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
