Selecting a Web Relay Board

Below you will find all the 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.

Selecting a Web Relay Series

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.
