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 is
recommended with proper wiring practices. As a rule, I/O wires are normally separated from
power and network wiring for safety, as well as for low noise pickup.

Power Connections…
Note that you can use the bus power connector of the module to interconnect
modules by plugging them together and connecting them as a group to a suitable
power supply using an optional left or right terminal block, 1005-220 or 1005-221,
as shown below. You can even make I/O Excitation connections along the bus with
these connectors (see below, note that Excitation is isolated from DC power).
Important –End Stops: If this module uses the optionally powered (or redundantly
powered) via the DIN rail bus for hazardous location installations (Class I, Division 2
or ATEX Zone 2) it must use two end stops (Acromag 1027-222) to secure the
terminal block and module (not shown).
Excitation Connections
You must connect excitation to operate the outputs of this model. Outputs are the
drains of n-channel mosfet switches pulled-up to the excitation rail via 10KΩ
resistors and with their sources connected to RTN (all mosfet source leads are held
in common at Return). Connect DC excitation from 4-32V as shown in the drawing
of the next page. Observe proper polarity (excitation is reverse-polarity protected).
Optionally, excitation may be delivered (or redundantly delivered) via a DIN rail
connector (optional terminal required, see above). For excitation connections, use
14 AWG wire rated for at least 80°C. Do not exceed 36V DC peak.

Digital Input Connections
The sixteen inputs of this model are already wired to accomplish loopback
monitoring of the open-drain outputs and may alternately be used to monitor input
levels from the field if their tandem outputs are switched OFF. Inputs use active-
low TTL thresholds and accept voltage levels up to 32V. They additionally are pulled
up to Excitation via 10K pull-up resistors installed on-board. Observe proper
polarity when making I/O and Excitation connections. Refer to the following figures
to wire the active-low inputs of this model.
IMPORTANT: Do not allow unused I/O channels to float. This will occur if you
operate I/O without also connecting I/O Excitation, as the I/O channels each have
10KΩ pull-ups to the excitation rail. Likewise, failure to connect excitation would
allow channels to pull each other via their pull-up resistors.

Digital Output Connections
Sixteen smart open-drain (low-
side) N-channel mosfets that
switch the load to ground (return)
and include 10K pull-up resistors
to EXC.
You must connect Excitation to operate the outputs. Outputs will switch loads up to
32V and 250mA each. Note that since each output channel drain lead is pulled up
to excitation via a 10K pull-up resistor, one channel can pull on another channel if
the excitation rail is left floating. 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 4-32V to
operate outputs, do not
allow Excitation to float.
IMPORTANT –Add Protection with Inductive Loads: Outputs do include integrated 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. 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. The ground connections
noted are recommended for best results and help protect the unit by giving it a low
impedance path to ground for shunting destructive transient energy. See the
Electrical Connection 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 earth
grounds its USB port, making contact with both the USB signal and shield ground
which is 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, the Device/
Communication Setup page will appear. Once you select a
device and click “Open” to connect to an XT1112-000 or
XT1121-00, a screen similar to the following will appear:
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

TECHNICAL REFERENCE
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: You cannot operate the I/O channels of this model without
connecting excitation across the EXC & RTN terminals on the unit. I/O channels
are pulled up to the EXC rail with 10KΩ resistors and must not be allowed to
float. This model requires an excitation supply from 4-32V (52mA minimum).
The actual required current capability will depend on your loads and voltage
level. You can choose to connect to Excitation via terminals on the unit, or via
optional terminals that connect to the module’s bus connector along the DIN
rail (See Power and Excitation Connections). Outputs will not operate properly
if you do not connect Excitation.
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 connect to the module’s bus connector along the DIN
rail (See Power and Excitation 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 9 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 XT1112Config.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, XT1112-
000 with 16 sinking outputs, and XT1121-000 with 16 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 configured for network operation by initially connecting to USB and a host PC
running model-specific configuration software running under a Windows operating
system. This has the advantage of not having to know the modules set IP address,
or having to change the address setting of your network card to match its 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.
Note: Click [Open] only after a unit is fully powered-up and has established its network connection (after ~30 seconds
following power-up).
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 functions of these parameters 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.

Device/Communication Setup…
Gateway Address refers to the IP Address of the gateway this module is to cross, if your local area network happens to
be isolated or segmented by a gateway. Typically, it is assigned the first host address in the subnet address space. If a
gateway is not present, then this field should contain an unused address within the host subnet address range.
NOTE: In order to network your PC with an Acromag module, you may have to consult with your network administrator
and either temporarily change your TCP/IP configuration (see TCP/IP Properties of Network Configuration in Windows),
or create a separate private network using a second network adapter installed in your PC (recommended). The necessary
steps will vary with your operating system. Refer to Acromag Application Note 8500-734 to help accomplish this (located
on the CDROM shipped with your module or via download from our web site at www.acromag.com).
The DNS 1 Address refers to the IP address of the first Domain Name Server used on this network. A DNS server relates
symbolic address names to actual numeric IP addresses, while the DHCP server is responsible for dynamically passing out
IP addresses.
The DNS 2 Address refers to the IP address of the secondary Domain Name Server used on this network. A DNS server
relates symbolic address names to actual numeric IP addresses, while the DHCP server is responsible for dynamically
passing out IP addresses.
The Host Name is the name to be assigned to this host if its address happens to be assigned dynamically using DHCP.
The Addressing Method refers to how this network module will obtain its IP address when connected to its network.
Static addressing is exactly as the name implies—static and represents a unique fixed IP Address that is generally
assigned by your service provider or system administrator. The Default static IP address assigned to this module is
192.168.1.100 (refer to product side label).
DHCP (Dynamic Host Configuration Protocol) refers to a protocol for assigning dynamic IP addresses to devices on a
network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In
some systems, it can even change while it is still connected.
The Protocol addressing method refers to allowing the application protocol specific to this model (EtherNet/IP™) to set
the IP address (Profinet generally requires this).
By default, the module is setup to use Static IP Addressing and a default Static IP Address of 192.168.1.100. You can
optionally choose to have the IP address assigned dynamically via DHCP, but this will additionally require that you specify
a valid Host Name to retrieve the address from. Choosing Protocol gives the application protocol permission to assign
the address.
You can click the [Send] button to write your Ethernet Setup parameters to the unit once you are done making your
selections. This completes any changes made on this page.
The status field will indicate the status of your sent parameters over USB after clicking [Send]. The Network field will
indicate the current network connections status as well as the protocol used for this network. The Configuration field
will indicate whether the configuration is from an open device, or a default configuration.
You can click the [Exit] button in the lower right-hand part of this screen to exit the Configuration Software, or simply
click on another tab to access another page before exiting this software.
