High Speed Modules


  • 32-bit counter
  • 8 up-counter/frequency channels
  • 1 ~ 32767 us digital filter
  • Falling/Rising/Both edge trigger
  • RoHS compliance
  • 3000 VDC isolation from output to backplane
  • 3000 VDC isolation from output to frame ground
  • Redundancy
  • No error counting when redundant switching


The F-8084 is a 32-bit high speed up-counter/frequency module. It can count up to 500 KHz input signal, and accuracy of the frequency mode is +/-0.4% FSR. The F-8084 features many diagnostic like some failures of communication, EEPROM, WDT, decoder, etc. When the modules are in the redundant mode and a failure occurs the slave module will take over as soon as possible. Moreover, the redundant switching is not only fast but also reliable for data exchanging. Thus, users can easily to use F-8084 to count.
