1.Delay Time Adjusting Range:1s-20h
2.Vo output port output high level driving capacity can reach 1500mA(short time allows 2500mA)
3.Power Voltage:DC 3-12V
4.Operating Current:3V---0.7mA;5V---1.4mA;12V---3.7mA
5.Note:when using the module,load negative connects with power negative,load positive connects with module Vo port.That is to say,controling load positive on/off
6.Application:relay switch,timer
7.Size:15*11*8mm (not include pin) pin space 2.54mm

Pin Definition:
1.Vcc:power
2.Vo:output port
3.Vi:trigger signal input port (high level trigger);
4.Gnd:ground

Function:
After power on,it will auto reset,Vo port output port open circuit;after some time delay,Vo output port output high level.Vi port input high level signal reset,Vo output port output open circuit,after some time delay,Vo output port output high level. Or power on reset,Vo output port output high level,after some time delay,Vo output port output open circuit.After Vi port input high level reset,Vo output port output highg level;after some time delay,Vo output port output open circuit.Above two modes can freely switch by module jumper

Using Method:
1.Delay time can be adjusted by module potentiometer,the range is 1s-20h
2.Vo output port level can be set by jumper
1,2,3 pin are used to set time range,1-2 connection timing range is 1s-290s adjustable;2-3 connection timing range is 256s-20.5h adjustable
4,5,6 pin are used to set module output port Vo state,5-6 connection,power on initial state and output after reset are both high level;when timing is over output opem circuit;4-5 connection,power on initial atate and output after reset are both open circuit,when timing is over output high level
Anti-clockwise adjust potentiometer,time will decrease;clockwise adjust potentiometer,time will increase

Package includes:

1PCS DC 3-12V Delay Circuit Module 1s-20h For Delay Switch Timer Precise 2.54mm
