Relay Control Over Web

The Web Relay is equipped with firmware built into the board that will allow you to Control relays with a web page. The web relay controllers have a web page built into the module that you can access through your local network or internet.

Control By Web!
The Web Relay is an ideal choice for applications that require you to control relays by the web, and it's extremely easy to work with since the working web pages are already in the module.  The board connects to your router with a standard CAT-5 cable where the router assigns it an IP address.  Simply access the IP address with any device with a browser and you can switch relays!

Web Relay Web-i ModuleBy selecting the Web Relay interface you will be sending commands through your local area network or internet to the board.  Boards on this page are equipped with a Web-i communications module that adds Ethernet communications to the board.  The board will plug directly into your router where it is assigned an IP address.  Once the IP address has been assigned you can access the pages built into the module and trigger relays.

Selecting a Web Relay Board

Below you will find the 2-channel Web Relay Controllers that are available. The difference being the amperage of the relays installed and the type of relay.  Choose the controller that fits the amperage you are switching.  You will find SPDT relays in the 5, 10 and 20 amp versions and an SPST version in the 30 amp version.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
