Selecting The Web Interface

By 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 4-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.  DPDT versions are also available with 1, 3 or 5 amp relays installed.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.

Selecting a Web Relay Series

The Web Relay boards are available in the ProXR Lite and ProXR versions. Both versions have the same firmware installed and accept the same ProXR command set, the industry leading command set for controlling relays.  The ProXR lite version is non-expandable, the ProXR version is expandable to 256 relays.  When you find your controller click on the Full Description link to view full specs, watch setup videos, download software and purchase.
