National Instruments PXI-2533 PXI Matrix Switch Module

Featured with Solid-State Relays (SSRs), the National Instruments PXI-2533 (Part Number: 778572-33) is a 1-Wire, 256-Crosspoint PXI Matrix Switch Module. The PXI-2533 is known for its reliability since its relays have an unlimited mechanical lifetime. This model offers ±55 VDC, 30 VACrms maximum switching voltage, 55 W maximum switching power, and 1 A maximum switching current. The module is designed to provide >2 GΩ, typical DC isolation resistance, 2 µV, typical, and 1 Ω (typical) total row-to-column path resistance.

 In a one row to one column, 50 Ω system, the NI PXI 2533 can provide >1.5 MHz (typical) single crosspoint bandwidth. The SSRs incorporated in this switch module have 724 µs (typical) and 2.5 ms (maximum) operating time. The NI PXI-2533 can scan at the rate of 400 crosspoints/s when switching at 1 Ampere and <20 V, with a simultaneous drive limit of 256 relays. This Matrix Switch Module can be triggered through PXI trigger lines <0 to 7> at a minimum pulse width of 70 ns and can generate output trigger signals at a programmable pulse width within a range of 1 µs to 62 µs.

For I/O connections, this model comes equipped with a 68-pin male SCSI type connector. The NI PXI-2533 consumes 8 W at 5 V, 1 W at 3.3 V in typical conditions. It is a 3U type, one slot PXI module and has physical dimensions of 21.6 × 2.0 × 13.0 cm. This module can be configured in a 1-wire 4 × 64 matrix topology.
