DJB - CV1

DIN Rail Mounted Charge & Voltage Amplifiers/Filters

The CV1 DIN rail mounted range of Charge/Voltage/Filter nodules are available in a range of configurations to suit a variety of industrial and other applications where DIN rail mounting and screw connections are the preferred method of installation.

Providing all or a combination of Charge amplification, IEPE 4mA constant current supply and Fixed or Variable frequency filtering.

The modules utilize standard DIN rail mounts for fast fitting and set up, ideal for use alongside industrial cabinets or other wiring installations.

Modules available:

  • CV1-C : Charge amplifier
  • CV1-V : 4mA constant current supply for use with IEPE accelerometers and sensors
  • CV1-CF : Charge amplifier with fixed filter frequency
  • CV1-VF : 4mA constant current IEPE supply with fixed filter frequency
  • CV1-CVF : Charge amplifier with variable frequency filter
  • CV1-VVF : 4mA constant current IEPE supply with variable filter frequency

Frequency Options:

  • Fixed frequency version must be specified when purchased, available from 0.2Hz to 250kHz
  • Variable frequency version: 255 filter steps, set by DIP switch, range covering 0.2 Hz to 127.5kHz
    Both versions are available with a variety of filter types including, Butterworth, Bessel, Anti-aliasing or General Purpose with 24/48 dB/Octave cut off.
