National Instruments BNC-2142

The National Instruments BNC-2142 Connector Block, with part number 778021-01, is a specialized accessory designed for use with the PCI-4453 and PCI-4454 Dynamic Signal Acquisition (DSA) devices. It features four BNC connectors for analog input and two BNC connectors for analog output, allowing for precise signal conditioning with minimal losses. The BNC-2142 enables single-ended operation across all six connectors and does not require an external power source, ensuring easy integration into your existing setup via an SHC68-C68-A1 cable. Although the PCI-445x devices typically operate in differential input mode, the BNC-2142 offers a convenient and cost-effective solution for those needing single-ended capabilities without IEPE excitation. Housed in durable plastic, this compact connector block is suitable for a variety of applications and environments. It is worth noting that the BNC-2142 is considered obsolete by National Instruments; however, it remains available for purchase and repair through Apex Waves.
