DESCRIPTION

The BCI 328 terminal block allows analog inputs acquisition and filtering before coding.

It has for each channel:

  • A protected input with ± 40V FS (G= 1)
  • An amplifier with programmable gains 1, 2, 4, 8
  • Levels of ± 10V FS to ± 1,25V FS
  • A low-pass filter of the 8th order Butterworth or Bessel following the configuration selected A standard conditioning of sensor accelerometer with integrated electronics (ICP)

The BCI 328 finds its interest in the following applications:

  • Anti alias filtering
  • Data acquisition systems
  • Medical electronic equipment and research
  • Aerospace, navigation and sonar applications
  • Sound and vibration testing / accoustic analysis, etc...
