uJPM ON-Delay Timer Switch Adjustable 12V (0.1 to 12 seconds) - (AD72087)

Description:

This is a 12V adjustable timer relay with a delay of 0.1 to 12 seconds. It is a very popular type of switch module. You can use it to control any device on or off. This is a 1-channel timer relay module controlled by DC12V. It has an NE555 timer chip on the board. You can adjust the delay time (0-12s) by turning the potentiometer. 

Operation: When the IN input is kept in a High state (12V), the countdown starts in 'n' seconds (according to the potentiometer setting). Once the set time has elapsed, the relay will activate and remain energized until the IN input switches to a Low state (0V).

The push button integrated into the module is an alternative to the IN input, meaning it is internally connected to this pin. You can choose whether to start the countdown with a 12V input on the 'IN' pin or simply by holding down the push button.

Features:

- Pin configuration: 

    - VCC: 12VDC max

    - IN: 12VDC max pulse input

- Delay time can be adjusted from 0-12s

- Increasing the potentiometer leads to an increase in delay time.

- Enlarging the capacitor leads to an increase in delay time.
