National Instruments PXIe-2531 PXI Matrix Switch Module
The PXIe‑2531 (Part Number: 780587-31) is a high-density, 512-Crosspoint, 1-Wire, PXI Matrix Switch Module from National Instruments. It has the capability to create up to a 4 x 2176 or an 8 x 1088 one-wire matrix in a single chassis. It is also compatible for larger configurations with multi-chassis solutions. This makes the NI PXIe-2531 ideal for high channel count automated test systems. The PXIe-2531 is comprised of compact reed relays. It has switching speeds up to 2,000 cycles per second. This feature enables the NI PXIe-2531 to synchronize with other instruments. The PXIe‑2531 is aimed for lowâ€current, high-speed switching.
The NI PXIe-2531 offers a high switching voltage from channel to channel, with values of 60 VDC and 30VAC RMS. It also has the same switching voltage capacity for the channel to the ground voltage. The PXIe-2531 Matrix Switch Module measures voltage category "CAT I or CAT 0". This module is designed for measuring voltages of specially protected secondary circuits. The NI PXIe 2531 has a high-class terminal block mounting on the front. This terminal helps provide the signal connection through VHDCI connectors for the matrix topology. This Matrix Switch Module uses an NI SHC68-68 shielded cable and has an NI TBX-68 screw terminal breakout. These features help connect signals to the rows and columns in the matrix.
NI Switch Executive is a smart switch management and routing tool for PXIe-2531. It helps to enhance productivity through interactive configuration. It can also improve test code reuse and system performance. This can be done by using switch programming with NI Test Stand, Lab VIEW, and Measurement Studio. NI Switch Executive makes switch system configuration simpler and boosts test performance.
