DC 5V 12V 24V Adjustable Cycle 120min Timer Delay On/Off Switch Relay Module 0~120 Minutes 1 Channel Timer Control Switch Relays (Size : 12V)

RelaysProduct Description:This module uses a single-chip microcomputer as the main control core with high time precision. The built-in watchdog circuit and dedicated reset chip of the MCU work stably and reliably.Single 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 powered off for 1 minute.3. The aquarium water pump intermittently pumps water to pump oxygen.4. Other time control equipment.Performance:Jumper OP1: 1 second to 100 seconds, adjustment accuracy 0.1 secondJumper OP2: 1 second to 15 minutes, accuracy 1 secondDelay error of no more than 2% under various temperatures and humidityFeatures: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 disconnecte
