Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.

Maximum current (switching or carry, per channel)

0.5 A

Caution The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 10 W.

Relay life (no load)

Mechanical

1 * 109 cycles, typical

Electrical (resistive, <10 pF load)

10 V, 100 mA

1 * 107 cycles, typical

20 V, 500 mA

5 * 106 cycles, typical

100 V, 10 mA

1 * 105 cycles, typical

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 resistive protection can greatly improve contact lifetime. For more information about adding protection circuitry to a capacitive load, visit ni.com/info and enter the Info Code relaylifetime. For information about inductive loads, enter the Info Code relayflyback.
Note The relays used in the PXIe-2531 are field replaceable.

Trigger Characteristics
