The National Instruments PXI-2532B is a high-performance PXI Matrix Switch Module designed to accommodate high-density switching applications with up to 512 crosspoints. Optimized for flexibility, this 3U PXI module supports matrix configurations of up to 4×128 or 8×64 in a single unit, facilitating expansive automated test setups that require a significant number of connections. For users needing even larger matrix sizes, the PXI-2532B can be interconnected with multiple modules using the NI R1616 expansion link and compatible TB-264xB terminal blocks, allowing for configurations such as a 4×256 one-wire matrix.

Equipped with advanced compact reed relays, the PXI-2532B offers impressive switching speeds of up to 2,000 cycles per second, ensuring optimal throughput when synchronizing with other instrumentation. This module is capable of handling signals up to 100 VDC/100 Vp and 0.5 A, with a maximum switching power of 10 W per channel. It adheres to a channel-to-channel and channel-to-ground switching voltage rating of 100 V (CAT I), making it suitable for a variety of applications.

The PXI-2532B supports simultaneous operation of up to 40 relays with a mechanical relay lifespan rated at 1×10⁹ cycles. Electrical relay life may vary depending on the load conditions, ranging between 1×10⁷ cycles at 10 V, 100 mA, to 5×10⁵ cycles at 100 V, 10 mA. The module is equipped with two Samtec ERM8-EM series I/O connectors for high-density signal connections. With the capability to configure over 10 different matrix topologies through a range of terminal block accessories, the PXI-2532B stands out as a highly adaptable solution for managing numerous measurement and signal generation connections. The module weighs 1 lb (454 g) and measures 7.3 × 0.8 × 5.1 in (18.5 × 2.0 × 13.0 cm), making it an efficient addition to any PXI system. A three-year warranty and user manuals are available for download to assist in installation and maintenance. For pricing inquiries, please contact a National Instruments sales representative.
