Fault-free, NMEA 2000 backbone connections.

The Actisense Quick Network Block was developed to ease the connection of multiple NMEA 0183 or NMEA 2000 devices to a bus, and facilitate the powering and fusing of those devices from a common point. The Actisense QNB-1 and QNB-1-PMW provide flexible alternatives to multiple connectors reducing the cost of an NMEA 2000 cable installation.

Both QNB-1 versions are perfectly suited to areas of high instrument density, such as engine bays, as six network drops can be connected. The Actisense QNB-1 Quick Network Block 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. While the Actisense QNB-1-PMW Quick Network Block version is fitted with six standard NMEA 2000 M12 (Micro-fit) female connectors which allow 'plug and play' connections for quick and easy installation.

Actisense Quick Network Block Technical Features:
  • Wide battery input voltage range to offer maximum compatibility, the QNB-1 can operate from a battery supply anywhere between 8 and 35 volts
  • Eight x 5-way blocks of connectors, allowing up to 8 instruments to be powered and connected together at the same time
  • Data LED flashes as data passes through showing that network information flowing
  • Very low power consumption that is typically 10mA for the detector circuit and LEDs
  • Two fuses are provided (4 amps as standard) allowing each bank to provide a total of up to 4 amps of current
  • Very tough Polycarbonate case is certified to IP66 (classified as “totally protected against dust and protection against low pressure jets of water from all directions”)
  • Being Polycarbonate, it is also incredibly strong, offering a wide temperature range and superior protection to the electronics inside
  • The IP66 rating of the case is only limited by the sealing gasket strip, which can be enhanced by applying a suitable non-acid based marine sealant allowing use of the unit in areas where salt spray could enter, or in environments where maximum long-term reliability is paramount
  • Robust Nylon grommets are certified to IP68 (classified as immersible for long periods without water ingress)
  • Large range of possible cable diameters of between 4.5 mm and 12 mm, single or multi-pair wire types can be easily accepted
