REVO Data Acquisition Unit (DAU)
The REVO Data Acquisition Unit (DAU) series features an internal back plane with up to eight interchangeable cards to support rapid customisation and configuration for various applications.
The unit supports a dual channel configuration with redundant acquisition cards and redundant processing used to support higher integrity applications.
FPGA based processing coupled with high speed analog front ends allows both digital (e.g. ARINC-429) and analog (e.g. Synchro) signals to be measured with the same pins in different applications.
Total I/O capability is determined by exact card configurations and pin availability, e.g.
Expansion capabilities via internal daughter cards include:
- Differential (input): 48 channels
- Single Ended (input): 96 channels
- Transcievers: 6 channels
- Discrete Outputs: 2 channels
- Auxiliary Outputs: 4 protected 28VDC
