1 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.
2 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.
3 Certain applications may require additional time for proper settling. Refer to the NI Switches Help for more information about including additional settling time.
4 Relays are field replaceable. Refer to the NI Switches Help for more information about replacing a failed relay.
5 The PXI-2568 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.
