Features: High precision timer relay module with stable and reliable performance. Supports reverse input protection and equipped with a trigger button switch. Power on and press the trigger switch to turn on the load; the load turns off automatically after the delay time. Adjustable delay time from 1 to 10 seconds using a potentiometer. For longer delay, replace with a larger capacitor or potentiometer. Suitable for use in timer-based equipment, robotics, intelligent product development, automation systems, PLC development, smart home security alarm delays, and electronic projects.
