This is a 12 V digital timer delay relay control module with a built-in LED display and adjustable timing. It is designed for automated ON/OFF switching of electrical loads based on a user-set delay — ideal for DIY automation, electronics projects, automotive control, lighting systems, and timer-based switching applications.
🔧 Key Features
-
Operating Voltage: DC 12 V (10 V–16 V range)
-
Digital LED Display: Shows timing/countdown clearly for easy setup and monitoring
-
Adjustable Delay: User can program delay time via onboard buttons (typical timing from fractions of a second up to long delays depending on module type)
-
Relay Output: Switches connected devices (lights, motors, pumps, fans, etc.) after delay
-
Compact Size: About 64.2 × 34.8 × 18.5 mm with protective shell/case
-
Control Modes: Supports simple delay ON/OFF and may include cycle/loop timing depending on version
📌 Typical Uses
✔ Light automation
✔ DIY electronics timing
✔ Automotive accessory control
✔ Irrigation or pump timer
✔ Motion delay circuits
✔ Smart home controller projects
🛠 General Specification Highlights
-
Delay Adjustment: Set via buttons on the module
-
Display Type: LED numeric display
-
Mounting: Snap-in or panel mount friendly
-
Switching Load: Relay contact for driving external circuits
Note: Always verify the load capacities before connecting heavy loads (motors, high-power lights, etc.).
🧠 How It Works (Quick Explanation)
You set the delay time using the buttons on the board. When power is applied (or a trigger signal is received), the module counts down the set time and then activates the relay output. This allows automated timed switching without microcontrollers or coding.
🔌 Example Applications
-
Control a LED strip or light to turn off after X seconds/minutes
-
Delay the start of a pump or fan
-
Create a programmable automation control for low-voltage systems
