DH48J-H YANGPU Digital Preset LED Electronic Counter (AC220V)

The YANGPU DH48J-H is an industrial-grade, high-precision digital electronic preset counter designed by Yangpu Electric Factory for automated production lines, packaging machinery, textiles, and stamping operations. This device serves as an intelligent batch-counting relay that tallies incoming electrical pulse signals or mechanical contact closures and triggers an internal output relay once a user-defined preset target is reached.

As shown in image_3547a0.jpg, the front interface features a crisp, bright 4-digit red LED digital display paired with a durable mechanical thumbwheel potentiometer array underneath. The thumbwheel keys allow machine operators to easily dial in a precise target count value from 1 to 9999. Running on a standard industrial AC 220V power supply, the counter features a built-in front panel manual reset button ("R") for instant cycle clearing, alongside back-end options for automatic or remote circuit-based resetting. Its standard square face factor is optimized for clean flush panel-mounting or standard 8-pin base socket installations.
