Input Cards for 32 Channels: GN3210/GN3211

Providing different operational modes, these input cards adapt to your needs:

In differential mode, the GN3211 and GN3210 input cards can be used in electrically noisy environments. The CMRR of the true differential amplifiers ensures high signal fidelity. When using the passive voltage probe and/or the current clamp options, the card can be used as an entry-level electrical-input amplifier to measure high voltages and currents. Calibrating the probes and clamps with the channels and storing calibration 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 GN3211 and GN3210 input cards can serve as a cost-effective input for preconditioned signals to be recorded with the GEN DAQ series of products.

In addition to that, the GN3210 input card offers two more operational modes:

In IEPE mode, the GN3210 input card offers an excellent price/ performance ratio for an array of IEPE based sensors (accelerometers, microphones, etc.). The high dynamic range of the amplifier and the 24-bit A/D converter as well as the excellent band-pass flatness up to a 100 kHz bandwidth ensure phase alignment and accurate amplitude measurements.

In Charge mode, the GN3210 input card can be used directly with charge type sensors, such as piezoelectric accelerometers or pressure transducers.
