The BNC-2110 is a shielded connector block that interfaces 68-pin M Series, S Series, and B Series DAQ devices to external instrumentation and sensors. It provides 15 BNC connectors for analog input, analog output, and user-defined signals, plus a 30-pin spring terminal block for digital I/O and counter/timer connections. The fully shielded metal enclosure minimizes noise and ensures signal integrity in laboratory, test, and production environments.
