DNx-CT-602, DNA-CT-602, DNR-CT-602, DNF-CT-602

The DNx-CT-602 board is a differential counter/timer interface that provides four independent 32-bit channels, each one having overvoltage protection and optoisolation. They can act as an event counter, perform width/ period measurements and run in quadrature-encoder mode where the user sets the direction of the counting. For output modes, the layer offers 1-shot and Universal PWM operation. It also provides edge detection on the ClockIn and Gate pins. The DNx-CT-602 is software compatible with the DNx-CT-601 except for additional commands, which configure and control the Trigger output pins.

The DNx-CT-602 provides the following 8 counting modes which will accommodate most data acquisition and data logging requirements:

  • Timer
  • PWM generator
  • Continuously updated PWM generator (buffered)
  • Bin counter (number of pulses in specified time interval)
  • Pulse width
  • Pulse period (232 periods max)
  • Quadrature encoder
  • Timebase operation



  • PowerDNA
  • UEIModbus
