Description
The Oceanic Systems 5972 is the 8 channel expansion module for the Oceanic Systems 5971 NMEA2000® Navigation Light Controller. The 5971 controls and monitors eight LED navigation lights on its own; plugging one 5972 into its right hand side on the same DIN rail takes the system to sixteen channels, and a second 5972 extends it to the maximum of twenty-four.
Every expansion channel gets the same protection and monitoring as the controller itself. A single calibration button lets the installer learn the current draw and wiring resistance of each LED circuit, so partial LED failures, corroded or high-resistance connections and open circuits are detected and alarmed. The system also logs the power-on hours of each lamp and warns once they pass 50,000 hours, so lamps can be replaced before their visible range falls short.
Each channel has a manual on/off/auto override switch for control if the network fails, a red/green status LED, a self-resetting fuse rated at 750 mA and a write-on label area to identify the light connected. LEDs connect to polarity-sensitive WAGO style cage clamp terminals along the lower edge of the unit. With a suitable NMEA2000® display such as Oceanic's Poseidon, the lights can be shown as a graphic mimic and switched from any screen, with OK/fault status and running hours for every lamp.
The 5971 and 5972 are designed and built in the United Kingdom to IEC60945, IEC61162-3 and the DNV navigation light controller standard. The 5972 is an expansion unit only and needs a 5971 controller to operate. It is supplied with the 5971/5972 Installation and Operation Manual.
