FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the PXI-2586 a relay module or a multiplexer?

NI identifies it as a general-purpose switch with 10 independent SPST (Form A) relays, rather than a dedicated multiplexer.

Can the PXI-2586 be used for fault insertion?

Yes. NI documents externally wired configurations including a three-channel fault-insertion unit with two fault buses using one PXI-2586. These configurations require external connections between channel and COM pins.

Where are the relay names for software control documented?

NI directs users to NI Switches Help under Devices, the device model, and Hardware Diagram for relay names used with NI-SWITCH relay-control functions.
