Relay Module 12V With Timer 555

This 12V Delay Timer Switch Adjustable 0-10sec is one kind of popular switch module. You can use it control any devices on or off. This is a DC12V controlled 1 channel timer relay module. It has a NE555 timer chip on the board. You can adjust delay time(0-10s) by rotating the potentiometer. When this relay get powered it will delay several seconds before relay turn on.

Note: recommended power + series with a diode to protect the circuit

Features:

• The relay will delay to close after connecting with the power supply
• The time of delay can be adjusted from 0-10s
• With relay current protection function
• Increase of the potentiometer leads to time delay increase.
• Enlarging the capacitor leads to time delay increase.
