National Instruments PXI-2530 PXI Matrix Switch Module

Featured with three matrix and four multiplexer configurations, the National Instruments PXI-2530 (Part Number: 778660-01, 189291A-01) is a 128-Channel PXI Matrix Switch Module. This module offers up to 900 ch/s switching speed. The multiplexer configurations achievable with this model include: 32 x 1 (4-wire), 64 x 1 (2-wire), 128 x 1 (1-wire), etc. The matrix configurations possible are 4 x 16 (2-wire), 8 x 16 (1-wire), or 4 x 32 (1-wire). The device has a channel-to-channel maximum switching voltage of 60 VDC, 30 VACrms, CAT I, and a channel-to-ground maximum switching voltage of 60 VDC, 30 VACrms, CAT I. It has a maximum input current of 0.4 A per terminal, and a maximum switching input power of 10 W. The NI PXI-2530 is widely considered a viable front-end solution for high-speed measurement instruments like the PXI-4070 FlexDMM.

The reed relays incorporated have a mechanical life of 1 × 109 cycles and 555 μS relay operate/release time. With this Matrix Switch Module, the user can achieve >60 dB channel-to-channel isolation over a 200 kHz frequency band. To be utilized with the independent topology in any combination, the PXI-2530 offers eight interconnected banks of 16 x 1 (1-wire) multiplexers. To configure and program this module, the user can utilize the NI-SWITCH driver, which provides full functionality for every switch module. The NI PXI-2530 can also be used with the TB-2630, TB-2631, or TB-2632 Terminal Block to configure the Matrix Switch Module into different arrangements.

In any 50 Ω system and 1-wire configuration, this model can provide >15 and >3 MHz bandwidth while operating in 16 × 1 and 128 × 1 topologies respectively. For receiving trigger signals and to output trigger signals, the NI PXI-2530 can utilize either front panel or PXI trigger lines 0–7. The National Instruments PXI-2530 comes equipped with a 176-pin docking station plug front panel connector. The device has a recommended operating temperature of 0 °C to 55 °C. The device weighs 14 oz., and measures 8.5 x 0.8 x 5.1 in. in dimensions.

PXI-2530 Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
