National Instruments PXI-2530B

The National Instruments PXI-2530B is a high-density PXI multiplexer switch module designed for versatile high-speed measurement applications. With a capacity of 128 channels, this module features a scan rate of 900 cycles per second and is available in configurable options of 1-, 2-, or 4-wire connections. It supports multiple switching configurations, including eight banks of 16 x 1 (1-wire), 32 x 1 (4-wire), 64 x 1 (2-wire), or 128 x 1 (1-wire) multiplexer setups, as well as 4 x 16 (2-wire), 8 x 16 (1-wire), and 4 x 32 (1-wire) matrix configurations. The reed relays in the PXI-2530B can be replaced easily in the field, and users can monitor relay health through the optional NI Switch Health Center, enhancing reliability.

The PXI-2530B is designed to work seamlessly with high-speed measurement instruments like the National Instruments PXI-4070 6½-digit FlexDMM, supporting switching voltages of 60 VDC and 30 VACrms, with CAT I isolation guarantees. It features a robust front panel connector with a 160-position LFH matrix 50 format and is adept at handling a maximum current of 0.4 A per terminal and a maximum switching power of 10 W. The module operates within a PXI power requirement of 4.2 W at 5 V and 12 W at 3.3 V, delivering impressive bandwidths of over 19 MHz for 16 x 1 configurations and over 12 MHz for 128 x 1 configurations.

With a relay operate/release time of 555 µs and the capability to recognize pulse widths narrower than 150 ns with digital filtering disabled, the PXI-2530B is a highly capable switch module. Its physical dimensions are 8.5 x 0.8 x 5.1 inches, and it weighs approximately 9.4 ounces. The operational temperature range extends from 0 °C to 55 °C, while storage conditions allow for temperatures between -40 °C and 70 °C. This module comes with a three-year warranty, and users can access user and maintenance manuals available for download. For pricing information, please contact a sales representative.
