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

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: 12V

Dimension: 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 interrupt
