Analog Measurement - Protection

16-bit AD conversion enabling continuous transient capture (no gain or AC/DC
switching required)

True simultaneous sampling of all 64 channels (no multiplexing)

Simultaneous sampling of different channels with different sampling rates

Frequency range: from DC to 10 kHz

Dynamic range: 90 dB

Signal to noise ratio: 90 dB

Cross-talk rejection: 100 dB

Accuracy amplitude: ±2% (Velocity 1 000 to 10 000 Hz, ±3%)
Typical accuracy amplitude < ±1% of API 670 defined full scale range.
Note : Filters ±0,5 dB in passband

Accuracy measurement type Other:
±1% for 0-10 VDC input
±2,9% for 4-20 mA input
Note : Accuracy ±1% (±2,9% for 4-20 mA) is only fulfilled if the complete 0-10 V or
complete 4-20 mA range is utilized to reflect the configured full scale.
