Ideal for advanced power management, this compact relay module allows onboard systems, sensor inputs, or configurable triggers from your NMEA 2000® network to control individual DC circuits such as pumps, lighting, fans, horns, or other high-current devices with precision and safety.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eDCR100-01\u003c\/strong\u003e connects directly to your NMEA 2000® backbone, enabling other Maretron devices, software, or data sources to trigger relay actions without the need for separate wiring logic controllers. Its sealed marine-grade housing, corrosion-resistant terminals, and robust DC relay design ensure long life and dependable operation in harsh saltwater and vibration-prone environments.\u003c\/p\u003e\n\u003cp\u003eWhether you’re automating bilge pump activation based on sensor thresholds or integrating systems for smarter vessel management, the DCR100-01 enables
