NORCONTROL
NN-824
ANALOG TO DIGITAL CONVERTER PCB CARD
HE-220283B
EM: A820
94V0 10.92
The Norcontrol NN-824 is an analog to digital converter PCB card, designed to interface analog signal inputs with digital processing systems within marine control and automation environments. Referenced under part number HE-220283B and associated with the A820 equipment module designation, this card performs the critical function of translating continuous analog signals — such as those from sensors and transducers — into digital data that can be processed by the vessel’s control and monitoring infrastructure. As a component within the Marine Control System category, it supports the reliable operation of onboard automation where accurate signal conversion directly affects safety and system performance.
Key Features
✓ Performs analog to digital signal conversion, enabling precise interfacing between field sensors and digital control processing systems.
✓ Carries the 94V0 flame retardancy rating on the PCB substrate, indicating compliance with standard flammability requirements for electronic assemblies.
✓ Designed for integration within Norcontrol control system architectures, compatible with configurations referencing the A820 equipment module designation — specific system compatibility subject to confirmation.
✓ Suitable for installation within protected, dry control panel enclosures typical of machinery control rooms and integrated automation cabinet assemblies onboard vessels.
✓ Serves as a direct replacement card for maintaining signal integrity within existing Norcontrol automation systems, supporting scheduled maintenance and fault rectification programmes.
Marine Applications
✓ Integrated automation and control systems aboard merchant vessels, including bulk carriers, tankers, and container ships requiring continuous sensor signal processing.
✓ Machinery control room panels where analog sensor outputs from engines, pumps, and auxiliary systems require conversion for digital monitoring and alarm functions.
✓ Offshore support vessels and platform supply vessels utilising Norcontrol-based automation for dynamic positioning and machinery management systems.
✓ Naval and government vessels employing centralised control architectures dependent on stable PCB-level signal conversion components.
✓ Vessel upgrade and refurbishment projects where obsolete or faulty analog to digital converter cards require like-for-like replacement to restore full system functionality.
Why Marine Engineers Choose
Marine engineers and vessel operators select the Norcontrol NN-824 PCB card because it maintains the signal conversion accuracy that automation and alarm monitoring systems depend upon, ensuring consistent data integrity across onboard control networks without requiring broader system modifications.
Ideal For
Merchant fleet operators, offshore vessel managers, naval procurement teams, and ship management companies maintaining vessels equipped with Norcontrol marine control and automation systems.
