The latest version of the ProXR Series have interchangeable communications modules that can be swapped at will. Simply disconnect all power from the board and pull off one module and replace it with another.
Fusion 4 Series Controllers are the most powerful relay controllers we currently manufacture.
Capable of controlling relays from a computer, sensor readings, or a time schedule, Fusion 4
controllers can be used to automate just about any application. Choose a controller based on
the quantity and power rating of relays your application requires.
