Pin Definition:
1.VCC: power
2.Vo: output port
3.TG: trigger signal input port (high level)
4.GND: power ground

Side Pin Instructions for Use:
1) After power on, Vo output port has no output, after Vi port input high level signal trigger, Vo output port has no output: after delay for some time, Vo output port output high level. Above two modes can be shifted by module wire jumper
2) 1, 2, 3 three pins are used to set the timing time range, 1-2 connection timing time is adjustable from 1 second to 290 seconds; 2-3 connection timing time is expanded by 256 times, which is adjustable from 256 seconds to 20.5 hours.
The 4, 5, and 6 pins are used to set the state of the module output Vo.
3) 4-5 connected, the initial state after power-on and the output after reset are low level, the output is open state after the timing time is reached; 5-6 is connected, the initial state after power-on and the output after reset are open state, after the timing time is up the output is low.
4) Adjust the potentiometer counterclockwise, the time is reduced, and the potentiometer time is increased clockwise.
5) The timing time range jumper has a timing of 256:1 at two locations. Assuming an 8-hour delay, you can first connect the 1-2 pins with a jumper cap, adjust the delay time to 8/256=0.03125 (hours) = 112.5 (seconds), and then use the jumper cap to 2-3 Two needles can be connected. This greatly shortens the debugging time. The debugging process requires a self-contained stopwatch.

Note:
1. When using module, load negative connects with power negative, load positive connects with module Vo port; that is controlling load positive on/off.
2. The module has a protection diode and a power supply decoupling capacitor inside, which can be directly connected to an inductive load such as a relay. It is no longer necessary to connect a diode on the coil.
