NI TB-2651 Terminal Block
Designed to be used in industrial environments, the TB-2651 is a Terminal Block and switching accessory. This Terminal Block is compatible with the National Instruments NI-2531 (PXI-2531 and PXIe-2531). Through this accessory, users can achieve a single-wire, dual 8 x 32 matrix. The NI TB-2651 comes with various safety features, including strain reliefs and grounding lugs. This Terminal Block can be ordered through part number 781131-04.
The upper cover of this Terminal Block can be removed to access the inside screw terminals. The TB-2651 supports only one topology. However, you can go with another terminal block to configure the NI-2531 if you are looking for a different configuration. The installation of the NI TB-2651 requires a set of simple tools and an already configured NI-2531 (either PXIe or PXI based) plugged into a chassis. The TB-2651 Terminal Block can also be used in the construction and operation of multi-configuration switch modules.
