Mechanical Dimensions
Units may be mounted to 35mm
“T” type DIN rail (35mm, type
EN50022), and side-by-side on
22.5mm (0.9-inch) centers.
WARNING: IEC Safety Standards
may require that this device be
mounted within an approved
metal enclosure or sub-system,
particularly for applications with
exposure to voltages greater than
or equal to 75VDC or 50VAC.
DIN Rail Mounting & Removal
Refer to the following figure for attaching and removing a unit from the DIN rail. A
spring-loaded DIN clip is located on the bottom side. The opposite rounded edge at
the bottom of the top side allows you to tilt the unit upward to lift it from the rail
while prying the spring clip back with a screwdriver. To attach the module to T-type
DIN rail, angle the top of the unit towards the rail and place the top groove of the
module over the upper lip of the DIN rail. Firmly push the unit downward towards
the rail until it snaps into place. To remove it from the DIN rail, first separate the
input terminal blocks from the bottom side of the module to create a clearance to
the DIN mounting area. You can use a screwdriver to pry the pluggable terminals
out of their sockets. Next, while holding the module in place from above, insert a
screwdriver along the bottom side path of the module to the DIN rail clip and use it
as a lever to force the DIN rail spring clip down while pulling the bottom of the
module outward until it disengages from the rail. Tilt it upward to lift it from the
rail.

ELECTRICAL CONNECTIONS
WARNING –EXPLOSION HAZARD –Do not disconnect equipment unless power has been
removed or the area is known to be non-hazardous.
WARNING –EXPLOSION HAZARD –Substitution of any components may impair suitability for
Class I, Division 2.
WARNING –EXPLOSION HAZARD –The area must be known to be non-hazardous before
servicing/replacing the unit and before installing.
Wire terminals can accommodate 14–26 AWG (2.08–0.13mm2) solid or stranded
wire with a minimum temperature rating of 85oC. I/O wiring may be shielded or
unshielded type. Terminals are pluggable and can be removed from their sockets by
prying outward from the top with a flat-head screwdriver blade. Strip back wire
insulation 0.25-inch on each lead and insert the wire ends into the cage clamp
connector of the terminal block. Use a screwdriver to tighten the screw by turning
it in a clockwise direction to secure the wire (use 0.5-0.6Nm torque). Since common
mode voltages can exist on I/O wiring, adequate wire insulation and proper wiring
practices are recommended. As a rule, I/O wires are normally separated from
power and network wiring for safety, as well as for low noise pickup.

Digital Input Connections
16 active-high inputs operate at
TTL thresholds and are wired to
accomplish loop-back monitoring
of the open-source, high-side
mosfet switches, or to monitor
field input levels with the tandem
output switch turned OFF. Inputs
include 10K pull-downs to Return
(RTN).
Inputs of this model are active-high and accept voltage levels up to 32V and use TTL
thresholds for logic transfer. They are pulled down to Return via 10K pull-down
resistors installed on the board and never float. Observe proper polarity when
making I/O connections. Refer to the following figures to wire inputs to this model.
IMPORTANT: You must keep the tandem output turned off when using the input to
sense voltage levels from the field to prevent contention between the field signal
and the output channel, which may be turned ON.
NOTE: You do not need to connect excitation if you are only using the input
channels to monitor field inputs. Excitation is only required to operate the outputs.

Digital Output Connections
16 open-source outputs operate as
high-side switches between EXC
and your load and include 10K
pull-downs to Return (RTN).
Outputs will source up to 250mA from the 6-32V excitation to each load. You must
connect Excitation to operate the outputs. Observe proper polarity when making
I/O connections. Refer to the following figures to wire the outputs of this model.
NOTE: You must connect EXC to a
voltage source from 6 to 32VDC to
operate the outputs, as the output
drivers are powered from the
excitation supply.
IMPORTANT –Add Protection with Inductive Loads: Outputs do include internal
reverse-bias shunt diodes to help protect the output switch from damage due to
high reverse-bias voltages generated when switching inductive loads. But you
should add external protection near the inductive load to prevent these transients
from being sent along the connection wires. Place a diode (1N4006 or equivalent)
across an inductive load with the cathode to (+) and the anode to (-).
For greater drive capability or for switching AC loads, it is common to use an
appropriately rated interposing relay. Add protection local to the relay as noted
above when driving inductive relay coils.
Per UL, when the outputs are used to drive interposing relays for switching AC or DC
devices of higher voltage/current, the coil ratings for the interposing relay shall not
exceed 24VDC, 100mA.

