REVO Micro Data Acquisition Unit (μDAU)

The REVO Micro Data Acquisition Unit (μDAU) series is a miniature hermetically sealed acquisition unit, useful for installation in harsh and remote locations to both simplify wiring harness design and improve signal fidelity by measuring input signals close to the source. Captive fasteners are included to minimize risks of FOD. 

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 physical hardware in different applications.

Primary output capability is through a high speed ARINC-429 bus.

Total input capability is determined by exact signal selection and pin availability, e.g.

  • Differential (input): 11 channels
  • Single Ended (input): 22 channels
  • Output transcievers:2 channels
  • Auxiliary Outputs: 1 protected 28VDC

Input signal types include:

  • Analog DC (0-5V, +/-5V, +/-10V, +/-20V) 
  • Thermocouple (Configurable type) 
  • Analog AC (Single phase, Resolver, Synchro) 
  • Frequency 
  • Digital Data Buses (ARINC-429, RS-422, RS-232)

Primary output capability is through a high speed ARINC-429 bus.
