PCD2.H100, counting module up to 20 kHz
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
