NE555 Delay Timer Switch 12V Relay Module (0-10 seconds)

The NE555 Delay Timer Switch 12V Relay Module is a single-channel SPDT relay board built around the NE555 timer IC — one of the most reliable and widely used timer circuits in electronics — that triggers a relay contact after an adjustable delay between 0 and 10 seconds, set by turning the onboard potentiometer. This relay module runs on 5V DC, making it directly powerable from an Arduino’s 5V output pin or any standard USB power source without needing a separate higher-voltage supply, which is a practical convenience over relay timer modules that require 6V or higher input.

The ne555 timer module uses a low-level trigger — meaning the timing cycle starts when the trigger pin is pulled below 1V, such as by connecting it to Arduino digital LOW output or a button connected to GND — which is the opposite of high-level triggered relay modules and suits circuits where the natural idle state of the trigger line is high. The ne555 time delay switch’s defined 0-10 second adjustment range gives a clear and predictable window for setting the delay, unlike modules where the potentiometer range is unspecified.

The delay timer relay switch’s onboard power LED and relay status LED show at a glance whether the module is powered and whether the relay contact is currently open or closed. This ne555 delay timer module is ideal for Arduino timed delay switching and standalone NE555 timer relay project builds. Available from StemVolt, offering quality electronics parts at competitive prices.
