NI TB-2646B Terminal Block
Designed to support 2-Wire Dual or Single-Wire Quad 4 x 32 matrix topologies, the TB-2646B (Part Numbers: 153631-11L, 153631-12L, 782385-13, and 782385-14) is a Terminal Block. This Terminal Block can be used in a broad range of switching applications. The NI TB-2646B is specifically designed for the NI-2532B PXI or PXIe Switch Modules and cannot be used with any other Switch Module. This Terminal Block enables you to operate your switching device with a variable configuration. Through this Terminal Block, you will be able to route the signals to the switch through flexible ribbon cables.
The NI TB-2646B comes equipped with ribbon cable row and column headers. You can operate this Terminal Block with isolation resistors (optional component) to ensure the safety of the switch reed relays. A version of this Terminal Block with factory-installed isolation resistors is available (Part Number: 782385-14). The strain-relief bar provided in the TB-2646B Terminal Block keeps the cable held in its position in high vibration applications.
