Navigation Light Controller 8 channel expansion module

The Oceanic Systems 5972 is an 8 channel expansion module for the 5971 Navigation Light Controller. Adding one 5972 takes the system from eight to sixteen controlled and monitored LED navigation lights, and a second module extends it to twenty-four. Like the controller, each expansion circuit continuously checks LED and wiring integrity and tracks LED power-on hours, so failures are detected and lamps can be replaced before their visible range is affected. Each channel has a manual on/off override, local red and green status indicators and a self-resetting safety fuse, and a full mimic can be shown on any Poseidon screen. The module is standard DIN rail mounted with WAGO style cage clamp connections and is designed to IEC60945.
