X-11s™ Users Manual Introduction
Section 1: Introduction
The X-11s™ 2-relay expansion module is used in conjunction with the X- 00M™ controller. The X-11s
has two high-current relays. Both relays have Form-C contacts (SPDT). A rugged, high-current
connector provides connections to the relays. One or more X-11s expansion modules can be connected
to a X- 00M control module with a ribbon cable. The ribbon cable provides both power and
communications to the expansion modules.
The X- 00M is a multifunction web-enabled industrial I/O controller. It performs control, logic, and
monitoring functions similar to that of a Programmable Logic Controller (PLC). However, unlike a PLC,
the X- 00M is designed for web-based applications from the ground up. No add-on software or
hardware is required. The X- 00M can be fully configured, programmed and tested using its built-in web
server. The web setup pages are intuitive and easy to use and do not require special programming skills.
The X- 00M together with expansion modules such as the X-11s provide an easy, flexible and reliable
way to monitor and control systems and devices over a network. The X-11s is suitable for use with loads
which require line voltages and high current such as pumps, motors, lights and heaters.
1.1 Connectors & Indicators
Relays
The X-11s has two, high-current, line-voltage-rated relays. It has a large, -position plug-in screw
terminal connector that provides connections to the relays. The connector can be released by pushing
the two orange latches forward, then pulling on the connector housing while squeezing the latches.
Terminals are provided for the Common, Normally Open, and Normally Closed contacts. The connector
terminals are wired directly to the internal relays with no internal fuse or other over current protection.
The relays are isolated from all other circuits inside and from each other. When a relay coil is energized,
the NO (Normally Open) contact is closed and the NC (Normally Closed) contact is open. The load
device that is connected to the relay contacts may be on or off when the coil is energized depending on
which contacts are connected to the load.
Expansion us
The expansion bus allows for a family of expansion modules to be connected directly to the X- 00M
without the need for an Ethernet switch. The cable can be a daisy chain with multiple connectors. The

ribbon cable expansion bus provides both power and communications connections.
Power Supply
The expansion bus can provide up to 1.7 Amps for powering up to 32 expansion modules; however, the
maximum number of expansion modules depends on the module type and power source attached to the
X- 00M. The X-11s requires relative high current to operate the relays and the 1.7 Amp limit will be
reached before the 32-module limit.
The X-11s employs modern switch-mode power supply. With this type of power supply the current draw
decreases as the voltage increases; therefore, you can add more expansion modules by using a 24-volt
power supply than you can with a 12-volt power supply. See the X-600M User Manual for more details.
Indicators
The green, power LED indicator is illuminated whenever the module is powered. To identify the module
during installation, the X- 00M can send a blink command which will cause the power LED to blink for
three seconds. The two, yellow LEDs indicate the status of the relays - Each LED illuminates when its
respective relay coil is energized.

X-11s™ Users Manual Installation and Connections
Section 2: Installation and Connections
Installation consists of mounting the X-11s and connecting it to an X- 00M controller with a 10-conductor
ribbon cable. Programming and testing is done by using a web browser to configure the web pages,
inputs, and outputs for your specific needs.
2.1 Installation Guidelines
•This unit must be installed by qualified personnel. In the case of line-voltage connections, a
licensed electrician should be employed.
•This unit must not be installed in unprotected outdoor locations.
•This unit must not be used for medical, life saving purposes, or for any purpose where its failure
could cause serious injury or the loss of life.
•This unit must not be used in any way where its function or failure could cause significant loss or
property damage.
This equipment is tested to UL 1010-1 safety requirements for equipment to be supplied from the
building wiring (i.e. thru a circuit breaker). It is not rated for installation within or as part of the circuit
breaker panel. When used to control AC line voltages, the X-11s must be mounted and protected in a
suitable electrical enclosure.
2.2 Mounting
The X-11s can be mounted to a standard (35mm by 7.55mm) DIN-Rail. Normally expansion modules are
mounted to the left side (embossed logo side of the enclosure) of the X- 00M controller so that the
ribbon cable doesn't cover the power connector. The X-11s should be located in a clean, dry location
where it is protected from the elements. Ventilation is recommend for installations where high ambient
air temperatures are expected to be high. See Appendix D: Mechanical In ormation for additional
mechanical details.
2.2.1 DIN-Rail Mounting
Attach the X- 00M to the DIN-Rail by hooking the top hook on the back of the enclosure to the DIN-Rail
and then snap the bottom hook into place. To remove the X- 00M from the DIN-Rail, use a flat-head
screwdriver. Insert the screw driver into the notch in the release tab and pry against the enclosure to
release the bottom hook.

