Notes about security
B design, the DAQ Series™ products are ver secure. The do not support terminal or file transfer
programs such as telnet, ftp, ssh, etc. This means that it is not possible for someone to ‘break in’ to this
module and access other devices on our local network. These products do not support remote
firmware updates which means that it is not possible for someone to remotel install malicious software.
The simplicit of this series of products makes them ver secure. As with an device to be installed on a
network, there are some securit precautions that should be observed. If this module is installed on the
Internet, it is recommended that passwords be enabled for the control page. Make sure secure
passwords are used. Passwords should be at least 8 characters in length and should be a combination
of upper case letters, lower case letters, and numbers. Don’t use passwords that would be eas to
guess. For additional securit , a firewall ma be used to limit access onl to selected IP addresses.
Another option ma be to set up a Virtual Private Network (VPN) between the network where the module
resides and the client machine (web browser, PLC, etc.).
Final installation note
This ControlB Web™ product supports connection to 10Mbps and 100Mbps networks. Although
100Mbps networks are faster, the amount of data transferred to and from this device is ver minimal and
little if an performance increase will be gained b setting it to 100Mbps. There are advantages
however, to operate this device at 10Mbps. At 10Mbps, less power is required, the unit runs cooler, and
the lifetime of the product will be extended.

Five-Input Module™ Users Manual 1.4 Example Configurations and Applications
.4.2 Five Input Module used with other ControlByWeb™ Products
This configuration is used to control devices remotel without a browser, or to extend a digital signal to a
remote location on the network. A control voltage applied to the input module controls the rela contacts
of WebRela -Quad™ (or other ControlB Web™ device) at a remote location. This configuration has
ma uses. It allows switches to be placed ver far awa from the devices that the control and sensors
to sound alarms at distant locations.
For securit applications, the switches in the example could be replaced with sensors, and the device to
be controlled could be a buzzers or chimes. A business owner, for example, could set up sensors at
his/her office and chimes at his/her home. The chimes at the home would announce each time the
sensors detects entr to the office (which ma be miles awa ). When the chime indicates office entr
late at night, the business owner can take appropriate action.
Another wa this configuration is useful is to extend the outputs of a PLC (Programmable Logic
Controller) in a factor to control motors and other devices in another building. The outputs of the PLC
are connected to the inputs of the input module and the motor and other devices to be controlled are
connected to the rela contacts of a WebRela -Quad™ (most likel using external rela s to switch the
loads). This allows an PLC to control devices across an IP network.

Section 2: Installation and Setup Five-Input Module™ Users Manual
2.2. Power Supply Connection
The input module requires power for its internal logic circuits. Connect appropriate power suppl to the
Vin+ and Vin- terminals. Alternativel , the input module units with the Power Over Ethernet option ma
be powered through the Ethernet connection instead of using an external power suppl .
Multiple input modules (and other ControlB Web™ products) ma be connected to a single power
suppl b connecting the power suppl input terminals in parallel. The power suppl must have a high
enough current rating to power all units connected (see specifications for current requirements for a
specific model number).
Five Input Module units with the Power Over Ethernet option ma be connected to an 802.3af compliant
Ethernet port instead of connecting an external power suppl . In this case, the input module is powered
through the network port. In 802.3af compliant networks, a 48 Volt power source is injected into the
Ethernet line. This power source is provided b an 802.3af compliant hub, switch, or power injector
which ma be located in a utilit closet which could be a distance awa from the input module. This
option is ver useful for installations where local power is not available. The power injector ma inject
the 48 Volt power source through the data lines or the spare lines in the Ethernet cable. DO NOT USE
A POWER INJECTOR THAT APPLIES A VOLTAGE TO BOTH THE DATA LINES AND THE SPARE
LINES.
2.2.2 Network Connection
Connect the Ethernet port to a 10 Base T or 10/100 Base T Ethernet connection. This t picall connects
to an Ethernet hub, switch, or router. For configuration, the input module ma be connected directl to
the Ethernet port on a computer using a “crossover” cable. Otherwise for connection through a hub or
router, a standard “straight-thru” cable should be used.
2.2.3 Optically-Isolated Input Connections
The opticall -isolated inputs can be used to monitor the state of digital signals, the can be used as
counters, or the can be used to control rela contacts in other ControlB Web™ products (for example
WebRela ™) over the network. Connect a DC signal voltage directl to the inputs. A current limiting
resistor is provided internall , so no external resistor is required as long as the maximum input voltage is
not exceeded. If an AC signal, or a signal greater than the maximum rated input voltage needs to be
connected to the input module, use a signal conditioner to convert the signal to the appropriate levels.
Several connection schemes are shown below.
This illustration shows a basic input connection. Here an automation controller with 5 volt or 24V outputs
is connected directl to an input.
Page 16 Xytronix Research & Design, Inc.

