    • 1 The maximum switching power is limited by the maximum switching current and the maximum voltage, and must not exceed 10 W.
    • 2 DC path resistance typically remains low for the life of the relay. At the end of relay life, the path resistance rapidly rises above 2 Ω. Load ratings apply to relays used within the specification before the end of relay life.
    • 3 Certain applications may require additional time for proper settling.
    • 4 Optional series protection resistance, available for the terminal blocks, increases the expected relay life at higher voltages. This series protection resistance shields the reed relays from the effects of cable and load capacitance. For more information, refer to the Reed Relay Protection tutorial.
    • 5 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.
    • 6 The relays used in the PXI-2532B are field replaceable.
    • 7 The PXI-2532B can recognize trigger pulse widths less than 150 ns if you disable digital filtering. Refer to the NI Switches Help for information about disabling digital filtering.
    • 8 NI advises against installing reed relay modules directly adjacent to an embedded controller with a magnetic hard drive because of the sensitivity of reed relays and the possibility of interference.
    • 9 Terminal block connectivity is with standard 0.050 inch pitch headers.
