Actisense Quick Network Block

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
