DC 5V 12V 24V Infinite Cycle Delay Timing Relay Timer Control ON-OFF Loop Switch Module Double Adjustable 0~120 Minutes

Special note: Trigger ons are not required, if you need to power up, start looping instead of preing the on. Then short the trigger line of the on. product descrtion: This module uses a single-ch microcomputer as the main control core with high time precision. The built-in watchdog circuit and dedicated reset ch 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 s. 2. In the delayed working proce, if it is triggered again, the delay will be interrupted immediately. Tyal application reference: 1. Time-limited working equment, for example, automatic power-off after 5 minutes of on triggering. 2. The hine 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 equment. Performance: Jumper OP1: 1 second to 100 seconds, adjustment accuracy 0.1 second Jumper OP2: 1 second to 15 minutes, accuracy 1 second Delay error of no more than 2% under various temperatures and humidity Features: 1. It adopts industrial grade single-ch microcomputer to control time with high precision and stable performance. 2. Two adjustable s 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 on. It is also poible 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. The time range is divided into 0-100 seconds, 0-15 minutes, 0-30 minutes, 0-60 minutes, 0-120 minutes, 0-24 hours and other specifications. 5. The voltage range is 5V 12V 24V three specifications. Basic working princle: Taking the factory standard setting as an example, the red LED will light when the power is turned on, and the relay is in the off state. When the trigger terminal is shorted, the green LED of the module lights up and immediately enters the working state. When it is triggered again in the working state, it will stop working. In the working state, the relay will pa T1 seconds, break T2 seconds, pa T1 seconds, break T2 seconds..... infinite loop. T1, T2 are the length of time the user adjusts through the adjustable .
