In practice this module lets an installer group navigation lights, bilge pumps, cabin lighting, washdown pumps and similar 12V accessories into a single compact enclosure that can be mounted close to the load bank, cutting down on long high-current wiring runs. Each of the 16 outputs reports real-time current draw back to the network, so a helm display can flag an overloaded or failed circuit instantly rather than the owner discovering a blown fuse days later. The 16 inputs allow physical switches, sensors or alarms elsewhere on the boat to be wired in and read digitally. As with the rest of the Garmin/EmpirBus digital-switching range, it is aimed at boat builders and refit yards standardising a vessel's electrical system on one digitally monitored architecture rather than at a single retrofit accessory.
