FCC Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that may cause undesired operation.
Warning: This equipment has been tested and found to comply with the limits for a Class B (Class A for POE
model) digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Installation Guidelines (Read efore Installing)
- Do not open the WebRelay-QuadTM enclosure. This will void the warranty.
- This unit must be installed by qualified personnel.
- This unit must not be installed directly outdoors.
- 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.
Notes about security:
By design, WebRelay-QuadTM is very secure. It does 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 WebRelay-QuadTM and access other devices on
your local network. WebRelay-QuadTM does not support remote firmware updates which means that it is not possible
for someone to remotely install malicious software. The simplicity of WebRelay-QuadTM makes it a very secure
device. As with any device to be installed on a network, there are some security precautions that should be observed.
If WebRelay-QuadTM 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 easy to guess.
For additional security, a firewall may be used to limit access only to selected IP addresses. Another option may be
to set up a Virtual Private Network (VPN) between the network where WebRelay-QuadTM resides and the client
machine (web browser, second WebRelay-QuadTM, etc.).
Final installation note. This ControlByWebTM product supports connection to 10Mbps and 100Mbps networks.
Although 100Mbps networks are faster, the amount of data transferred to and from this device is very minimal and
little if any performance increase will be gained by 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.

Revision 2.2b WebRelay-QuadTM Users Manual
Section 1: Introduction
WebRelay-QuadTM is a compact, four-relay module with a built in web server. It can be controlled and/or monitored
over any IP network including private networks, IP-based industrial control networks, and the Internet. Users can
operate WebRelay-QuadTM using a web browser or a custom application. Computers, PLCs, or automation controllers
may control and monitor WebRelay-QuadTM without user intervention. This works by sending text commands over
the network and reading XML status pages from WebRelay-QuadTM, or by using Modbus/TCP protocol.
WebRelay-QuadTM has many applications 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 computer. It can be used in
industrial applications to control motors, lights, coils, pumps, valves, etc.
1.1 Features
WebRelay-QuadTM is very simple but has many features. Some features include...
•No programming required
•Easy to use as a stand alone device or as part of a large control system
•Built-in web server provides simple, web based configuration and control
•Control page can be customized with appropriate text and buttons
•10/100 Ethernet connectivity
•Four, 24Volt 1-Amp relays
•Removable terminal connectors (included) simplifies wiring and service
•Custom applications can control WebRelay-QuadTM with simple text commands and read XML formatted
status.
•Modbus/TCP protocol support provides inter-interoperability with devices/software from other
manufacturers.
•Password protection
•Selectable TCP ports
•On/Off or pulse mode
•DIN-Rail or Wall Mount
1.2 WebRelay-QuadTM Models Available
WebRelay-QuadTM is currently available in three models. The only difference between the three models is the power
supply requirements.
Part Number Power Supply Requirements
X-WR-4R1-5 5VDC
X-WR-4R1-I 9-28VDC
X-WR-4R1-E Power Over Ethernet or 5VDC
1.3 Connectors & Indicators
WebRelay-QuadTM has a removable terminal connector and an Ethernet connector. The terminal connector is used to
provide power to the internal web server, and is used to connect external electrical loads to the relay contacts.
There are seven LED indicators on WebRelay-QuadTM. The Power LED (green) indicates that the unit is powered.
Four LEDs (green) labeled Relay 1-4 which indicate that the corresponding relay coil is energized. When the relay
coils are energized, the NO (Nornally Open) contacts are closed and the NC (Normally Closed) contacts are open.
The load device that is connected to the relay contacts may be on or off when the coil is energized depending on how
it is wired. The LINK (green) LED indicates that WebRelay-QuadTM is properly connected to an Ethernet network.
The ACK LED (amber) flashes when there is network activity. Note that the LINK and ACT LEDs are located on
the Ethernet connector.

1.4.1 asic Setup
The illustration below shows a simple WebRelay-QuadTM application. The example shows how a 3-color
industrial light tower can be controlled remotely over an Ethernet network. The three lights are connected to
three of the relays so each light can be controlled individually. The lights can be connected directly to the
relay contacts because they are low power lights (LEDs). The controller can be a web browser, a custom
control application running on a computer, a PLC, or an embedded industrial controller. Commands are sent
to WebRelay-QuadTM over the Ethernet network using standard IP protocols so the controller can be placed
physically next to the light tower or a distance away.

1.4.3 Using WebRelay-QuadTM Without a Computer
WebRelay-QuadTM can be used in conjunction with other ControlByWeb products such as WebRelayTM or
the Five- Input Module. This allows users to control devices at a remote location by using switches or
buttons instead of using a computer. The illustration below shows how three switches can remotely control
three indicator lights in a light tower at a remote location. This configuration offers many possibilities in
security and remote control. The inputs can be driven by switches, sensors, or digital outputs from a PLC or
automation controller.

Section 2: Installation and Setup
Installation consists of mounting WebRelay-QuadTM, connecting to an IP network, providing power, configuring via a
web browser, and wiring relay contacts to the device that will be controlled.
2.1 Mounting
WebRelay-QuadTM can be be wall mounted or DIN rail mounted. It should be mounted in a clean dry location where
it is protected from the elements. Ventilation is recommended for installations where ambient air temperature is
expected to be high.
2.1.1 Wall Mounting
WebRelay-QuadTM includes two keyholes in the rear of its enclosure for wall mounting. Mount to a wall by
using two #8 screws. Attach the screws to the wall vertically spaced exactly 2.5 inches apart. The head of
the screws should be about 1/10 inch away from the wall. See Appendix C for mechanical details.
2.1.2 DIN-Rail Mounting
WebRelay-QuadTM can be mounted to a standard (35mm by 7.55mm) DIN rail. Attach WebRelay-QuadTM 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. Remove WebRelay-QuadTM from DIN rail using a flat-head screwdriver. Insert the
screwdriver into the notch in the release tab and pry against the enclosure to release the bottom hook.
