Maretron DCR100-01 Direct Current Relay Module

Description

Maretron Direct Current Relay Module – DCR100-01

Take control of high-current DC loads on your vessel with the Maretron DCR100-01 Direct Current Relay Module — a rugged, NMEA 2000®-integrated relay designed to automate and manage DC power circuits based on data, conditions, or logic from your marine network. 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.

The DCR100-01 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.

Whether you’re automating bilge pump activation based on sensor thresholds or integrating systems for smarter vessel management, the DCR100-01 enables flexible relay control without custom wiring harnesses or separate control panels.

Key Performance Features

• Six Independent Channels: Each module can control up to six separate DC circuits, such as lights, pumps, or fans, through the NMEA 2000 network.

• Solid-State Reliability: By using solid-state relays instead of mechanical ones, the DCR100 provides a longer lifespan, faster switching, and eliminates the risk of sparking in engine compartments.

• Current Monitoring: The module doesn’t just switch power; it also monitors the current draw of each individual branch circuit. This allows you to see exactly how much power a specific pump or light is using.

• Programmable Protection: Each channel can be programmed with a software-defined “breaker” trip point. If a circuit exceeds its limit, the DCR100 will automatically shut it down to protect your wiring.

• Network Integration: Fully compatible with Maretron N2KView and DSM-series displays, allowing you to create custom switching “pages” for your helm or remote monitoring.
