This 12V Time Delay Relay-On offers precise control over when a circuit activates, making it ideal for automotive applications that require a delayed power-on function. Designed in a standard 5-pin automotive relay style without a mounting tab, this SPDT relay features an adjustable delay timer from 1 second to 1 minute, set via an internal potentiometer.
The relay activates only after a delay period begins once voltage is removed from the coil. A momentary or low-voltage trigger (as low as 1V) can initiate the timer, and once triggered, the relay latches based on the preset delay. Removing the +12V input resets the timer, offering flexible control for custom circuits, power management, or timing logic.
Built-in protections like a diode prevent timer feedback, and a green LED indicator shows relay status. With a 20A/30A contact rating, this relay is both powerful and precise, supporting normally open and normally closed configurations.
