Applications
GNP Computers produced embedded computing and industrial controller boards primarily for telecommunications, industrial automation, and process control applications from the 1990s into the 2000s. The NODE4U platform was a ruggedized, modular system used in environments requiring stable, dedicated alarm and I/O management — common in telecom equipment rooms, network infrastructure cabinets, and industrial control installations. The alarm card's role within such a system is to monitor system status signals and relay alarm conditions to an operator interface or external monitoring system via the DB9 serial port. This type of card is typically sought by organizations maintaining legacy NODE4U-based systems or looking for compatible spare parts for in-service equipment.
This GNP Computers NODE4U Alarm Card (1-503085, Rev X1) has been inspected and is in good condition. The PCB appears clean with no visible damage, broken traces, or missing components. The DB9 connector and internal header connector both look intact. There is light handling wear consistent with normal use. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
