NORCONTROL NN-791.10 I/O PROCESSOR CARD, HER 100261

This Norcontrol NN‑791.10 is a rack-mounted I/O processor PCB for Norcontrol marine engine room monitoring and automation system. The I/O processor card acts as the local rack processing unit, collects and executes digital & analog signal acquisition from the connected NA series I/O expansion cards. The I/O processor card processes field data from pressure, temperature, level sensors and limit switches, then communicates the processed values to the main system controller via dedicated marine bus network. The I/O processor card handles alarm judgment, limit value comparison and network management for the local automation rack. The I/O processor card uses conformal coated marine grade PCB to resist salt fog, vibration and temperature fluctuation inside vessel engine control cabinets. The I/O processor card has front panel LED indicators for power, network status and communication fault for on-site inspection and troubleshooting.

This module delivers local signal processing and network management for marine auxiliary machinery supervision. The NN-791.10 processor module supports hot-swappable Eurocard plug-in installation in Norcontrol automation racks. The NN-791.10 processor module manages the network of cascaded NA1003, NA1004 and other Norcontrol I/O cards. The NN-791.10 processor module performs fault diagnosis for each connected I/O channel and report fault to the main operator station. The NN-791.10 processor module meets marine classification requirements for commercial seagoing vessels.

It serves as a critical main processing spare component for Norcontrol marine automation system overhaul and retrofit. The Norcontrol NN-791.10 spare processor card is manufactured to original factory specifications for direct plug-in replacement.
