NI TB-2644B Terminal Block

Designed to support multiple configurations, the TB-2644B is a Terminal Block for the NI PXIe/PXI-2532B. This shielded Terminal Block enables you to configure your Switch Module as a 1-wire, dual 8 x 32 or 2-wire, 8 x 32 matrix. The NI TB-2644B can effectively connect signals to the Terminal Block through ribbon cable headers. This Terminal Block has an optional protection feature that protects the relays of the associated switch from capacitive loads.

In one configuration, the TB-2644B (Part Number: 782385-09) comes without protection resistors. However, part number 782385-10 can be utilized if you are interested in acquiring a Terminal Block with 100 Ohm protection resistance. This Terminal Block comes with 2 row headers and 2 column headers. For proper cabling and connectivity, it also has a screw-enforced strain-relief bar. The top cover of the NI TB-2644B is removable and must be removed when access to the connection headers is required.
