The Actisense Quick Network Block (QNB-1-PMW) allows backbone networking connections to be made easily and fault free on NMEA 2000 networks.
The QNB-1-PMW is a multi-drop network backbone connection block. It allows for two backbone connections (in and out) and a power entry point. There are up to six drops available, all fitted with standard NMEA 2000 female connectors which allow quick connections and provide the functionality of six backbone T-connectors.
The power entry connection is protected by two 4 Amp fuses, providing current protection to each half of the network backbone. Useful LED indicators show power status, detect a power reversal, indicate whether the fuses are still intact and detect the presence of data on the connected bus.
