Frequently Asked Questions

Q: What voltage range does the DC digital counter module support?

A: The module operates on a wide input voltage range of DC 4V to 25V, making it compatible with most common power supplies used in electronics and automation projects.

Q: Does the counter module retain its count after power is switched off?

A: Yes. This module features a built-in power-off memory function that saves the current count value even when power is disconnected. When power is restored, the counter resumes from where it left off.

Q: What type of trigger signal does this module accept?

A: The counter module uses low-level signal switching, meaning it triggers a count increment when it receives a low-level (logic LOW) input signal. This makes it compatible with many microcontrollers, PLCs, and digital logic circuits.

Q: What is the maximum count this module can display?

A: The 4-digit LED display supports counting from 0 up to 9999. Once the maximum count is reached, the counter resets back to 0 and continues counting.
