NI TB-2640B Terminal Block
The TB-2640B (Part Numbers: 153636-01L, 153636-02L, 782385-01, and 782385-02) is a National Instruments Terminal Block that can be used to create a 1-wire, 4 x 128 matrix. This Terminal Block is designed for the NI-2532B Switch Module. The deployment of the TB-2640B requires a PXI or PXIe chassis with the NI-2532B Switch Module, a compatible cable kit, and a connector block (optional). 100 V and 60 VDC cable kits are available for this Switch Module. In addition, for matrix expansion, a row connection cable kit can also be acquired for the TB-2640B.
The SCB-264X is a screw terminal connector block that can be used if direct cabled connectivity between the DUT and the Switch Module is not possible. This Switch Module comes with four 34-pos column headers and two 16-pos row headers. The row and column headers incorporated in this Terminal Block are from the FTSH Series by Samtec. The NI TB-2640B weighs 0.73 lbs.
