Kongsberg's 5th generation MRU product line continues

Kongsberg’s product concept

Kongsberg understands that every operation on every ship is unique. To ensure that Kongsberg has the right technology solution for you, Kongsberg has developed a wide range of attitude sensors that provide unmatched performance for a variety of applications. This “product family” covers everything from units developed for dedicated applications to units that can be used for multiple applications on the same ship.

The blue MRU models (serial no’s 19000 and below) are now all obsolete and replaced by the following 5th generation MRU’s:
• MRU 5v
• MRU Hv
• MRU 3v (replacing MRU Z)
• MRU 2v
• MRU Dv
• MRU E

Junction Box
The now discontinued 4th generation MRU was supplied with the junction box JB1. The new 5th generation MRU is supplied with the junction box JB3.
A new 5th generation MRU can be connected directly to the older JB1, hence replacing the JB1 is not needed.
However, be aware that the COM2 and analog outputs will not be available with the JB1. In addition,configuration of the 5th generation MRU must be done through the service kit (MRU-T-Configkit-V).

Brackets
The new 5th generation MRU is compatible with all exisiting MRU mounting brackets from the 4th generation MRU’s.

Subsea Bottles
The 5th generation MRU is physically shorter than the 4th generation MRU. This means that you will not be able to fit a new MRU in an old subsea bottle, hence these will also have to be replaced.

Cables
Both generations of MRU’s have the same physical connector, hence cables do not directly need to be replaced. Note: As functionality/interface has changed between the two generations, please ensure that connections are referred to the 5th generation MRU.
Note:
• Analog signals are not available directly from the 5th generation MRU.
• Old subsea cables (MRU-E-CS4) are not compatible with the new 5th generation MRU when ethernet communication is used.
