        More Information

        Overview Manuals Counting Modes Signal Quality Immediate Output Commissioning

        Features:

        • Counts pulse or quadrature inputs at rates up to 50 kHz independently of PLC scan.
        • Preset and ring modes support position, rate, and bounded-count applications.
        • A local open-collector output can react to preset conditions without CPU latency.
        The module consumes input and output reference space for commands, counts, and status, but the physical pulse processing occurs locally. This separation prevents fast edges from being missed by the normal scan.

        DIP settings select how the two inputs are interpreted. Direction errors can result from swapped quadrature phases or an up/down configuration that does not match the sensor.

        The immediate output is a low-power open-collector point, not an unrestricted actuator source. Confirm polarity, external supply, and load current before using it to trigger equipment.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Choosing how pulse inputs are interpreted

        • Quadrature: A and B phase establish movement and direction.
        • Up/down: Separate inputs increment and decrement the accumulator.
        • Preset mode: A defined count can trigger local action.
        • Ring mode: The accumulator operates within configured rollover boundaries.

        Conditions for reliable high-speed counting

        • Voltage class: Match the input to the sensor electrical level.
        • Pulse rate: Keep frequency and pulse width within the supported limits.
        • Shielding: Route and terminate the counter cable to reduce noise.
        • Phase order: Preserve quadrature conductor identity during replacement.

        Using the local preset reaction safely

        • Open collector: The module switches a compatible external DC load.
        • Current limit: Do not exceed the point rating.
        • Polarity: Wire the external source and load for the intended logic.
        • Interposing device: Use a relay or driver when the field load is too large.

        Proving the counter against machine motion

        • Zero reference: Establish a known physical starting position.
        • Direction test: Move slowly in both directions and compare counts.
        • Scale check: Verify pulses per unit across a measured distance.
        • Preset test: Confirm output action at a safe operating speed.
        Description
        The General Electric IC655APU510 is a Series Five High-Speed Counter Module that handles position, rate, speed, flow, and event counting outside the normal PLC scan. Dedicated counting hardware accumulates pulse edges while the controller exchanges status and commands through the assigned references.

        Two inputs on IC655APU510 can work as quadrature A/B signals or as separate up and down channels. Sensor voltage class, source or sink arrangement, phase relationship, and pulse quality must suit the selected mode, since wiring reversal or noise can look like an accumulator error.

        Preset and ring modes give IC655APU510 different ways to bound the count. Its open-collector output can react locally when a preset condition is reached instead of waiting for a CPU scan, providing a predictable hardware response for the connected load.

        Input rates up to 50 kHz make signal integrity part of the functional setup for IC655APU510. Direction, counts per machine unit, rollover behavior, shield routing, and the output load should all be proved during commissioning before the counter is allowed to control automatic motion or flow.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why does IC655APU510 count in the wrong direction?
        During a controlled IC655APU510 test, check quadrature A/B phase order or the selected up/down mode, then verify sensor polarity and wiring before changing scale or accumulator logic.
        What causes extra IC655APU510 counts when machinery is stopped?
        When reviewing IC655APU510 compatibility, inspect shield termination, input reference, cable routing, loose connections, and sensor bounce; high-speed inputs can register electrical noise that ordinary PLC points ignore.
        Why can IC655APU510 miss pulses at high machine speed?
        At the IC655APU510 output stage, confirm pulse width and frequency stay within the module limits, measure signal amplitude at the module, and check whether the sensor and cabling preserve clean edges.
        Can the immediate IC655APU510 output drive a large solenoid directly?
        Across the IC655APU510 installation, only loads within the open-collector voltage and current rating are suitable; otherwise use a compatible interposing device and appropriate suppression.
        What should be tested before changing IC655APU510 ring mode?
        When isolating an IC655APU510 fault, record the current preset, rollover limits, count direction, output action, and machine zero so the new behavior cannot create an unexpected cycle.
        With IC655APU510, how should counts be converted into engineering units?
        During an IC655APU510 wiring check, establish pulses per revolution or unit of travel from the sensor, verify direction and gearing, then scale the module value in the PLC without hiding missing or extra counts.
        What should be preserved during IC655APU510 replacement?
        At the IC655APU510 interface, record DIP positions, reference allocation, presets, mode, output wiring, sensor voltage class, and the counts-per-unit value used by the application.
