Product catalog summary
Overview: The Maretron DCR100 is a Direct Current Relay Module featuring six DC relays, each capable of switching up to 10 amps. It connects to an NMEA 2000® network, allowing control via onboard devices or remotely through Maretron's N2KView® software. It supports both resistive and inductive DC loads and can switch AC circuits using external relays. The module also reports current through each channel to monitor electrical load status.
Key Features:
  • Six relays for on/off control over NMEA 2000® network.
  • Each relay supports up to 10 amps.
  • Individual relay electrical current monitoring.
  • Automatic relay overcurrent shutdown at approximately 12 amps.
  • Automatic relay thermal shutdown for over-temperature protection.
Specifications:
  • Operating Voltage: 9 to 32 Volts DC.
  • Power Consumption: 100 mA via NMEA 2000® interface.
  • Load Equivalence Number (LEN): 2.
  • Reverse Battery and Load Dump Protection included.
  • Maximum DC Switching Current: 10 amps per channel.
  • DC Switching Voltage: <32 VDC.
  • Contact Resistance: <10 mΩ.
  • Current Sense Accuracy: ±100 mA.
Environmental and Mechanical:
  • Size: 3.50” x 4.20” x 2.03” (including mounting flanges).
  • Weight: 13 oz. (368.5 g).
  • IEC 60945 Classification: Exposed, Degree of Protection: IP64.
  • Operating Temperature: -25°C to 55°C, Storage Temperature: -40°C to 70°C.
  • Relative Humidity: 93%RH @40°C.
  • Vibration and Solar Radiation tested per IEC standards.
  • Corrosion and Electromagnetic Emission/Immunity tested per IEC standards.
Certifications:
  • NMEA 2000 Level A.
  • Tested to IEC 60945 and IEC 61162-3 standards.
  • FCC and CE Mark for Electromagnetic Compatibility.

DCR100 Data Sheet -1

Maretron's DCR100 contains 6 Direct Current (DC) relays, each capable of switching up to 10 amps. The DCR100 connects directly to an NMEA 2000® network, so you can turn on and off the relays from any device onboard or remotely running Maretron's N2KView® software. The DCR100 easily handles resistive DC loads like lights, or inductive DC loads like pumps and motors. The DCR100 can also be used to switch AC circuits using external relays. An added benefit of the DCR100 is that it reports the current through each of the six channels. This allows you to determine if loads are drawing too little electrical current such as burnt out bulbs, or if the loads are starting to draw too much electrical current. Leading the way in NMEA open standards • Six Relays for On / Off Control Over • Each Relay Capable of Carrying Up to 10 amps • Individual Relay Electrical Current Monitoring • Automatic Relay Over Current Shutdown (Shuts Down at = 12 amps) • Automatic Relay Thermal Shutdown (Over Temperature Protection)
