NI CB-50LP Input / Output Connector Block

The NI CB-50LP is an input/output connector block that translates 50-pin male IDC connectors from National Instruments DAQ devices into 50 individual screw terminals. This termination accessory simplifies field signal connectivity and wiring management for data acquisition systems. The unshielded design requires consideration of EMI exposure in noise-sensitive environments.
