Maretron RIM100 Run Indicator Module

The Maretron RIM100 Run Indicator Module is an essential diagnostic tool for any serious boater or vessel operator who demands real-time insight into their electrical systems. Whether you're monitoring engine status, pump operation, or critical onboard circuits, this NMEA 2000-networked module provides silent, continuous surveillance of both AC and DC electrical circuits across your boat's infrastructure. For anglers and cruisers who rely on dependable power management during extended trips, the RIM100 eliminates guesswork and keeps you informed of what's actually running—critical when every amp matters.

The RIM100 operates by monitoring whether an electrical circuit is energized and transmitting that status over your boat's NMEA 2000 backbone, integrating seamlessly with compatible chartplotters, display units, and marine electronics. The module works equally well for both manually controlled and automatically managed circuits, giving you flexibility across different onboard loads—from bilge pumps and galley appliances to engine auxiliary systems and navigation equipment. Its compact 7 x 5 x 10 inch footprint and lightweight 1.15 lb design make installation straightforward in engine compartments, cabin spaces, or panel mounts where space is at a premium.

Cruising sailors, liveaboards, and tournament anglers benefit most from the RIM100's ability to aggregate electrical status across multiple circuits on a single integrated display, reducing the need for separate indicator lights or manual checks. When paired with Maretron's wider marine network ecosystem, it enables centralized monitoring from your helm station or tablet, essential during rough conditions or when your attention is divided between steering and systems management. Installation requires connection to the monitored circuit and integration with your NMEA 2000 network—a straightforward process for anyone comfortable with marine electrical work or a professional installer.
