Электрическое ядро & Механические параметры

Типичные сценарии применения

Equipment operation cycle counting, production line workpiece counting, total output statistics for stamping/packaging/textile machinery. Suitable for low-speed contact pulse signals (бесконтактные переключатели, концевые выключатели, контакты реле). Not applicable for high-frequency pulses.

Руководство по устранению неполадок

1. No counting: Check 24V power supply; verify reliable ON/OFF of input contacts. Contact bounce may cause missing counts; confirm pulse frequency ≤25 Hz.
2. Не удалось выполнить сброс: Jammed manual reset mechanism or worn internal gears (common ageing fault for electromechanical counters).
3. Erratic counting / extra counts: Contact bounce; add RC debounce circuit; pulse frequency exceeds 25 Гц.
4. Stuck digits: Worn internal gears, irreversible mechanical damage; требуется замена.

Альтернативный выбор (Replacement for Discontinued Unit)

1. Equivalent mechanical counters: Compare panel cutout dimensions. Select alternative 6-digit electromechanical totalising counters, verify reset function and 25 Hz limit.
2. Electronic pulse counters: Шнайдер XBT series or domestic electronic counters, support higher frequency, external power supply required, some models offer power-fail data retention.

Примечание: Mechanical models limited to 25 Hz max. Electronic counters must be selected if field pulse >25 Гц.

Установка & Аксессуары

Panel cutout size 20×30 mm, front panel snap-in mounting; AMP lug wiring, incompatible with standard screw terminals.

Typical Application Cases of Schneider XBKT60000U10M Electromechanical Totalising Counter

Core characteristics preamble: 6-digit mechanical accumulation, Питание 24 В постоянного тока, dry contact input, Макс 25 Гц, front panel manual reset, permanent value retention after power loss. Optimized for low-speed contact pulse scenarios; unsuitable for high-frequency pulses.

Случай 1: Stamping Machine – Cumulative Mold Stroke Counting

Сценарий

Маленький & medium mechanical stamping press, total stroke counting for mold life management. Schedule maintenance/mold repair once target stroke count is reached.

Решение

1. Signal Acquisition: Limit switch actuated when slide reaches bottom dead centre, dry contact signal wired to XBKT counter input; DC24V sourced from machine control circuit.
2. Монтаж: Embedded into machine operation panel, 20×30 mm cutout.
3. Логика: +1 count for every completed stamping cycle upon contact closure; count value preserved after power cut. Rotate front reset knob to zero when mold is replaced.

Преимущества

Direct-read mechanical rollers, readable under strong light and dusty workshop environments; no battery required to retain cumulative data.

Ограничения

Stamping cycle frequency cannot exceed 25 counts/second. RC debounce is required to avoid miscounting caused by contact bounce.

Случай 2: Packaging Line – Total Finished Carton Output Counting

Сценарий

Low-speed carton packaging line (цикл >0.04 с). Count total cartons off the line for shift/monthly production logging, acting as independent hardware backup counter separate from PLC.

Решение

Photoelectric proximity sensor detects carton presence and outputs dry contact pulse to XBKT; PLC performs real-time monitoring, while XBKT serves as independent hardware totaliser.

Ценить

Cumulative production data remains intact even if PLC stops or power fails, preventing data loss. Operators read values directly without PC access. Manual reset for new production shifts.

Случай 3: Injection Molding Machine – Mold Open/Close Cycle Counting

Сценарий

Horizontal injection molding machine. Count total mold open-close cycles to predict wear on mold, guide pins and ejector pins for predictive maintenance planning.

Решение

Use limit switch signal triggered when mold is fully closed to drive counter; DC24V from injection machine control power supply.

Ключевые моменты

Capture stable mold fully closed signal only. Avoid solenoid valve signals (prone to bounce and false counts).

Count value retained during power-off maintenance; manual reset upon mold replacement.

