INPUT CARDS

12.8.2 GN3211 basic 20 kS/s input card

● 32 analog channels

● Balanced differential inputs

● ± 10 mV to ± 20 V input range

● Analog/digitalanti-aliaslters

● 20 kS/s sample rate

● 16 bit resolution

● Real-time cycle based calculators with triggering on calculated result

● Digital Event support

● Up to ± 10 kV input range using passive probe (option)

● Up to ± 1.2 kA input range using current clamp (option)

In differential mode, the card can be used in electrically noisy environ-

ments.TheCMRRofthetruedifferentialampliersensureshighsignal

delity.

When using the passive voltage probe and/or the current clamp options,

thecardcanbeusedasanentry-levelelectrical-inputampliertomea-

sure high voltages and currents.

Calibrating the probes and clamps with the channels and storing calibra-

tion results in the Perception Sensor Database can increase the accuracy

well above the accuracy rating of the probe or clamp.

In single-ended mode, the data acquisition card can serve as a cost effec-

tive input for preconditioned signals to be recorded with the GEN DAQ

series of products.

Superior, best in class anti-alias protection is achieved by a unique, multi

stageapproach.TherststagetheSigmaDeltaconverterwithbuilt-in

anti-aliasingltercreatesanaliasfreedigitaldatastreamatconstantrate

of 250 kS/s.
