5.16.1 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o󰀨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
Number of systems: 1
Counting range: 0 … 65,535 (16 bit, can be ext. with CPU counters)
Counting frequency: max. 20 kHz (at pulse/pause ratio 50 %)
Data protection: All data in this module are volatile
(non-volatile Saia 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).
Voltage range: 5 … 32Vsmoothed,residual ripple max. 10 %
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
protective diode).
Power supply
External supply 5 … 32VDC (for supply of CCO output only)
Internal current consumption:
(from +5 V bus)
max. 90 mA
Internal current consumption:
(from V+ bus)
0 mA
External current consumption: CCO output load current
Operational conditions
Ambient temperature operation: 0 … +55°Cwithoutforcedventilation,
storage: -20 … +85°C
Noise immunity: EC mark according to EN 61 000-6-3 / EN 61 000-6-2
Programming: Based on Saia PCD
®
user program and pre-pro-
grammed function blocks (FB).
Count modes: Selectable with jumper
Terminals: Pluggable 10-pole screw terminal block
(4 405 4847 0), for wires up to 1.5 mm²
