6.17.1 PCD3.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 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 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, max. 10% ripple
Circuit type:
Electrically coupled, not short circuit protected,
positive switching
Voltage drop: typically 2 V at 500 mA
Output delay: < 10 µs, (longer for inductive load because of
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: -25…+85°C
Noise immunity: EC mark according to EN 50 081-1 and EN 50 082-2
Programming: Based on Saia PCD
®
user program and pre-programmed
function blocks (FB). There are other FBs for use in the RIO
head station.
