This user manual will help you set up and configure the ILX34-MBS module. You should
be somewhat familiar with the following:
Rockwell Automation® Studio 5000 Logix Designer v21 (for CompactLogix L1
processors) or Rockwell Automation® RSLogix™ 5000 version 16 or greater (for
1734 Point I/O adapters).
Hardware Installation and Wiring
1.1 ILX34-MBS Overview
The ILX34-MBS is the ideal solution for the many distributed I/O applications where
Modbus connectivity can be integrated into an Allen Bradley System. The ILX34-
MBSxxx is configured using Rockwell Automation Studio 5000 (CompactLogix L1) and
RSLogix 5000 (Point I/O Controllers). The modules work in both the 1734 Point I/O
adapters and the CompactLogix L1 processors.
1.2 Package Contents
The following components are included with your ILX34-MBS adapter, and are required
for installation and configuration.

2.1 Installing the Mounting Base/Wiring Base Assembly
The wiring base assembly consists of a mounting base and a removable terminal block.
You can install the assembly or just the mounting base. Perform the following to install
the base/wiring base assembly:
1 Position the mounting base/wiring base assembly vertically above the installed
units (adapter, power supply, or existing module).
2 Slide the mounting base down allowing the interlocking side pieces to engage the
adjacent module or adapter.
3 Press firmly to seat the mounting base on the DIN Rail. The mounting base
snaps into place.
4 To remove the mounting base from the DIN rail, remove any installed module
(and any module immediately to the right) and use a small blade screwdriver to
rotate the DIN rail locking screw to a vertical position. This releases the locking
mechanism. Lift straight up to remove the mounting base.
5 Repeat this procedure for the next mounting base assembly.

2.2 Installing an I/O Module
Make sure that the mounting base is correctly keyed before installing the module into the
mounting base. In addition, make sure the mounting base locking screw is positioned
horizontal referenced to the base.
Warning: When you insert or remove the module while backplane 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 non-hazardous before proceeding.
1 Using a blade screwdriver, rotate the key switch on the mounting base clockwise
until the number required for the type of module being installed aligns with the
notch in the base.
2 Make certain the DIN-rail locking screw is in the horizontal position. You cannot
insert the module if the locking mechanism is unlocked.
3 Insert the module straight down into the mounting base and press to secure. The
module locks into place.

2.3 Installing the Removable Terminal Block
A removable terminal block is supplied with the mounting base assembly. To remove,
pull up on the RTB handle. This allows the base to be removed and replaced as
necessary without removing any of the wiring. The following instructions show how to
reinsert the removable terminal block:
1 Insert the RTB end opposite the handle into the base unit. This end has a curved
section that engages with the mounting base.
Warning: When you connect or disconnect the Removable Terminal Block (RTB) with the 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 non-hazardous before proceeding.
2 Rotate the terminal block into the mounting base until it locks itself in place.
3 If an I/O module is installed, snap the RTB handle into place on the module.

2.4 Removing a Mounting Base
In order to remove a mounting base, you must remove any installed module, and
remove the Removable Terminal Block (if wired).
1 Unlatch the RTB handle on the I/O module.
2 Pull on the RTB handle to remove the Removable Terminal Block.
Warning: When you connect or disconnect the Removable Terminal Block (RTB) with the 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 non-hazardous before proceeding.
3 Press on the module lock on the top of the module and pull up on the I/O module
to remove from the base.
Warning: When you insert or remove the module while backplane power is on, an electrical arc
can occur. This could cause an explosion in a hazardous location.
Be sure that power is removed or the area is non-hazardous before proceeding.
4 Remove the module to the right of the base. The interlocking portion of the base
sits under the adjacent module.
5 Use a small screwdriver to rotate the orange DIN-rail locking screw on the
mounting base to a vertical position. This releases the locking mechanism.
6 Lift the mounting base and remove.

2.5 Connecting Power
Refer to the appropriate L1Y or Remote Adapter installation guides for adapter
configuration instructions.
2.5.1 CompactLogix L16/L18 Processor Power Connectivity
When using an L16/L18 CompactLogix controller, examine the side labeling of the
controller to determine what Series it is. It will be listed next to the model number. The
device power specification is 10 to 28.8 VDC.
There are two Series of the L16/L18 controllers:
Series A requires two separate NEC Class 2 24V power supplies for the
controller power and field power.
Series B uses a single 24V power supply and requires that the field power be
jumped from the controller power. The VDC+ should be jumped to the FP+, and
the VDC- should be jumped to the FP- as shown below. It uses isolated circuits
and does not require a NEC Class 2 rated unit.
VDC+ to FP+
VDC- to FP-

Caution: Do not connect 120/240V AC power to this supply.
Warning: 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.
