The dedicated high-power output channels on this configuration make it suited to loads that draw more current than a standard output channel can safely handle — larger pumps, windlasses or winches — while the two communication outputs suggest support for driving accessory devices that need a data/control signal rather than a simple switched power feed. As with every DCM in Garmin's digital switching range, every output reports real-time current draw back to the network, letting a helm display flag an overloaded circuit or failed load immediately. This kind of mixed-output module is typically specified by a boat builder or refit yard planning a digital switching architecture around a specific vessel's known mix of standard and high-current accessories, rather than bought as a generic drop-in replacement for a single circuit.
