New 1s ~ 20h Adjustable Delay Timer Module for Delay Time Switch & Relay
Time range jumper time ratio at two jumper positions (Pin 1&2 vs. Pin 2&3) is 256:1. Suppose we need a delay time of 8 hours, we can put jumper at 1 second - 290 second jumper position (pin 1&2), then adjust delay time to 8/256 = 0.03125 hour = 112.5 seconds. Then put jumper at 256second to 20hour position (pin 2&3).
This is a mini size but very useful delay timer control module.
It can be adjusted between a delay time of 1 second ~ 20 hours.
Please read below for detailed parameters.
Note: All parameters tested at 5V. May slightly fluctuate under other voltage.
Vcc: Power Input
Vo: output
Vi: Trigger-signal input (posedge trigger)
Gnd: ground of power input
Basic working mode and parameters:
1. Mode One: The module has automatic reset when power on. Vo gives low level. After delay for some time, Vo gives out high level signal. Vi gives out high level signal and reset, then Vo gives out low level, after delay for some time, Vo gives out high level.
Or
2. Mode Two: The module has automatic reset when power on. Vo gives high level. After delay for some time, Vo gives out low level signal. Vi gives out high level signal and reset, then Vo gives out high level, after delay for some time, Vo gives out high level.
The two modes can be switched to each other by switching jumpers on the module (please read on for details about jumpers)
3. Adjustable delay range: 1 second ~ 20 hours
4. Vo max output current is 2.5mA
5. Module Input: DC 3~15V
6. Module Working Current: 1mA
How to use the module:
1. Delay time can be adjusted by the potentiometer onboard. Time range 1 second ~ 20hours
2. Vo output level can be set with jumpers. Please refer to below diagram and explanation:
Pin 1, 2, 3:
The three pins are used to set delay time range. Pin 1, 2 together by jumper: for delay time range 1~290 seconds; Pin 2, 3 together: for delay time 256 seconds to 20.5 hours
Pin 4, 5, 6:
The three pins are used to set Vo output status.
Pin4,5 together by jumper: after power on, initial output when power on and output after reset are both high level, and when set delay time is reached, output turns to low level;
Pin 5,6 together: after power on, initial output when power on and output after reset are both low level, and when set delay time is reached, output turns to high level;
When we turn the potentiometer counter-clock-wise, time range narrows down. When we turn clock-wise, time range enlarges.
