Switch6 is a simple DMX relay card. Unlike the DMX relay cards that you can readily buy its relays are rated to 16A per channel, and the current is kept of the PCB through use of tab top relays. I’m going to build some of these cards into enclosures with socca out, to use as a proper relay backfeed for a AVO dimmer. You could use it for anything else that needs switching. It has a standard piano dipswitch for address setting.
