    • 1 Switching inductive loads (for example, motors and solenoids) can produce high voltage transients in excess of the module’s rated voltage. Without additional protection, these transients can interfere with module operation and impact relay life. For more information about transient suppression, visit ni.com/info and enter the Info Code relayflyback.
    • 2 The switching power is limited by the maximum switching current and the maximum voltage.
    • 3 Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance may rise rapidly above 1 Ω.
    • 4 Certain applications may require additional time for proper settling. Refer to the NI Switches Help for more information about including additional settling time.
    • 5 Relays are field replaceable. Refer to the NI Switches Help for more information about replacing a failed relay.
    • 6 The PXI-2576 can recognize trigger pulse widths less than 150 ns if you disable digital filtering. For information about disabling digital filtering, refer to the NI Switches Help.
