is practically available from DeviceNet. Also, the large
voltage variation of 11-25V that DeviceNet allows is typically beyond
the range over which most available actuators or output devices can
safely operate.
You can use DeviceNet power to operate output devices such as
hydraulic and pneumatic solenoid valves, pilot and stack lights, and
motor starter coils with the following caution:
ATTENTION
!
Do not let DeviceNet voltage at the relevant
node exceed the output device’s acceptable
voltage range. Output devices rated 24V dc
rarely are specified to operate below 19.2V dc or
-20% of their 24V dc rating. Many only operate
down to 20.4V dc or -15% of the rated voltage.
This means that the DeviceNet network design
must not let the available voltage drop below
19.2 volts, for example, instead of the 11 volts
that the DeviceNet specification allows. This
higher lower voltage limit, which is within the
DeviceNet specification, will actually restrict the
distance of the DeviceNet network from what
would be possible if actuators were not utilizing
the DeviceNet power.
IMPORTANT Design your network so that sufficient voltage is
available to operate the output device wherever it
is installed. This is especially important when it is
connected at the farthest location from the power
supply.

Noise or Transient Protection
The typical actuators used in DeviceNet control systems utilize
inductive coils that generate transients when de-energized. Each
ArmorBlock MaXum output contains a diode which is across the load
device coil. As a precaution, also use an MOV varistor suppressor at
the 24V dc coil.
Package Contents for Cable Bases
Your package contains these installation instructions and the
following contents, depending on the base used:
(Please note: ArmorBlock MaXum modules are ordered and shipped
separately.)
Install Your ArmorBlock MaXum Cable Bases
To install the 1792-CB12JP and -CB18JP cable bases:
•Mount the cable base
•Attach the module to the base
•Attach the cables
These steps are discussed in the following procedures.
ATTENTION
!
Do not use DeviceNet power on dc coil
actuators that use economizing coils to operate.
They have high inrush currents.

Mount the Cable Base
The cable base can be mounted either vertically or horizontally, using
3 screws. Cable bases accommodate 4 or 8 connector ArmorBlock
MaXum modules. You must allow additional space for installation of
8 connector ArmorBlock MaXum modules. They are longer than the 4
connector modules.

Attach the Module
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.
The 1792D-CB12JP module is shown below.
IMPORTANT Make sure you properly align the screws to
complete the connections between the module
contacts and the cable contacts cafeteria.
