Realtime I/O for rough conditions

AVL Data Acquisition with F-FEM/F-FEM SNAP-IN

Test beds in the automotive industry are relatively rough environments where I/O systems are subjected to heat, vibration, fumes and EM radiation. The AVL FEMs have been designed specifically for this environment.

AVL Approach

Depending on the measurement application different
F-FEM modules are available.

AVL F-FEM 19" *)

F-FEM-AIN, F-FEM-AIS

16 channels for the measurement of voltages, currents, temperatures, resistances and measuring bridges.

F-FEM-AIS HV

16 channels for the measurement of voltages, currents, temperatures, resistances and measuring bridges on high voltage potential (+/- 1000V DC).

F-FEM-AIT

32 channels for the measurement of temperatures and low voltages.

F-FEM-AIF

16 channels for the measurement of voltages and currents.

F-FEM-AIF HV

16 channels for the measurement of high voltages (+/- 1000V DC).

F-FEM-DDC

8 channels for output of voltages and/or currents and 16 discrete input and output channels for digital control signals.

 

*)AVL F-FEM 19" are also available as snap-in units. With the F-FEM Snap-in product family the data acquisition is shifted to the pallet in a vibration and IP65-protected manner.

 

F-FEM Snap-in:

  • Flexible equipment due to clever slot system for data acquisition and pressure measurement units.
  • Sensor cabling and pressure hosing already implemented in the setup area.
  • Quick pallet replacement: connection via one multiple connector only.
  • Vibration and IP65 protection.

 

 

AVL F-FEM for DIN rail mounting 

F-FEM-DIO

16 discrete input and output channels for digital control signals.

F-FEM-CNT

4 + 2 counter channels for event counting, frequency or engine speed measurement.

F-FEM-DAC

4 channels for output of voltages and/or current signals as well as 2 channels for output of frequency, PWM or simulation of engine speed pick-up signals.

 


Benefits at a Glance

  • Reduction of measurement cycles leading to shorter tests; high reproducibility of measurement results
  • Measurements on batteries, e-motors and inverters with up to +/- 1,000V
  • No spare channels required: many different signal types are supported on one channel
  • Full synchronization of the measurement channels to each other and to the automation system with max. jitter < 0.1μs
  • Short parameterization times
  • Automatic calibration of measurement channels (option)
