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 sophisticated and thorough 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 provides a quick and simple way of finding relay failures within each module. No test equipment is required; simply 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 test tools will additionally test out the front-panel connections as well as simplifying fault-finding by graphically identifying all faulty relays.

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