EMI Filter Installation
For low CE-rated radiated emissions, the use of split snap-on ferrite cores on all cables or
harnesses to/from the device as shown in the drawing on the next page is helpful. Use Laird
28A2029-0A2 or similar for I/O, Ethernet, and Power (order Acromag 4001-135) and Laird
28A0350-0B2 or similar for USB cables (Acromag 4001-136). Locate this ferrite by clamping it
outside of all input/output cables or wiring harnesses to/from the module (USB, Ethernet, I/O
group, DC power), and as close to the module as possible. While the use of these ferrites is
helpful to obtaining low CE-rated emissions, it may not be required for your application. Note
also that cables may share a ferrite, but it is not good practice to combine isolated circuits
inside the same ferrite. Separate isolated circuits for increased safety and greater noise
immunity.

Earth Ground Connections
The unit housing is plastic and does not require an earth ground connection to
itself. If the module is mounted in a metal housing, an earth ground wire
connection to the metal housing’s ground terminal (green screw) is usually required
using suitable wire per applicable codes.
Circuits wired to power, I/O, and the network should be earth grounded as reflected
in the connection diagrams. Note that for I/O, power, and excitation connections, it
is always best to apply earth ground closest to the module, but never at both ends
of a cable. Keeping this connection close to the module allows any destructive
transient energy to be safely shunted to earth ground along a short and local low
impedance path, helping to protect the circuit from damage. See the Electrical
Connections Drawings for I/O, power, and network ground connections.
Note: A USB isolator is recommended when connected to a grounded Personal
Computer for configuration purposes. This will avoid a potential ground loop that
can occur if the I/O signal is already earth grounded, as a PC commonly connects
earth ground at its USB port and this connects to USB signal and shield ground held
in common to the input circuit return of this module.

CONFIGURATION SOFTWARE
While this is an Ethernet/IP™ I/O module, it can only be configured and calibrated via its Configuration Software over a
USB connection to a Windows-based PC or laptop. USB saves you the trouble of having to already know its set IP address,
or having to change the address setting of your network interface card to match its domain to communicate with it. USB
software is contained in a zip file that can be downloaded free of charge from our web site at www.acromag.com. Look
for the software zip file 9500462 in the Documents and Downloads page for your XT product. Initially, you will have to
answer a few questions to open a user account and download this file to your computer. This zip file will extract to an
executable file, which installs modelconfig.exe executable files in an Acromag subdirectory off the Program Files directory
of your PC. Note that you must have administrator rights to download and install this software onto your PC or laptop.
Once you have installed the software, be sure to navigate to the Program Files\Acromag subdirectory and select the
correct modelconfig.exe software for your module. This same software is also included on a CDROM bundled with the
Configuration Kit XT-SIP (see Accessories) and may be downloaded from the web to ensure that the software is the most
up-to-date. The software is compatible with XP or later versions of the Windows operating system. The modelconfig.exe
software for this unit supports five other model variations—three models with 16 sinking outputs and active-low inputs,
and three models with 16 sourcing outputs and active-high inputs.
Quick Overview
After booting the Configuration software for this
model, the Device/ Communication Setup page will
appear. Once you select a device and click “Open”
to connect to an XT1122-000 model, your screen
will look similar to:
For a more detailed configuration procedure, see
the Configuration Step-by-Step section of the
Technical Reference on page 17 of this manual.
IMPORTANT: Delay clicking [Open] immediately
after power-up until it has established its Ethernet
connection (wait ~30 seconds after power-up to
give it time to initialize), otherwise data transfer or
timeout errors may result. If this occurs, turn
power off to the unit, close the software, then turn
power back on and reboot the software after unit
has powered up.
The initial configuration software screen for this model is shown at

