Description:

ASK-2D Compact Electronic Counter – Preset Counting with Multiplier Selection for Industrial Automation

The ASK-2D is a compact, panel‑mount electronic counter engineered for precise counting and control in industrial automation, production monitoring, and process control applications. Featuring a universal AC/DC power supply (DC12‑48V and AC12‑380V 50Hz), flexible input options (contact or photoelectric sensor), and a robust 3A output contact, this counter offers exceptional versatility in a space‑saving 50×62 mm panel cutout. With an adjustable counting range of 1‑999 and a three‑position multiplier (×1, ×10, ×100) selectable via DIP switches, the ASK‑2D can handle everything from piece counting on packaging lines to batch control in mixing processes. Its low power consumption, high counting speed (30 counts/second), and long mechanical life make it an ideal choice for control panels, OEM equipment, and field upgrades worldwide.

Universal Power Supply for Global Installation

The ASK‑2D operates on an exceptionally wide voltage range: DC12V‑48V and AC12V‑380V (50Hz). This universal compatibility allows the counter to be used in virtually any control system – from low‑voltage DC logic circuits (e.g., PLC outputs, battery‑backed systems, sensors) to standard AC mains up to 380V, covering industrial power systems across the globe. This eliminates the need for multiple counter models for different voltages, simplifying inventory and reducing costs. The low power consumption ensures minimal heat generation inside enclosures, making it suitable for densely populated panels.

Compact Panel‑Mount Design

Designed for front‑panel installation, the ASK‑2D requires a 50×62 mm mounting hole – a compact footprint that allows high‑density placement on control cabinets, machine consoles, or portable test boxes. Weighing ≈150g, it is lightweight yet sturdy. The front panel features a clear LED display, preset adjustment dials, and DIP switches for multiplier selection. The intuitive layout enables quick, tool‑free setting of the count value and multiplier, reducing setup errors and training time.

Flexible Input and Preset Counting with Multiplier Selection

The ASK‑2D accepts input signals from contact closures (push‑buttons, limit switches, relays) or photoelectric sensors (PNP/NPN), making it compatible with a wide variety of industrial sensors and manual triggers. The counting method is accumulation (up‑counting), where each input pulse increments the displayed value.

Key counting features include:

· Counting Range: 1 to 999 (preset value adjustable via front‑panel thumbwheel switches).
· Multiplier Selection: Three DIP‑switch‑selectable multipliers – ×1 (counts 1‑999), ×10 (counts 10‑9990), and ×100 (counts 100‑99900). This allows the counter to handle both small‑batch and high‑volume applications without changing the hardware.
· Counting Speed: Up to 30 counts per second – fast enough for most production line counting tasks (e.g., conveyor belt piece counting, packaging line product counting).

When the accumulated count reaches the preset value, the counter activates its output relay, which can be used to stop a conveyor, sound an alarm, or initiate another control action. The counter can then be manually reset or automatically reset depending on the configuration.

Robust Output Contact for Direct Load Control

Equipped with a control output rated at 3A at 220V AC or 28V DC, the ASK‑2D can directly switch a variety of loads, including contactor coils, solenoid valves, small motors, indicator lamps, buzzers, and pilot lights. The output contact is designed for long‑term reliability, with a mechanical life of 10⁷ operations and an electrical life of 10³ operations at rated load. This makes it suitable for high‑cycle applications such as batch counting, automated filling, and conveyor control.

High Noise Immunity and Reliable Input Detection

The ASK‑2D is designed with industrial environments in mind. Its input circuit includes filtering to reject contact bounce and electrical noise, ensuring reliable counting even with mechanical switches or in electrically noisy environments. The input accepts both NPN and PNP type sensors (via appropriate wiring), providing flexibility for integration with existing sensor types. The counting speed of 30 counts/second ensures that fast‑moving products on a conveyor line are accurately counted.

Durable Construction for Long Service Life

The ASK‑2D is built to operate reliably under typical industrial conditions:

· Operating temperature: -10°C to +50°C – suitable for unheated workshops, outdoor enclosures, and climate‑controlled rooms.
· Humidity: 35% to 85% (non‑condensing) – performs well in most environments without risk of moisture damage.

The counter's robust construction, high insulation resistance, and durable contacts ensure stable operation and long life even in moderately demanding settings.

Typical Applications

The versatility of the ASK‑2D makes it ideal for countless counting and batching applications:

· Packaging Lines: Counting products (bottles, boxes, bags) as they pass on a conveyor, with preset batch control to stop the conveyor when a target count is reached.
· Parts Counting: Counting small components (screws, bearings, electronic parts) for kitting or packaging.
· Length Measurement: Using a rotary encoder or proximity sensor to count revolutions and convert to length (with appropriate multiplier).
· Batching & Dosing: Controlling the number of items or cycles in mixing, filling, or dispensing processes.
· Production Monitoring: Tracking production output per shift or per batch for efficiency analysis.
· Machine Cycle Counting: Counting the number of operations performed by a machine for maintenance scheduling.
· Conveyor Control: Counting items to trigger diverters, pushers, or stackers.

Easy Installation and Operation

Mounting the ASK‑2D is straightforward: cut a 50×62 mm rectangular hole in the panel, insert the counter, and secure it with the included brackets. Connect the power supply (DC12‑48V or AC12‑380V) and the input signal (contact or photoelectric sensor) to the appropriate terminals. Set the desired count value using the thumbwheel switches and select the multiplier via the DIP switches. No complex programming or external tools are needed. The clear display and logical layout minimize wiring errors and reduce installation time.

Conclusion

The ASK‑2D Compact Electronic Counter combines a space‑saving panel‑mount design, universal AC/DC power supply (12‑380V AC / 12‑48V DC), flexible input options, and a robust 3A output with an adjustable counting range of 1‑999 and three multiplier selections (×1, ×10, ×100). Its high counting speed, durable construction, and long mechanical life ensure reliable operation in demanding industrial environments. Whether you need to count products on a fast‑moving conveyor or batch‑control a filling machine, the ASK‑2D delivers consistent, repeatable performance. For engineers, panel builders, and maintenance professionals seeking an affordable, versatile, and durable counting solution, the ASK‑2D is the perfect choice. Install it once and enjoy years of dependable service.
