7.Pin Space:2.54mm

8.Function:power on automatic reset,Vo output is open circuit;after delay for some time,Vo output port output high level.after Vi port input high level signal reset,Vo output port output open circuit;after delay for some time,Vo output port output high level.Or power on automatic reset,Vo output port will output high level;after delay for some time,Vo output port will output open circuit,Vi port input high level and reset,Vo output port will output high level;after delay for some time,Vo output port will output open circuit

Pin Definition:


2.Vo:output port

3.Vi:trigger signal input port (high level trigger)

4.GND:power ground

Using Method:

1.Delay time can be adjusted by potentiometer,range is 1s-20h

2.Vo output port can be set by wire jumper

  1,2,3 three pins are used to set timing time range,1-2 connection timing time is 1s-290s adjustable;2-3 connection timing time will enlarge 256 times,that is 256s-20.5h adjustable

  4,5,6 three pins are used to set module output port Vo state;5-6 connection,power on initial state and after reset output is high level;when timing time is over output is short circuit;4-5 connection,power on initial state and after reset output is short circuit,when timing time is over it will output high level

3.Anti-clockwise adjust potentiometer,time will decrease;clockwise adjustment potentiometer time will increase
