Garmin DCM 12/24V 12V, In 16, Out 16, 18A, Rev. Pol, All output 0,5A minus
This listing is a Garmin digital control module (DCM) designed for dual 12V/24V marine electrical systems, used as a low-level relay/switching interface within a Garmin digital system installation such as a Force trolling motor deployment/stow mechanism or a wider digital switching setup connected to a Garmin chartplotter over NMEA 2000. The exact end application isn't stated in the catalog listing itself, so this description is limited to what the product's own name and part specification confirm rather than guessing which specific Garmin system it ships as a component of.
According to its own listed specification, the module operates on either 12V or 24V supply, provides 16 digital inputs and 16 digital outputs for monitoring and switching multiple circuits from a single unit, and is rated to handle 18A of current. It includes reverse-polarity protection to guard against wiring mistakes during installation, and each of its 16 outputs is rated for a minimum of 0.5A. Modules like this are typically installed inline between a boat's battery/fuse panel and its accessories (lighting, pumps, motor deployment actuators, or similar 12V/24V loads), letting a Garmin MFD or helm control unit switch and monitor those circuits digitally instead of through physical toggle switches. Installation should be carried out by a qualified marine electrician familiar with the specific Garmin system this module is paired with.
