NI SCXI-1130
The NI SCXI-1130 is a high-density multiplexer/matrix switch module for the SCXI platform. The NI SCXI-1130 uses reed relays. The NI SCXI-1130 does not support routing signals to the high-voltage analog bus.
A number of factors can affect the life expectancy of reed relays. Refer to Reed Relay Protection for information about protecting the reed relays of the NI SCXI-1130.
