Description

KONGSBERG NN791.10 CPU 5MHZ I/O Processor Card – K-Chief / SDP Automation Series

When a vessel’s integrated automation system loses its central I/O processing capability, the consequences cascade instantly — alarm management fails, sensor data stops flowing, and operators are left blind to critical machinery states. Engine rooms go unmonitored, safety interlocks become unreliable, and the risk of unplanned downtime or regulatory non-compliance rises sharply. The KONGSBERG NN791.10 CPU 5MHZ I/O Processor Card is the precision-engineered heart that prevents this scenario, keeping your automation backbone running without interruption.

The NN791.10 occupies a pivotal position within KONGSBERG’s K-Chief and SDP (Ship Data Processing) automation platform — one of the most widely deployed integrated automation systems in the global maritime industry. Operating at a 5 MHz clock speed, this CPU card handles real-time I/O processing tasks that demand deterministic response times and high reliability in harsh marine environments. KONGSBERG automation systems are installed on thousands of vessels worldwide, from offshore supply vessels to LNG carriers, making genuine spare parts like the NN791.10 mission-critical assets for fleet operators and ship managers.
