The BBG-520 is a full-size ISAbus card which accommodates up to six channels of Synchro/Resolver output using industry standard components. Outputs are programmable Synchro or Resolver and can be combined with external transformers and amplifiers to supply any desired amplitude and frequency.

The BBG-520 provides a status register and 12 bits of external I/O. Software drivers allow easy integration into a PC compatible computer.

  •   ISAbus Compatible
  •   1 TO 6 Synchro/Resolver Output
  •   Jumper Configurable for Synchro or Resolver Output
  •   Compatible with SBA Series for High Power Output
  •   Up to 2VA Output Without Using SBA
