6.15.1 PCD2.H100,countingmoduleupto20kHz,1channel
Application
Simple counting module, comprising two inputs "A" and "B" plus one direct control
outputmarked“CCO”;allowscountingofthenumberofrevolutionsorthecalculation
ofdistances(pulses)andthemeasurementbycountingofpulseswithinalogical
ANDgate(secondinput)
Typical areas of application:
● Countingrevolutionsordistances(impulses)
● Presetting a count value and switching off output CCO when Counter = 0
● Measurement by counting: measuring signals counted only when particular
conditions are met, e.g. photoelectric barrier covered
● Counting with recognition of count direction for incremental shaft encoders
providing simple motion control
Technical data

Counting range: 0 … 65,535(16bit)(canbeextendedwithCPUcounters)
Counting frequency: max.20kHz(atpulse/pauseratio50%)
Data protection: All data in this module are volatile
(non-volatilePCDregistersareavailable).
Digital inputs
“IN-A”and“IN-B”signalvoltages: Nominal voltage: 24 VDC
“low"range:  -30 … +5 V
“high"range:  +15 … 30 V for source operation
Input current: typically 7.5 mA
Inputler: 25 kHz
Process output
Counter controlled output CCO: counteroutput(switcheswhencountis0or65,535)
Current range: 5 … 500mA (max.currentleakage1mA)
  (min.loadresistance48Ωin  
  voltagerange5..24V).

Circuit type: Electrically coupled, not short circuit protected,
positive switching
Voltage drop: typically 2V at 500 mA
Output delay: <10µs, (longerforinductiveloadduetoprotec-
tivediode).
