National Instruments Corporation 778572-31 NI PXI-2531 512-Crosspoint Matrix

The NI PXI-2531 is a 512-crosspoint, high-speed matrix switch module. With the ability to create up to a 4x2176 or an 8x1088 one-wire matrix in a single chassis and even larger configurations with multichassis solutions, the PXI-2531 is ideal for high-channel-count automated test configurations. Featuring compact reed relays with switching speeds up to 2,000 cycles/s and the ability to synchronize with instruments, the PXI-2531 is designed for the low-current, high-speed switching of signals up to 60 VDC/60 Vp.

Connecting Signals to the PXI-2531
Each matrix topology on the PXI-2531 has a unique front-mounting terminal block that provides signal connection through VHDCI connectors. Using an NI SHC68-68 shielded cable and an NI TBX-68 screw terminal breakout, you can connect your signals to the rows and columns of your matrix.

Column Expansion through Row Connections
If you need a matrix size larger than one of the standard PXI-2531 configurations, you can connect the rows of multiple PXI-2531 modules together. For instance, you can create a 4x256 one-wire matrix with two PXI-2531 modules, two TBX-68 screw terminal breakouts, and two SHC68-68 cables.
