The NI TB-2643 is a front-mounting terminal block for NI 2532 high-density matrix switches. In addition to defining an NI 2532 as a 4x64 matrix, the TB-2643 exposes signal connections through ribbon cable headers inside the housing. For high-power applications, you can include 100 Ω protection resistors in the configuration. To connect to the rows of additional NI 2532 switches, two sets of row connections are available in the terminal block.
