The NI SCC-68 is a 68-pin terminal block engineered to streamline data acquisition system connectivity. It features integrated Signal Conditioning Circuitry (SCC) expansion slots that accept NI SCC modules, enabling direct signal conditioning at the point of connection. This design eliminates separate signal conditioning hardware, reduces cabling complexity, and improves signal integrity by conditioning signals closer to the source.
