Installation uidelines (Read Before Installing)
- This unit must be installed by qualified ersonnel.
- This unit must not be installed directly outdoors.
- This unit must not be used for medical, life saving ur oses, or for any ur ose where its failure could cause serious
injury or the loss of life.
Notes about security:
By design, WebRelay-10TM is very secure. It does not su ort terminal or file transfer rograms such as telnet, ft ,
ssh, etc. This means that it is not ossible for someone to ‘break in’ to WebRelay-10TM and access other devices on
your local network. WebRelay-10TM does not su ort remote firmware u dates which means that it is not ossible for
someone to remotely install malicious software. The sim licity of WebRelay-10TM makes it a very secure device. As
with any device to be installed on a network, there are some security recautions that should be observed. If
WebRelay-10TM is installed on the Internet, it is recommended that asswords be enabled for the control age. Make
sure secure asswords are used. Passwords should be at least 8 characters in length and should be a combination of
u er case letters, lower case letters, and numbers. Don’t use asswords that would be easy to guess. For additional
security, a firewall may be used to limit access only to selected IP addresses. Another o tion may be to set u a
Virtual Private Network (VPN) between the network where WebRelay-10TM resides and the client machine (web
browser, second WebRelay-10TM, etc.).
Final installation note. This ControlByWebTM roduct su orts connection to 10Mb s and 100Mb s networks.
Although 100Mb s networks are faster, the amount of data transferred to and from this device is very minimal and
little if any erformance increase will be gained by setting it to 100Mb s. There are advantages however, to o erate
this device at 10Mb s. At 10Mb s, less ower is required, the unit runs cooler, and the lifetime of the roduct will be
extended.

Revision 1.01 WebRelay-10TM Users Manual
Section 1: Introduction
WebRelay-10TM is a robust, ten-relay module with a built in web server. It can be controlled and/or monitored over
any IP network including rivate networks, IP-based industrial control networks, and the Internet. Users can o erate
WebRelay-10TM using a web browser or a custom a lication. Com uters, PLCs, or automation controllers may
control and monitor WebRelay-10TM without user intervention. This works by sending text commands over the
network and reading XML status ages from WebRelay-10TM, or by using Modbus/TCP rotocol.
WebRelay-10TM has many a lications and is only limited by imagination. It works very well as a stand-alone device
that can be controlled using a web browser or as a convenient way to add I/O to a com uter. It can be used in
industrial a lications to control motors, lights, coils, um s, valves, etc.

1.3 Connectors & Indicators
WebRelay-10TM has ¼ inch male tab connectors for ower and relay contacts, an Ethernet connector, and thirteen
LED indicators.
Two tab connectors located on the circuit board are used to a ly ower to the module. Each relay has three tab
connectors for direct connection to the relay contacts. All ten relays rovide common, normally o en, and normally
closed contacts. Female mating connectors (not included) are required for connection. The Ethernet connector is
located on a small CPU daughter card that is mounted to the main relay board.
Ten green LEDs indicate when each relay is energized. When the relay is energized, the common and normally o en
contacts are closed which allows current to flow through them (common and normally closed contacts are o en).
When the relay is not energized, the common and normally closed contacts are closed which allows current to flow
through them (common and normally o en contacts are o en). The LEDs are located close to the corres onding
relays. The ower LED indicator (green) is located on the small CPU daughter card. The Link LED (green)
indicates the Ethernet network is connected and ro erly linked. The Activity LED (amber) indicates network
activity is detected.

