National Instruments PXI-2529 PXI Matrix Switch Module

The National Instruments PXI-2529 (Part Number: 778739-01, 189397A-01, 189688B-01) is a high-density, 1-Wire, 128-Crosspoint PXI Matrix Switch Module that users can configure as either an 8x16 2-wire, 4x32, or 4 × 16 2-wire dual matrix by utilizing different NI terminal block accessories. This module comes equipped with electromechanical relays that offer remarkable performance for low thermal offset and high power-signals for precise measurements at low-voltage levels. The NI PXI-2529 features relay counting for deterministic operation and relay monitoring with hardware triggers to enhance test throughput. The device is equipped with a 100-pin HDI front panel connector.

This switch module is Measurement Category I rated and is designed to carry signal voltages under 150 Volts. However, it can withstand voltage surges up to 800 V. With this model, the user can achieve 30 W, 37.5 VA maximum switching power, 1 A maximum switching current, 2 A maximum carry current per channel, and up to 8 A maximum current as well. The NI PXI-2529 offers 150 V channel-to-channel and 150 V, CAT I channel-to-ground switching voltage. The device has a release time of 4 ms maximum at 20 °C, an expected mechanical relay life of 5 x 107 cycles, an electrical relay life of 5 x 105 cycles at 30 V, 100 mA, and 1 x 105 cycles at 30 V, 1 A.

This module features a 100-pin high-density interconnect (HDI) front panel connector. The relays it incorporates are latching electromechanical relays. As far as its physical characteristics are concerned, the NI PXI-2529 weighs around 410 g. The PXI-2529 is a one slot, 3U PXI module with PXIe compatibility with 21.6 × 2.0 × 13.0 cm dimensions. When used in a PXI chassis, this module consumes 65 W at 5 V and 2.5 W at 3.3 V. This module consumes 7.5 W at 12 V and 2.5 W at 3.3 V when used in PXI Express-based configuration. The device weighs 15 oz., and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 55 °C, a storage temperature range of -20 °C to 70 °C.
