What Is the DHC JDM15-4 Digital Display Counter?

The DHC JDM15-4 is a digital electronic counter with an LED or LCD display, powered by 100-240VAC wide-range input. It counts pulses from sensors, switches, or relay contacts and displays the accumulated count — a fundamental tool in production monitoring, batch control, and packaging line piece counting.

In short: A panel-mount DHC digital counter that tallies production units, rotations, or events from sensor input — 100-240V universal power, 4-digit display for manufacturing line counting applications.

Key Features

1. Wide-Range 100-240VAC Power

What it means: Accepts any mains voltage from 100V to 240V without transformer or voltage selection.
Why it matters: The same model works in factories across Japan (100V), North America (120V), Europe (230V), and China (220V).
Result: Standardized spare part across global manufacturing locations — no region-specific variants.

2. 4-Digit Digital Display

What it means: Shows count from 0000 to 9999 with clear LED or LCD readout.
Why it matters: Operators can read the count from across the production floor without approaching the panel.
Result: Quick visual confirmation of production progress at a glance.

3. Contact or Sensor Input

What it means: Counts from dry contact closures (relays, switches), NPN/PNP sensors, or encoder pulses.
Why it matters: Compatible with virtually any sensing method — limit switches, photoelectric sensors, proximity sensors, or rotary encoders.
Result: Flexible integration into existing production line sensor infrastructure.

Key Specifications

Typical Applications

• Assembly Line Piece Counting: Tallying completed units as they pass a photoelectric sensor at the end of a conveyor line.
• Coil Winding Turns Counting: Recording the number of wire turns in transformer and motor coil winding machines.
• Packaging Batch Control: Triggering a box change or label print after a preset number of items pass the counting station.
• Press Stroke Counting: Monitoring tooling life by counting press strokes for preventive die maintenance scheduling.

Frequently Asked Questions

"Can this counter count at high speed?"

Digital counters of this type typically handle input frequencies up to 30-1000 counts per second depending on the model configuration. Check the maximum counting speed (Hz) specification for your specific JDM15-4 variant. For high-speed encoder counting above 1kHz, a dedicated high-speed counter module may be required.

"Does this model have a preset or batch function?"

Verify from the product label whether this JDM15-4 variant includes preset/batch functionality. Some models in the series have a relay output that activates when the count reaches a preset value, making them suitable for batch cut-off control. Base models may be count-and-display only without output relay.

"How is the counter reset?"

Reset is typically via a front-panel button, a remote contact closure on the reset terminal, or both. For automated reset in continuous cycling applications, wire a reset pulse from a PLC output or a timer contact to the reset input terminal. Consult the DHC wiring diagram for terminal identification.
