24 Channel Latching Relay Controller Board

24 Relay Control Board

Powerful Command Set...Lots of Features

It is one thing to build a latching relay controller with a powerful command set and lots of features.  We have been doing that for years.  It becomes an entirely different breed of controller when the relay controller is capable of watching over your computer when things don't always go as planned.  All our 24 Channel Relay Controllers are part of the ProXR Serial line of controllers.  This means not only can will you find the Relay Controller that you need but it will have the ability to expand with your needs.

Latest Advancements

Look for our ProXR series controllers for the latest advancements in signal switching!  Available in USB Relay, 802.15.4 Wireless Relay and RS-232 Relay configurations, the ProXR Series is capable of controlling up to 256 relays.  Whether you need power switching or DPDT signal switching, the ProXR Series are built from the ground up with Expansion in mind.  Simply Chain the XR Expansion Modules, one after another, to meet your computer controlled switching requirements.
