The NI 2810A/B (NI 2810) is a high-density matrix switch card for the NI SwitchBlock. The NI 2810 is designed for combination with other NI 2810 cards to create a customized NI SwitchBlock multicard device.

For certain applications, you may need to increase the default settling time. Refer to Adding Additional Settling Time for more information about when the additional time is needed.
Note   Reed relays are highly susceptible to damage caused by switching capacitive and inductive loads. Capacitive loads can cause high inrush currents while inductive loads can cause high flyback voltages. The addition of appropriate protection can greatly improve contact lifetime. For more information about adding protection circuitry to a capacitive load refer to Reed Relay Protection. For information about inductive loads refer to Protecting NI Switch Products when Switching Inductive Loads.