CONFIGURATION STEP-BY-STEP
Getting Connected
This section will walk you through
the Connection-Configuration
process step-by-step. But before
you attempt to reconfigure this
module, please make the following
electrical connections.
1. Connect I/O: Refer to Input and Output Connections at the front of this
manual and connect your I/O as required for your application.
2. Connect Excitation (Required for Outputs): You cannot operate the output
channels of this model without connecting excitation across the EXC & RTN
terminals on the unit. You do not need to provide excitation if you are only
using the digital inputs to monitor field signals. Outputs of this model require
excitation from 6-32V (52Ma minimum). The actual required current capacity
will depend on the loads you are driving and your voltage level, but at full rated
load with 16 channels, your excitation supply must be able to deliver up to 4A
(See Excitation Connections).
3. Connect Power: You need to connect power from 12-32V to power this
module. You can choose to connect to Power via terminals on the unit, or via
optional terminals that make a connection to the module’s bus connector
along the DIN rail (See Power Connections). Current required will vary with
voltage level (refer to Specifications). Your supply must be able to drive at
least twice the maximum rated current for your voltage level
4. Connect to PC via USB: Refer to USB Connections of page 10 and connect the
module to your PC or laptop using the USB isolator and cables provided in
Configuration Kit XT-SIP.
Now that you have made your connections and applied power, you can
execute the XT11xxConfig.exe software to begin configuration of your unit
(software is compatible with XP or later versions of the Windows operating
system). Note that the same software is used for both DIO models, XT111x-
000 (with 16 sinking outputs) and XT112x-000 (with16 sourcing outputs).
IMPORTANT: Allow the unit to fully power-up and establish its Ethernet
connection before attempting to open USB communications with the unit using
the XT11xxconfig.exe software (wait ~30 seconds after powering-it up to give it
time to initialize).
Note that you do not connect your module to an Ethernet network to configure it.
It is instead configured for network operation by initially connecting to USB and a
host PC running model-specific configuration software. This has the advantage of
not having to know the module’s set IP address, or having to change the address
setting of your network card to match the module’s subnet address to talk to it.

Device/Communication Setup
After executing the Acromag Configuration software for this model, the screen shown below will appear, if you have not
already connected to your module via USB (note Device Select fields are blank under these conditions).
Connect your PC to the unit via USB and its model-serial information will appear in the Device field as shown in the screen
on the next page.
Device Select
If you are connected to more than one unit via a USB hub, you can use the Device scroll field to select another unit, using
the serial information suffix of the Model noted to discern one unit from another. Be sure to close the connection with a
previous unit before connecting to a new unit.
Once you have selected a device, click the [Open] button to open communications with the unit. If you wish to Open
communication with another device, be sure to first Close communication with the currently connected device.
After clicking [Open], the selected unit’s Model, Serial Number, Manufacturer, and connection status will be displayed as
shown on the next page.

Device/Communication Setup…
Device Select
You can use the [Reboot Module] button to force a reset of the unit, equivalent to a power-on reset.
You can use the [Restore Module] button to restore a module to its initial “out-of-box” configuration.
Ethernet Setup
You can use the [Get] button to retrieve the current Ethernet setup of the connected module (sometimes the Active
Values fields will indicate zeros and you must click [Get] to retrieve the actual active values).
You use the Ethernet Setup portion of the screen shown above to specify the network communication parameters
required to communicate with this module over Ethernet. You may have to consult with your network administrator to
complete the contents of this page. The parameter functions are defined below:
An IP Address is a unique identification number for any host (this module) on any TCP/IP network (including the internet).
The IP address is made up of four octets (8 bits), each octet having a value between 0-255 (00H-FFH). It is expressed here
in decimal form, with a period placed between octets.
The Subnet Mask is used to subdivide the host portion of the IP address into two or more subnets. The subnet mask will
flag the bits of the IP address that belong to the network address, and the remaining bits that correspond to the
host/node portion of the address. The unique subnet to which an IP address refers to is recovered by performing a
bitwise AND operation between the IP address and the mask itself, with the result being the sub-network address.