Revision 1.01 WebRelay-10TM Users Manual
Section 2: Installation and Setup
Installation consists of mounting WebRelay-10TM, connecting to an IP network, roviding ower, configuring via a
web browser, and wiring relay contacts to the device that will be controlled.
2.1 Mounting
WebRelay-10TM can be be mounted to a standard (35mm by 7.55mm) DIN rail. Attach the module to the DIN rail by
hooking the to hooks on the back of the PCB card to the DIN rail and then sna the bottom hooks into lace.
Remove from DIN rail using a flat-head screwdriver.
2.2 Connection
CAUTION: MAKE SURE POWER IS SHUT OFF BEFORE WIRING!
Connection to WebRelay-10TM is made through the ¼ inch male tab connectors. Mating connectors (¼ inch female
tab connectors) can be urchased at electrical su ly stores.
It is recommended that the load (device to be controlled) not be connected to WebRelay-10TM until after WebRelay-
10TM has been configured and tested. By doing this, wiring and configuration mistakes will not cause the load device
to turn on unex ectedly.
IMPORTANT: MAKE SURE WIRES ARE PROPERLY ATTACHED (CRIMPED) TO THE CONNECTORS,
AND THAT CONNECTORS ARE PROPERLY ATTACHED TO THE CIRCUIT BOARD!
2.2.1 Power Supply Connection
WebRelay-10TM requires ower for its internal logic circuits. Connect a 10-36VDC ower su ly to the
Vin+ and Gnd terminals. Note that a regulated ower su ly is recommended.
Multi le WebRelay-10TM units may be connected to a single ower su ly by connecting the ower
su ly in ut terminals in arallel. The ower su ly must have a high enough current rating to ower all
units connected (see s ecifications for current requirements for s ecific model number).
2.2.2 Network Connection
Connect the Ethernet ort to a 10 Base T or 10/100 Base T Ethernet connection. This ty ically connects to
an Ethernet hub, switch, or router. For configuration, WebRelay-10TM may be connected directly to the
Ethernet ort on a com uter using a “crossover” cable. Otherwise for connection through a hub or router, a
standard “straight-thru” cable should be used.

Revision 1.01 WebRelay-10TM Users Manual
2.2.3 Relay Connection
Direct connection to relay contacts is rovided through tab connectors located on the to of the relays. Do
not exceed s ecified load ratings for relay contacts (see s ecifications for load ratings).
2.3 Establishing Communications for Setup
WebRelay-10TM is set u using a web browser. The first task is to establish communications between a com uter and
the WebRelay-10TM device so that the browser-based configuration can begin. To do this, the com uter and
WebRelay-10TM must be hysically connected to the same network and both must have IP addresses on the same
network. There are two ways to set u the com uter and WebRelay-10TM so that they are on the same network. The
first way (O tion 1), is to change the IP address of WebRelay-10TM to an address that is on the same network as the
com uter. The second way (O tion 2) is to change the IP address of the com uter to an address that is on the same
network that WebRelay-10TM is set to by default.
2.3.1 Option 1: Assign a temporary IP address to WebRelay-10TM
This o tion is used to TEMPORARILY assign an IP address to WebRelay-10TM without the need to
change the IP address of the configuration com uter. Note that WebRelay-10TM will only use this IP
address as long as ower is maintained. Once ower is lost and restored, WebRelay-10TM will use the IP
address assigned in the setu age and not the tem orary address assigned here. This means that once
communications are established, the desired IP address should be entered into the network setu age using
the browser.
To assign the temporary IP address...
1. Make sure WebRelay-10TM and the configuration com uter are connected to the same hysical
network. This will not work through routers or gateways.
2. Assign the address as follows...
Windows :
O en a Command Prom t (on Windows XP, select START, then RUN, then ty e “cmd”).
Ty e...
arp -s {new IP address} {serial number of WebRelay-10TM }
Note: IP address format is: xxx.xxx.xxx.xxx
Serial number format is: ss-ss-ss-ss-ss-ss
For exam le, to set a WebRelay-10TM device (with serial number 00-0C-C8-01-00-01 ) to
10.10.10.40 the following command would be used.
arp -s 10.10.10.40 00-0c-c8-01-00-01
Next, ty e...
ping -l 10 {new IP address}
For exam le, if the new IP address is 10.10.10.40, the following command would be
used.

2.3.2 Option 2: Assign a temporary IP address to configuration computer
If the first o tion above is not used, you can use this o tion to communicate with WebRelay-10TM . By
default, WebRelay-10TM comes from the factory with an IP address of 192.168.1.2. Communications with
WebRelay-10TM may be established by assigning an IP address to the configuration com uter that is on
the same network as WebRelay-10TM (for exam le the configuration com uter could be assigned to
192.168.1.5) .
Instructions for changing the IP address of the com uter that will be used for WebRelay-10TM
configuration are given here. Note that these instructions are s ecifically for com uters with the Windows
XP o erating system. For setu using other o erating systems, refer to the a ro riate users manual.
