Safety Voltage and Current
Notice
The protection provided by the PXIe-4143 can be impaired if it is used in a manner not described in the user documentation.
DC voltage
Range
±24 V
Continuous isolation, any pin to earth ground
60 VDC, CAT I
Transient overvoltage
1,000 V RMS, verified by a 5 s withstand
Caution
Do not connect the PXIe-4143 to signals or use for measurements within Measurement Categories II, III, or IV.
Attention
Ne connectez pas le PXIe-4143 à des signaux et ne l'utilisez pas pour effectuer des mesures dans les catégories de mesure II, III ou IV.
Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as
MAINS
voltage.
MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary
circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage
sources, and electronics.
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.
DC current range
±150 mA
