The 6–30V Single Channel Power Relay Module with Adjustable Timer is a complete relay switching board that combines a power relay with an onboard timing circuit controlled by a potentiometer — so after receiving a 5V trigger signal, the module waits for the time delay set on the potentiometer and then switches the relay contact, which can control loads up to 10A on either AC mains up to 250V or DC circuits up to 30V. This power relay module can operate completely standalone without an Arduino or microcontroller — the timing is handled entirely by the onboard circuit, making it suitable for simple timed switching tasks where no programmable controller is available or needed.
The 6-30v relay module switch trigger’s 5V trigger input is directly compatible with Arduino and other 5V microcontroller GPIO pins, so when used with a microcontroller it can also act as a software-controlled relay that switches high-voltage or high-current loads safely from a low-voltage signal. The relay module with adjustable timing’s 6V to 30V supply range means it can be powered from a variety of sources in a project — a 12V DC adapter, a 9V battery, a 24V industrial supply, or any source within the range.
The adjustable timer relay module’s combined timer and relay on one board reduces the component count and wiring complexity compared to building the same function with a separate relay cube and timer circuit. Available from StemVolt, offering quality electronics modules.
