Web-i Relay Board 16-Channel 5-Amp DPDT with UXP Port

Use Any Device with a Browser

Control this Web Relay from anywhere you can get an internet connection and on any device with a web browser.  The Web-i interface built into this controller plugs in to a router on your network.  This tiny controller has built-in web pages, which give you access to the relays on the board.  These are working web pages that are ready to use or you can edit them with your favorite HTML editor.

Connectivity Options

Web-i controllers can be accessed remotely through an Internet connection using any device with an embedded web browser such as a smartphone, tablet, or computer.  The Module has firmware built-in that will allow you to access the web pages and that will send commands to the board. 

Web Relay Modules

This board is equipped with a Web-i Module.  The Module has custom firmware built-in that will allow you to access the built-in web pages.  Those pages will allow you to send commands to the board such as simple on/off commands or complex timing commands.  The Web-i communications module also adds an Ethernet interface to the board and will connect to a your router with a standard CAT-5 cable (a Wi-Fi adapter is available - see below).  The Web-i module will be powered by the board which will require 12 volts of power that can be hard wired or you can purchase a "wall wart" type Power Supply at checkout.  For more information on Web-i interface see Web-i Interface.  Lantronix XPort Pro Datasheet

Built-In Working Web Pages

The Web-i Module has built-in working web pages that will let you control the relays and read analog inputs.  You can also set passwords, create macros and send ProXR Commands all through pages that are already there!  These are working pages that are ready to go as soon as you establish communication to the board but it doesn't stop there.  Using a simple ftp program and HTLM editor you can download and modify the pages to fit your needs or company look including adding your logo and company information. 

LAN or Internet Control

Control relays from your local internet only when you are connected to your local area network or control from the internet from anywhere outside your network.  Once your router is properly configured for port forwarding, users may access the web pages built into the Web-i interface from anywhere in the world just like it were a normal web site. Simply use the Web-i web pages to monitor and control your electronics or customize the pages for your own needs.

Connectivity of Web Relays

Control these relays using the preferred web browser of your smart phone, tablet or computer. There are two main variations on communicating with the relays, Local Control and Global Control.

Local Control

Local control is the easiest way to gain access to your Web Relays. Local Control means your mobile and the Web-i relay controller are both connected on the same network in a local area. For instance, you are at work and your phone and Web-i device are connected to your office network using the same office router (which support Wi-Fi for your phone and Ethernet for the Web Relay controller).

Simply enter the IP address of the Web-i device into the URL bar of your favorite browser. You will have instant access to the web pages built in to the Web-i controller. When connected in this way, you will only have access to the relay controllers as long as your computer or mobile device is in range of your local area network.  Users outside the network will not be given access to the controller.  Global Control gets around this limitation.

Global Control

Global control means you can control a Web-i enabled relay controller from anywhere in the world.  This means your any device with a browser can access this board anywhere internet access is available.  Before you can communicate to a Web-i device globally, port forwarding must be configured on your router.

Port Forwarding

When using this board over the internet and outside the Local Area Network, Port Forwarding will be required.  Port Forwarding is a protocol used by your router to allow incoming requests for connections to get through to a specific device on a specific port.  Below is an example of how it works.  In this example a router has been setup to forward incoming requests for port 2101 to the device at the IP Address 192.168.2.19 on port 2101.  Now when any device that tries to access this Port on the External IP Address the router will see the request and automatically forward the request to the device at the IP Address of 192.168.2.19 on port 2101.  If this Port Forwarding rule was not in place and a request came in on port 2101 the router would not know which port or device to forward it to and the request for connection would be denied.  Note: Port Forwarding will not be necessary when using this within a Local Area Network.  For more on Port Forwarding with detailed instructions for every router visit: https://portforward.com/ .

Smart Phone Control

Once the Web-i web page appears on your smart phone, bookmark the page so you can access your relays just like an App on your home screen of your smart phone.  Using this method, you can be anywhere in the world and still monitor and control relays as long as your mobile device has an internet connection.  It even works using 3G and 4G internet services, so you can be in your car and stay in control of your relays.

Induction Suppression

Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer.  Controlling a inductive load using this relay controller requires the use of induction suppression capacitors.  The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay.  Without this capacitor, the lifespan of the relay will be greatly reduced.  Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly.  In the case of Ethernet devices, customers may experience loss of communications until the device is reconnected.  Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.

Built-In Web Pages

All Web-i boards have built-in web pages that can be accessed through any browser.  These pages are not on any internet site they are located in the Ethernet module installed on the board.  When you access the IP address of the board with any browser you will see these pages.  Below are screen shots of the working pages.  Using an FTP program the pages can be transferred from the module to your favorite html editor and modified, your logo or your customer's logo for example and more.

ProXR Relay

We've looked at the interface now let's take a look at the board design and programming.  The ProXR series controllers are manufactured by hand for a highly accurate and reliable design.  Equipped with the XR Expansion Port additional relays can be easily added.  Fully tested before they leave the production facility each ProXR controller is ready to stand up to rigorous demands from heat, cold or vibration.  The best test of all is the numerous boards in the field from customers all over the world in all sorts of conditions.  Take it from us, these controllers will hold up!

