QNB-1 - NMEA 0183 / NMEA 2000 Quick Network Block

The QNB-1 is perfectly suited to areas of high instrument density, such as engine bays, as six network drops can be connected.

The QNB-1 can limit the current to the safe level for the network. The LEDs provide information for the installer during set up and use to indicate the presence of data, power status, power reversal and to show whether the fuses are intact.

Benefits of the QNB-1 versions:

• One unit provides six NMEA 2000 drops
• Power hook up is protected
• Simple installation on Mini and Micro networks
