Description:

National Instruments BNC-2090A is a shielded, rack-mountable terminal block designed to simplify connections between your NI data acquisition (DAQ) hardware and your signal sources. With 22 BNC connectors and 28 spring terminals, this terminal block supports analog, digital, and timing signals, offering flexible interfacing with various I/O configurations. The unit is compatible with any 68-pin DAQ device from the M Series, S Series, E Series, or B Series.

This versatile adapter chassis provides silk-screened component areas for passive signal conditioning, enabling users to implement custom filtering or voltage dividers directly on the device. It supports multiple input configurations including differential (DIFF), non-referenced single-ended (NRSE), and referenced single-ended (RSE) modes, making it ideal for precision measurement setups in laboratories, field diagnostics, and production test environments.
