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.
