This unit's own model code specifies a straightforward, symmetrical 16-in/16-out configuration, each channel rated at 18A -- a simpler, general-purpose I/O layout than Marvel's other listed DCM, which splits its outputs into standard, high-power, and negative-switched groups. That makes this variant well suited to a vessel's more evenly-loaded circuits -- cabin lighting, pumps, fans, accessory power -- rather than a mix of a few very heavy loads alongside many light ones. As with every DCM, it provides electronic fuse protection with programmable trip current, under-current fault detection, and soft start/stop, and reports real-time load and fault status back to the network for display on a compatible chartplotter. It's sold as the bare control module for professional installation into a vessel's DC distribution system during a build or refit, not a retail consumer accessory.
