High-density two-pole PXI switching matrices feature relay self-test support

A range of high-density, two-pole PXI switching matrices has been launched by Pickering Interfaces. Series 40-580 (32×8) and 40-583 (64×4) matrices are supported by both of Pickering’s relay test tools (BIRST and eBIRST), delivering diagnostics for any relays that are approaching end-of-life or have been damaged by over-specification hot-switching events.

Featuring 256 2-pole crosspoints, these matrices use gold-plated contact electro-mechanical relays to switch up to 300VDC/250VAC and up to 60W maximum power; maximum current is 2A, hot or cold switching.

The integrated Birst self-test hardware helps find relay failures within each module. No test equipment is required – the user just needs to disconnect the front panel connector, launch the Birst application and the tool will run a diagnostic test that will find any relays with faulty contacts.

In addition, Pickering’s external eBirst tools will test out the front-panel connections as well as graphically identifying all faulty relays.

“Typical functional test applications for these new matrices include signal routing in ATE and data acquisition systems in sectors including automotive, aerospace, rail and industrial automation. Simple signal connections are via 78-pin D-type or 160-pin DIN connectors that are fully supported by our wide range of cable and connector accessories,” said Bob Stasonis, technical product specialist, Pickering Interfaces.

The single-slot 3U matrices can be used in any PXI or PXIe Hybrid chassis as well as in Pickering’s LXI and LXI/USB chassis, and driver support is supplied for a range of programming languages.

These new models complement the company’s established 40-582 (16×16) matrix and come with Pickering’s standard three-year warranty.

Pickering Interfaces designs and manufactures modular signal switching and simulation for use in electronic test and verification. The company offers a range of switching and simulation products for PXI, LXI, and PCI applications.

To support these products, Pickering provides cable and connector solutions, diagnostic test tools, along with application software and software drivers created by its in-house software team.