Случай 4: Conveyor Sorting Equipment – Cumulative Material Count

Сценарий

Low-speed belt sorting line (material interval >40 РС). Count total workpieces passing through sorting station.

Решение

Diffuse photoelectric sensor detects incoming material and sends dry contact pulse; XBKT performs total accumulation.

Suitable for cartons and large workpieces. Not recommended for high-speed small-item sorting (frequency exceeding 25 Гц), electronic counters required instead.

Случай 5: Hydraulic Equipment – Cylinder Actuation Cycle Count

Сценарий

Hydraulic workholding fixtures and hydraulic bending machines. Count reciprocating cylinder cycles to evaluate service life of seals and cylinder assembly.

Решение

Magnetic proximity switch triggered when cylinder fully extends, dry contact pulse for counting; unit installed inside control cabinet panel.

Функции

Robust mechanical gear design suitable for high vibration industrial environments; immune to EMI interference from variable frequency drives and will not lose counts.

Случай 6: Valve Test Bench – Valve Opening/Closing Durability Cycle Test

Сценарий

Fatigue life test bench for gate valves and butterfly valves. Count total valve open-close cycles.

Решение

Limit switch at fully open valve position provides counting pulse; 24 В постоянного тока. Manual reset when test batch changes.

Matches XBKT’s strength for low-speed dry-contact counting and power-fail retention, acts as hardware checksum against upper computer logged data.

General Notes for Selection & Операция (Применимо ко всем случаям)

1. 25 Hz pulse limit: Event interval ≥40 ms. Electronic counters must be used for faster cycles.
2. Dry contact input only: Accept relays, limit switches and proximity switch passive contacts; cannot connect voltage pulses directly.
3. Environmental tolerance: -40~+85°C operating range, suitable for dusty workshops; avoid heavy oil immersion on digit window.
4. Статус продукта: Данная модель снята с производства. Not recommended for new projects. Spare part replacement for existing machines can use alternative domestic 6-digit electromechanical counters or Schneider electronic counters.

Counting Accuracy of Schneider XBKT60000U10M

This is an electromechanical totalising counter. Unlike measuring instruments with percentage accuracy, official datasheets do not specify ±xx% error. Core definition: Under rated operating conditions, 1 pulse = 1 count with zero pulse error.

1. Counting Resolution

1 count (1 цифра). 6-digit mechanical roller, display range: 000000 ~ 999999, minimum counting unit = 1 event.

2. Nominal Counting Accuracy (Ideal Operating Condition)

All conditions met: 1 valid input pulse = accurate +1 increment, no inherent counting error

Dry contact input pulse ≤25 Hz

Good contact debounce with no bounce or duplicate pulses

DC24V supply within 19.2~26.4 V

Рабочая температура -40 ~ +85°C, no continuous heavy shock/vibration

Intact mechanical gears without jamming or wear

Nature: It is an event counter, not a metering instrument. New unit under rated conditions will not lose or add spurious counts, no percentage error defined in factory documentation.

3. Sources of Field Count Error (Not inherent counter inaccuracy)
4. Contact bounce (most frequent cause): Mechanical bounce of limit/relay contacts generates multiple pulses from one single action → extra counts.
5. Pulse frequency over 25 Гц: Signals arrive faster than internal electromagnetic mechanism can respond → lost counts.
6. Ageing and mechanical wear: Long-term operation causes gear wear and jamming → missed counts or stuck digits (ageing failure, requires replacement).
7. Supply voltage drop: Insufficient voltage fails to pull in electromagnetic actuator → no counting action.
8. Критическое различие

✅ New unit with compliant pulses: Counting Accuracy = ±0 counts

❌ Percentage error metrics like ±0.1%, ±1% do NOT apply; no such parameter in official documentation.

Visual reading error for mechanical rollers: Max ±0.5 digit, occurs when roller sits between two numerals (human reading deviation).

5. Совет по выбору

For metering-grade precision (percentage error requirement), electromechanical counters such as XBKT are unsuitable. Electronic pulse counters are recommended.
