Switching & relays

Signal routing, multiplexing, and relay switching for the Accordion test system — modules that reconfigure the path between instruments and your DUT under software control. Every relay state and multiplexer selection is a channel; every routing change is a single API call.

The catalog covers analog multiplexers for sharing instruments across many test points, SPDT relays for switching higher-current paths, and DMM-style relay matrices for precise signal switching with galvanic isolation. Use multiplexers when you need to share a single source across channels; use relays when current rating, isolation, or contact behavior matters.
