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.
