The NI SCB-100 is a shielded I/O connector block for National Instruments data acquisition devices equipped with 100-pin connectors. It provides low-noise signal termination through 100 screw terminals, supporting Digital I/O, Counter/Timer, and Multifunction I/O modules. The SCB-100A variant is recommended for new designs with DIO and TIO applications.