Installation and Connections X-11s™ Users Manual
2.3 Making Connections
CAUTION: Make sure the power is shut off before making connections
CAUTION: This unit should be installed by a qualified technician.
CAUTION: Miswiring or misconfiguration could cause permanent damage to the X-11s, the
equipment to which it is connected, or both.
2.3.1 Connecting the X-11s to the Expansion us
Connect the X-11s to the expansion bus using a ribbon cable (sold separately). The number of modules
that are connected to the expansion bus are dependent upon the type of module, the power supply
used, and the number and type of other modules connected to the expansion bus. This can be
calculated by adding up the total amount of current required for each module (with all relays, inputs, etc.
on) at the voltage provided by the power supply. That number is called the expansion bus current (make
sure the expansion bus current does not exceed 1.7 Amps). Next, add the expansion bus current to the
current required by the X- 00M. That is the total current required. Make sure the power supply used has
an output current rating that is higher than the total current required. Some extra margin is
recommended.
For example, using the 24V 1.75Amp power supply that we offer:
At 24V, the X- 00M draws 80mA which leaves 1. 7A for the expansion bus (1.75A - 0.080A =
1. 7A).
Each X-11s module requires up to 105mA at 24V. If we divide 1. 7A by 0.105A we get 15.9A.
This means … With a 24V, 1.75A power supply, the maximum number of X-11s expansion
modules that can be connected to the expansion bus is 15 (with no other types of expansion
modules connected).
Note: A larger power supply and power injectors can be used to attach more modules to the bus (see
the X-600M users manual or details).
2.3.2 Connecting Relays
A removable terminal connector is provided for making the power connections. The correct wiring
procedure is as follows:
1. Make sure power is turned off.
2. Remove the terminal connector from the X-11s and make wiring connections to the terminals.
This technique avoids stressing the internal components while torquing the screws.
3. Reconnect the terminal connector.
4. Apply power.
It is recommended that any load (device to be controlled) not be connected to the expansion modules
until after the X- 00M has been configured and tested. By doing this, wiring and configuration mistakes
will not cause the load device to turn on unexpectedly.
Make certain the wires are properly inserted into to the terminals and that the screws are tight.

Example Applications X-11s™ Users Manual
Section 3: Example Applications
3.1 Control a device over an IP network
The illustration below shows a simple example of how to use the X-11s to control a device over an IP
network. The device to be controlled is wired in series with the relay contacts.
Note: A use or circuit breaker is shown to limit current overload.
3.2 High Current Relay
The illustration below shows an example of how the X-11s is used to control an AC motor. A high-current
relay is used to switch the load current to the motor. In this example a MOV (Metal Oxide Varistor) is
used to help protect the relay contacts of the X-11s from arc damage. Under normal conditions the
resistance of the MOV is very high. When a spike or surge occurs the resistance of the MOV drops and
shunts the high voltage transients.

X-11s™ Users Manual Configuration and Setup
Section 4: Configuration and Setup
4.1 Setup Example
The Quick Start Demo
After making the power and Ethernet connections, the X- 00M can automatically scan for the presence
of any ControlByWeb™ Ethernet devices (on the same sub-net) and also for any expansion modules
connected to the X- 00M via the ribbon-cable connector. It also automatically creates a dashboard web
page and populates it with all of the resources (components) supported by the Ethernet devices and
expansion modules. This makes it easy to start experimenting with the web page's user interface and to
try out the relays and sensors.
To quickly add a device do the following:
1. Click on the Devices menu tab to pull up the Devices Overview page. Then click on the Find New
Devices button to scan the expansion bus and the local network for ControlByWeb devices and
expansion modules.
