NI 9205 with DSUB Isolation Voltages
Channel-to-channel None
Channel-to-earth ground
Continuous 60 V DC, Measurement Category I
Withstand
up to 2,000 m 1,000 V RMS, verified by a 5 s dielectric withstand test
up to 5,000 m 500 V RMS
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.
Caution
Do not connect the NI 9205 with DSUB to signals or use for
measurements within Measurement Categories II, III, or IV.
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.
Safety Guidelines for Hazardous Voltages
If hazardous voltages are connected to the device, take the following precautions. A
hazardous voltage is a voltage greater than 42.4 Vpk voltage or 60 VDC to earth
ground.
