National Instruments TB-2643 / TB2643 / 191981A-02 / 191981A02 Front-Mount 4x64 Matrix Terminal Block for NI 2532 Switches

•     Designed to easily facilitate column expansion with dual row connections
•     Optional configuration includes 100 Ω protection resistors on the rows and columns
•     Signal connections are made with ribbon cable headers inside the housing
•     Configures an NI 2532 as a 4x64 two-wire matrix

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 (not included). To connect to the rows of additional NI 2532 switches, two sets of row connections are available in the terminal block.
