Web Relay 2-Channel 30-Amp ProXR Lite

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 Lite Relay

In this tab we'll take a look at the board design itself.  The ProXR Lite series controllers are machine manufactured for a highly accurate and reliable design.  Fully tested before they leave the production facility each ProXR Lite 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!

Not Expandable

Unlike it's big brother, the ProXR Series, the ProXR Lite series controllers are NOT expandable. The firmware still thinks 256 relays are available but the relay portion of the controller only responds to the first 1, 2, 4 or 8 relays in Bank 1.

Full ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set - it's just not expandable.  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.

Read Analog Sensors

We did NOT skip the Analog Input portion of the ProXR Lite.  All ProXR Lite controllers offer a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control.  Read and control from 8 sensors per board from 0 to 5 volts!  A/D inputs are ideal for reading the on/off status of switches.  Simply position the Up/Down jumper in the UP Position and connect a switch between input and ground, software may then be used to monitor the contact closure status of your switch.  AD inputs can also be used for reading variable resistance signals.  Position of Up/Down jumper should also be in UP position for reading variable resistance signals. The board will then will return a value between 0-255.

SPST Relay Installed

This device has SPST relays installed.  SPST Single Pole Single Throw Relays simply connect two wires together.  The Common (COM) is the  moving part of the relay that comes in contact with the Normally Open (NO) when the coil to the relay is energized.  Wiring is done directly to the Relay terminals using a common 1/4" quick disconnect terminal.  To the left is a picture of the connector that will connect to the relay.

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.

Break-A-Way Tabs for a Smaller Design

The ProXR Lite relays have a great feature where space is a premium - Break-A-Way Tabs. The Break-A-Way Tabs allow most boards to fit in an optional undrilled plastic enclosure.  Snap off the Break-A-Way Tabs and you have a controller with a smaller profile when you need to fit in a tight space.
