National Instruments Corporation 782384-01 PXIe-2532B PXI Matrix Switch Module, 512-Crosspoint, Reed Relay, .5 A, 100 V

The NI PXI-2532B is a 512-crosspoint, high-speed matrix switch module. With the largest matrix size available in a 3U PXI slot, the NI PXI-2532B offers ultrahigh-density switch configurations in the PXI platform. With the ability to create up to a 4x2176 or 8x1088 one-wire matrix in a single chassis and even larger configurations with multichassis solutions, the NI PXI-2532B 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 NI PXI-2532B provides maximum throughput in a test system for signals up to 100 VDC/100 Vp or 0.5 A.

Connecting Signals to the NI PXI-2532B
You can choose from several accessory options for the NI PXI-2532B. To make any signal connection to this matrix switch module, you need to use an NI TB-264xB front-mounting terminal block. TB-264xB terminal blocks provide signal connections through ribbon cable headers. You can use an optional set of four column cables and one row cable to make these connections. If you prefer screw-terminal connections, you can use NI SCB-264x screw-terminal breakout accessories to connect to the other end of the ribbon cables coming out of an individual TB-264xB front-mounting terminal block.

Column Expansion Through Row Connections
If you need a matrix size larger than one of the standard NI PXI-2532B configurations, you can use the NI R1616 column expansion cable to interconnect the rows of two NI PXI-2532B modules via a TB-264xB terminal block. For instance, you can create a 4x256 one-wire matrix with two NI PXI-2532B modules, two TB-2640B terminal blocks, and one R1616 column expansion cable interconnected between the TB-2640B terminal blocks.

NI Switch Executive Switch Management Software
NI Switch Executive is an intelligent switch management and routing application. With NI Switch Executive, you gain increased development productivity by interactively configuring and naming switch modules, external connections, and signal routes. You also increase test code reuse and system performance by using switch programming with NI TestStand, LabVIEW, and Measurement Studio. Ultimately, NI Switch Executive simplifies switch system configuration and increases test performance, lowering your cost to test.

Optional Reed Relay Protection
Each NI 264XB terminal block accessory offers optional 100 Ohm protection resistors that extend the lifetime of your relays. See the "Reed Relay Protection" tutorial underneath the Resources tab for more information.
