Micro USB Timer Relay Module – 0-24s Delay, 5-30V Power for Automotive and DIY Projects

Technical Specifications and Application of Time Delay Relay Module (5-30V, Micro USB, 10A)

This time delay relay module with trigger control is a versatile electronic module for controlling timed switching of circuits and devices. It supports a wide DC input range of 5 V to 30 V, and can be powered via Micro USB or direct terminal connection, making it suitable for various automation and control applications.

Key Features:
✔ Wide supply voltage: operates on 5–30 V DC via Micro USB and direct power terminals.
✔ Adjustable delay time: delay can be set using an onboard potentiometer depending on user requirements.
✔ Trigger options: can be activated by an external trigger signal or by pressing the onboard button.
✔ LED indicator: built-in LED shows the relay activation status.
✔ Relay outputs: typically includes Normally Open (NO) and Common (COM) contacts.

How It Works:
When power is applied, the module waits for a “trigger” signal. Once triggered, the relay activates and stays on for the set delay time, then automatically deactivates. This allows precise timed control of lighting, alarms or motors without manual intervention.

Common Uses:
✔ Delayed power-on control for devices and equipment
✔ Time control of alarm lights, buzzers, and signal systems
✔ Automotive systems to prevent high start-up currents
✔ Automation and DIY electronic projects
✔ Educational electronics and prototyping

Benefits:

• Flexible timing control for many applications

• Easy power via USB or DC terminals

• Suitable for external and onboard trigger activation

• With visual LED feedback for easier debugging
