DSP  AD5430-13(PWM I/O board)

Features

This is an interface board for multiple channel PWM input/output, for the AD5430 series bus specification. The PWM feature of the AD5430-
06 (Auto I/O) is an optional upgrade.

  • Multiple channel capability: PWM_IN 14ch, PWM_OUT 14ch , 5 channels AC input with electromagnetic pick up capability.
  • All channels: 0.1 Hz to 20 kHz, 0.1%
  • 20 kHz maximum model cycle for the AD5435 model; otherwise dependent to on the model scale.
