Norcontrol Nn-791 I/o Processor Card

What is Norcontrol NN-791 I/O Processor Card?

The NN-791 is an input/output (I/O) processor card designed for use in Norcontrol’s marine automation platforms. It is an interface between field devices (e.g., sensors, switches, and actuators) and the central processing unit. In short, it aggregates data from onboard equipment and channels it into the vessel’s automation system for monitoring, analysis, and response.

A few technical highlights of the NN-791 are:

• Modular design for simple incorporation and swapping
• Several input/output channels to allow flexibility
• Interoperability with common maritime automation networks
• Quick signal processing for instant system updates
• Tough construction appropriate for harsh marine conditions
