The NI PXI-2533 is configured as a 4x64 one-wire matrix and the NI PXI-2534 is configured as an 8x32 one-wire matrix. Because the modules use SSR technology, they offer unique benefits such as unlimited mechanical lifetime and the ability to route 55 V at 1 A on all channels simultaneously (unlimited simultaneous crosspoint connections). These features make the PXI-2533 and PXI-2534 ideal for routing general-purpose signals in highdensity matrix applications. Use these modules with the NI PXI-4110 programmable power supply and the NI PXI-4071 71⁄2-digit FlexDMM to build high-density automated test systems up to ±55 VDC/30 VAC and 1 A. The PXI-2533 and PXI-2534 maximize throughput in automated test applications through scanning. Scanning improves throughput by downloading a list of up to 32,000 connections to the switch and cycling through the list using an event (trigger) without any interruption from the host processor. Scanning is most efficiently accomplished by mating the PXI-2533 and PXI-2534 modules with an instrument, such as the PXI4071 71⁄2-digit FlexDMM, which issues a trigger after each measurement. Software All PXI switch modules from NI are shipped with NI-SWITCH, an IVI-compliant driver offering complete functionality for all switch modules. When programming high-channel-count switch modules such as the PXI-2533 and PXI-2534, switch management software like NI Switch Executive can help simplify programming. 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 using switch programming with NI TestStand test management software, the NI LabVIEW and LabWindows/CVI development environments, and NI Measurement Studio for Microsoft Visual Basic 6.0. Connectivity The PXI-2533 and PXI-2534 modules use a single 68-pin SCSI connector. You can connect signals to these modules using the NI SH68-68-S cable and the NI TBX-68 external terminal block.

Light from the encapsulated LED actuates the photo-sensitive MOSFET and allows current to flow through it. LED actuation provides a galvanic isolation barrier (no charge can flow) between the control circuitry and the MOSFET. This is analogous to the isolation barrier formed between the magnetic coil and the mechanical armature in electromechanical relays.

Solid-State Relay Construction There are two main advantages to using SSR technology in PXI: extended lifetime and unlimited simultaneous crosspoint connections. Because SSRs use solid-state devices (MOSFETS) to switch states instead of mechanical contacts, they have infinite mechanical lifetime. PXI switch modules that are based on SSR technology last longer and help reduce overhead in many applications by eliminating the need for frequent switching component replacement. Compared to electromechanical relays, SSRs require very little power to transition between ON and OFF states.This feature is especially useful when building PXI switch systems. The PXI backplane supplies limited power to each slot in the chassis. Most high-density electromechanical relay-based matrix modules require more power than that available from the backplane to close all crosspoints simultaneously. SSR-based matrix modules are not limited in the same way due to the low power consumption of SSR technology. The PXI-2533 and PXI-2534 256-crosspoint matrix modules are high-density switch products that incorporate SSR technology. Both modules offer unlimited mechanical lifetime and unlimited simultaneous crosspoint connections while providing the ability to switch up to 55 V at 1 A on all channels.