Five-Input Module™ Users Manual Section 2: Installation and Setup
The illustration below shows an input connected to a dr contact. In this case, the 5V output from the
input module is used to provide the voltage necessar to activate the input.
For applications where detection of 120VAC or 240VAC voltages is necessar , a simple DC power
suppl ma be used for signal conditioning. To do this, connect the input of the DC power suppl to the
120V or 240V signal and connect the output of the power suppl (+5V output) to the input of the Five
Input Module.
If an AC signal voltage needs to be detected, use a signal conditioner to convert the AC signal to a DC
voltage within the input range. An AC signal conditioner can be made using a diode (or bridge rectifier)
and a capacitor. Prepackaged signal converters are available as accessories at industrial automation
distributors. A simple voltage converter module (RedLion VCM10000 or VCM20000) is workable. These
are available in two input voltage ranges that cover the spectrum from 4-270VAC/DC. These devices
have a MOSFET output (solid state DC contact closure) which is compatible with the digital input. The
converter module accepts AC (50/60 Hz) or DC voltages with an input pulse rate up to 30 Hz. The
converter provides isolation between the input and output using an opto-isolator. You must provide a
voltage source for the converter circuit.
To connect a voltage to the input of WebRela ™ that is greater than the input is rated, a resistor of the
appropriate value and power rating can be used to reduce the voltage. The formula to calculate external
resistor values is provided below:
Each digital input is connected internall through a current-limiting resistor directl to a photo-coupler
circuit. The photo couplers are full isolated from each other. No external resistor is necessar as long
as the input signal is within the proper range (See Appendix: Specifications).
Xytronix Research & Design, Inc. Page 17

Section 2: Installation and Setup Five-Input Module™ Users Manual
The digital inputs each have an internal 3K ohm resistor. The forward voltage drop of the photo-coupler
is approximatel 1.2V and works well with an input current of 9mA. Use the following formula to
determine the resistor value needed for other voltage ranges:
R =((Vin-1.2)/0.009)-3000
Where:
•R = External resistor value required
•Vin = Desired input voltage
•1.2V = forward voltage drop of the LED in the photo coupler
•.009A = workable LED current
•3000 ohm = Internal resistor
For example:
To connect a 48VDC signal voltage:
R = ((48-1.2)/0.009)-3000 = 2200 ohms
Check the power dissipated b the resistor:
P = I x I x R, The resistor ust be at least .009 x .009 x 2200 = 0.18 Watts, so use a 1/2
Watt resistor.

Five-Input Module™ Users Manual Section 2: Installation and Setup
2.3 Establishing Communications for Setup
The Five Input Module is set up using a web browser. The first task is to establish communications
between a computer and the the input module so that the browser-based configuration can begin. To do
this, the computer and the input module must be ph sicall connected to the same network and both
must have IP addresses on the same network. There are two wa s to set up the computer and the input
module so that the are on the same network. The first wa (Option 1), is to change the IP address of
the input module to an address that is on the same network as the computer. The second wa (Option
2) is to change the IP address of the computer to an address that is on the same network that the input
module is set to b default.
2.3. Option : Assign a Temporary IP Address to the Input Module
This option is used to TEMPORARILY assign an IP address to the input module without the need to
change the IP address of the configuration computer. Note that the input module will onl use this IP
address as long as power is maintained. Once power is lost and restored, the input module will use the
IP address assigned in the setup page and not the temporar address assigned here. This means that
once communications are established, the desired IP address should be entered into the network setup
page using the browser.
To assign the temporary IP address...
1. Make sure the input module and the configuration computer are connected to the same physical
network. This will not work through routers or gateways.
