Description
Special note: Triggering the button is not necessary, if you need to power up it starts the cycle instead of going to a button press. Then please directly short the trigger line connected to the button.
This module uses a single-chip microcomputer as the main control core, with high time precision. The single-chip microcomputer has a built-in watchdog circuit and a dedicated reset chip, and the work is stable and reliable.
[Single mode]
1. No action after power-on, the relay is connected after triggering, and disconnected when the time is reached.
2. During the delay process after the relay is turned on, if it is triggered again, the delay will be interrupted immediately.
[loop mode]
1. No action after power-on, the relay is connected after triggering, and disconnected after reaching T1 time. Arrive at T2
connected after time. so cycle. T1 and T2 are separately set by two adjustable resistors.
2. During the delay working process, if it is triggered again, the delay will be interrupted immediately.
[Typical application reference]
1. Time-limited 1 working equipment, such as automatic power off after 5 minutes after each key is triggered.
2. The machine repeats the test circuit, such as 1 minute of power on and 1 minute of power off.
3. The fish tank pump pumps water and oxygen intermittently.
4. Other time control equipment.
[Performance]
When jumper OP1: 1 second to 100 seconds, the adjustment accuracy is 0.1 second
When jumper OP2: 1 second to 15 minutes, the accuracy is 1 second
The delay error does not exceed 2% under various temperature and humidity
Specification:
Maximum load capacity: 10A 250VAC, 10A 30VDC
Size: 70*20mm / 2.75*0.78"
Time error: <2%
T1 (relay off delay time), T2 (relay off delay time)
Primary Mode (Jumper OP3):
1. When the module is turned on, the relay will act when it is triggered, and after a delay of T1, the relay will be disconnected.
2. After the delay process is triggered, trigger it again to interrupt the delay immediately.
Loop Mode (Jumper OP4):
1. The module is turned on, the relay is turned on when it is triggered, the relay is turned off after a delay of T1, and the relay is turned on again after a delay of T2. this cycle. T1 and T2 are adjusted by two adjustable resistors respectively.
2. After the delay process is triggered, trigger it again to interrupt the delay immediately.
How to quickly set the time:
The time can be quickly set by measuring the voltage (Uc) of the resistor. Take the 5V 15 minute module as an example. If Uc = 2V, then time = 2V / 5V * 15 minutes = 6 minutes.
