NI PXI-2530
The NI PXI-2530 is a high-density multiplexer/matrix switch module for the PXI platform. The NI PXI-2530 uses reed relays.
A number of factors can affect the life expectancy of reed relays. Refer to Reed Relay Protection for information about protecting the reed relays on the NI PXI-2530.
Refer to Signal Connections for pinouts for each topology.
