National Instruments BNC-2142 Connector Block
The NI BNC-2142 (Part Number: 778021-01) is a Connector Block from National Instruments. This Connector Block is designed for the PCI-4453 and PCI-4454 Dynamic Signal Acquisition (DSA) devices. The BNC-2142 comes with four analog input connectors and two analog output connectors. Each input or output connector incorporated in this Connector Block is a BNC connector, designed for precision and minimum losses. This National Instruments signal conditioning accessory enables you to operate your PCI-4453 or PCI-4454 devices in single-ended mode.
The NI BNC-2142 is a simple, low-cost distribution Connector Block, which does not have any IEPE excitation provision. With this Connector Block, you can achieve single-ended mode operation on all six BNC connectors. This DSA accessory does not require an external power source to operate and can easily be connected to the upstream cards or systems through an SHC68-C68-A1 cable. By design, the PCI-445x devices can operate in differential ended input mode only. Thus, an accessory is required to operate these dynamic signal acquisition devices in single-ended mode. In this case, you can consider using the NI BNC-2142, a portable solution package in a high-grade plastic housing.
The design of this device makes it suitable for almost any application and environment. The BNC connectors utilized in this Connector Block can operate with unmatched precision and marginal signal losses, making the BNC-2142 an appropriate choice for analog communications. This connector block and the BNC-2140 come with a similar number of analog inputs and analog outputs. However, the BNC-2140 is considered for applications where IEPE excitation is required.
BNC-2142 Obsolete Status has been announced by National Instruments, but the Connector Block will still be available for purchase and repairs by Apex Waves.
