12V Adjustable Delay Timer Relay Module (2–5 Minutes)

Enhance your automation and control projects with this dependable 12V Adjustable Delay Timer Relay Module, built using the reliable 555 timer IC and a high-quality 12V relay. The module provides an adjustable delay timing sequence from 2 to 5 minutes using the onboard variable resistor.

When powered ON, the relay remains in its default NC (Normally Closed) position while the timer counts down. After the preset delay time expires, the relay automatically switches from NC to NO (Normally Open), activating the connected device or circuit. The relay remains active until the Reset Button is pressed, which cuts off the power supply to the connected load. An additional Enable Button allows the user to reactivate the power supply to the connected load after the system reset.

This timer relay module is ideal for:

• Automatic switching systems (e.g., alarm, LED light, AC Bulb)

• Battery and inverter protection systems

• Smart control applications

• DIY electronics projects
