1x Counter 24 V, 500 kHz, 32 Bit

Counters are used to detect pulses that are faster than a controller’s cycles, i.e., signals that the controller will be unable to detect properly and that therefore need to be pre-processed.

  • 32-bit counter
  • Up to 500 KHz (4-fold evaluation)
  • Accommodates 24 V incremental encoders and proximity sensors
  • Filters: 10 kHz | 50 kHz | 100 kHz | 500 kHz
  • All inputs can be inverted
  • Limits for counter and measured readings
  • Hysteresis for input
  • Pulse duration for output
  • Refresh rate / averaging time for measuring mode
  • 8 bytes of input data (count and status)
  • 8 bytes of output data (preset count and commands)

Counters are used to detect pulses that are faster than a controller’s cycles, i.e., signals that the controller will be unable to detect properly and that therefore need to be pre-processed. 

The counter module detects the edges of 24 V signals as pulses. The impulses can be counted or converted into a frequency, rotational speed, or period. The counter module features an additional 24 V input and a 24 V output for a direct response to start pulses and to quick system state changes.
