DC4-40V 0-9999 Electronic Digital Counter Module With Power Cut Memory Function

DC4-40V Digital Counter Module (0-9999) with Power Cut Memory is a robust and highly versatile electronic module designed for accurately counting pulses across a wide range of industrial and hobby applications. This device features a wide operating voltage range (DC 4-40V), ensuring compatibility with numerous power supplies and systems. Furthermore, its critical power-cut memory function guarantees the counter retains the last count value even after power loss, eliminating the need for manual resets or lost data. Consequently, this module delivers reliable, four-digit counting up to 9999, which engineers frequently integrate into production lines, monitoring equipment, and automated machinery where persistent data integrity is paramount.

Key Features:

• Power Cut Memory (Non-Volatile): The embedded memory chip automatically saves the current count value upon power failure and restores it upon power-up, ensuring data persistence.
• Wide Voltage Input: The module accepts a broad DC input voltage ranging from 4 V to 40 V, offering flexibility across various control system architectures.
• High Count Range: A bright, easy-to-read 4-digit LED display clearly presents the count from 0000 to 9999.
• Simple Push-Button Control: Dedicated on-board buttons allow users to easily reset the count to zero or pause/resume the counting function.
• Robust Design: Built with industrial-grade components, this counter delivers stable and reliable performance in demanding operating environments.

Dimensions:

• Module Length: ≈ 79 mm
• Module Width: ≈ 42 mm
• Module Height (Incl. display): ≈ 25 mm
• Mounting Holes: Four ≈ 3.0 mm diameter holes

Pinout and Wiring:

• VCC (+): Connect the positive side of the DC power supply (4 V to 40 V).
• GND (−): Connect the negative side of the DC power supply (Ground).
• Input (Pulse Signal): Connect this terminal to the pulse source (e.g., limit switch, Hall sensor, proximity sensor). A low-level pulse triggers the count.
• Wiring Note: Always use shielded wire for the pulse input line, especially over long distances, to minimize noise interference, which otherwise could cause spurious counts.