Easy Software Development

Most of our customers write their own program for controlling these devices. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language.  These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the device.

Plug-In for Visual Studio

The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line. The samples can be run in Visual Studio and full customization to your needs.  Over 40 samples included with this free download!  Component Library.

Base Station Software

Base Station will assist you in learning how this device functions and is the ultimate reference tool for setting up, testing and controlling this device.  Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software.  Base Station works by communicating with your controller to identify the model and provides the appropriate graphical user interface for setting up and testing the identified device.  To help you get started and learn this controller Quick Start Guides are available for just about every feature.  As you discover a feature in Base Station a link is provided where you can easily download the Quick Start Guide.

UXP Expansion

UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules.  If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. You will find the UXP port on models with UXP in the part number.

Summary of UXP Modules
• Compatible with UXP Series Controllers ONLY
• Not a stand-alone controller - MUST be used with a UXP Series Controller
• Add Contact Closure Inputs
   - up to 256 Inputs
• Add Analog to Digital Inputs
   - up to 48 Inputs
• AddDigital Potentiometer Outputs
   - up to 256 Outputs

UXP Expansion Modules

UXP Expansion Boards have no on-board brains.  They are entirely reliant on the brains of a "master" device.  A master device is an NCD controller with a UXP expansion port and a microprocessor of some kind.  Most master UXP devices have on-board relays.  If you need to add A/D, Contact Closure Inputs or Digital Potentiometers just plug in the appropriate expansion module.  You cannot daisy chain different types of modules to the same controller however.  In other words if you plug in a potentiometer you will not be able to plug a contact closure or A/D module also.  For controllers that are equipped with a UXP Expansion port (and are suitable master devices for UXP Series Expansion) simply look for UXP in the part number.  All UXP Expansion Modules have an input and an output so you can simply daisy chain the boards together until you reach the number of contacts you are looking for.

XR Expansion Port

Most UXP controllers (Master Devices) have an XR expansion port and therefore can accommodate XR Expansion Boards.  Typically the XR Expansion port is used to add relays to the main controller (Master Device).  Like the UXP Expansion boards the XR Expansion Boards have no on-board brains.  They are entirely reliant on the brains of a "master" device.  When you run out of relays, just plug in an XR expansion board that is equipped with the kind of relays you need.  You can add up to 256 relays including the relays that are on the main controller (Master Device). All XR Expansion modules are compatible with each other so if you want to add different types of relays you can.  For controllers that are equipped with an XR Expansion port (and are suitable master devices for XR Series Expansion Controllers) simply look for PROXR in the part number.

Using XR and UXP Together

If you select a board that is equipped with both XR and UXP port you can use both ports simultaneously.  This allows you to add and control more relays through the XR port plus add A/D, Contact Closures or Potentiometers to the same board through the UXP port.  This can all be controlled through the same virtual COM port on your computer.  These Expansion Boards can be purchase with the controller or purchased at a later time when you have a need to expand.  To use both ports together you will need to select a controller that has UXP and PROXR in the part number to have bothports available on the controller (Master Device).

ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set.  The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market.  The list of commands and parameters this board is capable of is extensive.  ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before!  For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.

Essential Power Requirements

Applying Good clean power to the board is essential for the operation of the board.  Not only for the switching of the relays but the firmware that processes the commands.  Without good steady clean power from a regulated power supply the board simply will not function correctly.  All boards on the site require 12 VDC power.  The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board.  The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector.  We also carry an international power supply with interchangeable adapters for international customers.

DPDT Relays Installed

This board has DPDT relays installed.  A single DPDT relay is made up of 2 SPDT switches.  Each relay acts as two switches that are activated at the same time.  This allows two independent signals to be switched at one time.  In effect, there are two independent switches on a single DPDT relay - they will always switch together.

There are two connectors with Normally Open, Normally Closed and Common for each relay allowing two separate connections.  The picture above shows the 4-channel connectors.  The diagram to the right shows the how the arms of the common connector swing from the Normally Closed to the Normally Open positions when energized.  Wiring to either the NO or NC can produce your desired results.

2-Million Cycles

ProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board.  With a 5-year warranty and a money back guarantee you have nothing to loose!  Place your order now, while everything is in front of you.

RoHS Compliant

This board is led free and RoHS Compliant.  If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.

Add Relays as Your Needs Grow

The ProXR series controllers are expandable up to 256 total relays.  The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay.  Expansion boards can be added until you reach 256 total relays.  The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.

16 User-Programmable Timers

The ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer.  The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications.  Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.

5-Year Warranty/Money Back Guarantee

ProXR Lite series controllers are guaranteed against manufacturing and functionality defects for a full 5 years!  Not to mention a 30-day money back guarantee!  If for any reason you are not happy with a relay purchased from Relay Pros, simply return it within 30 days and we will give you your money back!  Controllers that are damaged by our customers will not of course be warranted under any circumstances.
