AOQDQDQD HCW-03 12V Relay Module with Infinite Cycle/Single Time/Delay Dual Adjustable/Multifunctional Relay Module/Dela

Features 1 It adopts industrial grade single chip microcomputer to control time with high precision and stable performance 2 Two adjustable resistors are used to adjust the time and the on time and off time can be independently adjusted 3 The external contact is activated and the timing is started by short circuiting with the self reset button It is also possible to short the triggers together and start counting down when power is turned on If it is triggered again during operation it will be disconnected immediately 4 Suitable for fish tank pump intermittent pumping oxygen other time control equipment Specifications Voltage 12VDimension 61 5 23 2mmSingle mode 1 Does not operate after power on the relay is turned on after the trigger and disconnected after the arrival time 2 During the delay after the relay is turned on trigger again and the delay will be interrupted immediately Loop mode 1 After the power is turned on it will not operate After the trigger the relay will be turned on and will be disconnected after reaching the T1 time Turns on after reaching T2 time In this cycle T1 and T2 are set by two adjustable resistors 2 In the delayed working process if it is triggered again the delay will be interrupted immediately Typical application reference 1 Time limited working equipment for example automatic power off after 5 minutes of button triggering 2 The machine repeats the test circuit for example a test that is energized for 1 minute and then po
