Hi there, FES makes a high-current relay module. But during the development of the final version, we made a run of prototype boards that it turns out we won't be using. We moved the input header location so that we can use the injection molded case for more products (and injection molds aren't cheap). Anyway, we've bundled up the boards and all the componenets needed for the DIY crowd. You can save some money if you're handy with a soldering iron.

While the module was designed to work with the ProShift I/O, it can be used to manually control (or via key control) up to four fused circuits.

Here's a photo of the completed board:

Each channel has an indicator LED to show if it's active. The PCB is 54mm x 56mm, or just over 2 inches on a side. The price is $35 for the kit (final version with case and base is $79.95) and can be ordered here. When these are gone, they're gone and the DIY kit will go away.

Thanks for looking!
