Frequently Asked Questions

Q: What is the default delay time range for the NE555 timer switch module?

A: The default adjustable delay time range is 0 to 10 seconds, set via the onboard potentiometer. You can extend this range by replacing the onboard capacitor with a higher-value one to achieve longer delay intervals.

Q: What voltage and load can this NE555 delay relay module handle?

A: The module operates on DC 12V input (with an optional 5V version available). Its output relay can switch AC loads up to 250V / 10A and DC loads up to 30V / 10A, with a maximum load capacity of 2200W.

Q: Can I use this delay timer module in automotive applications?

A: Yes. The module is well-suited for vehicle electronics, where a timed delay at startup helps protect components and devices from inrush current surges when power is first applied.
