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