Technical Specifications

The NN-791.12 serves as a core processing unit within the legacy Nor Control DataChief and AutoChief maritime automation platforms. This I/O processor card is engineered to manage the high-speed acquisition of sensor data from engine room machinery and facilitate the execution of complex control logic for vessel maneuvering and alarm monitoring. With its robust PCB architecture (HEr100261I), the module provides stable data throughput and signal filtering, ensuring reliable operation of integrated ship control systems in demanding offshore and deep-sea environments.

Product Q&A

Q: Is the NN-791.12 compatible with modern Kongsberg K-Chief systems? A: The NN-791.12 is primarily a legacy component for older Nor Control generations. While it may communicate with newer systems via specific bridge interfaces, it is typically used as a direct replacement part for maintaining existing DataChief hardware.

Q: Does the HEr100261I revision support specific analog input types? A: This processor card is designed to handle a variety of I/O signals; however, the specific signal types (e.g., 4-20mA or PT100) often depend on the accompanying sub-modules or the system’s software configuration.
