Description:When powered on, the module starts a timer immediately (adjustable time range). The relay activates, connecting the relay's common terminal and the normally open termin al. After the time delay ends, the relay deactivates, connecting the common and normally closed terminal.Features:- Utilizes an imported high-quality delay chip for superior performance compared to the 555 chip.- Adjustable delay time ranging from 0.1 seconds to one hour, suitable for various needs.- Integrated power reversal protection diode ensures effective product protection.- Supports high current loads: AC 250V / 10A, DC 30V / 10A.- Time delay can be extended by adjusting the potentiometer clockwise.How it Works:- When the trigger terminal detects a momentary switch close, the timer function begins, closing the relay. Once the delay is complete, the relay reconnects to the normally closed terminal.- If another trigger signal is received during the delay, the module restarts the timing, continuing until the delay ends.- Delay time can be adjusted using switches S1, S2, S4, and the potentiometer to fine-tune the time range.Applications:- Suitable for dashcam GPS start protection, household appliances, electronic equipment protection, audio protection, industrial control, PLC control, electronic experiments, and robotics, among others.Note:- No instructions are provided, so please consider this before placing an order.Package Includes:- 1 x 12V Power-On Delay Relay Module Show more
