DC 12V NE555 Time Delay Relay Shield Timer Control Switch Adjustable Module Sec

Item Description

⏱️ 12V Time-Delay Relay Module — NE555 • 0–10 s Adjustable • 10 A

Delay the power-on of a load to prevent inrush current or staged start-ups (fans, amps, lights, car electronics). Simple potentiometer adjustment; LED indicators show power and timing.

🌟 Highlights

  • 🧠 NE555 timing controller — reliable, simple design

  • 🎛 Adjustable delay: ≈0–10 s via onboard potentiometer
    (extend the range by increasing the timing capacitor if needed)

  • 🔴🟢 LEDs: Power indicator + timing/trigger indicator

  • Output capacity: up to AC 250 V / 10 A or DC 30 V / 10 A (max load ≈ 2200 W at AC mains)

  • 🔐 Isolated relay output (NO/COM contacts) for easy wiring

📐 Specifications

  • Supply Voltage: DC 12 V (5 V version exists in market but not included here)

  • Function: Delay-ON (energizes relay after the set delay)

  • Controller: NE555

  • Quiescent Current: ~20 mA

  • Default Delay Range: 0–10 s (pot adjustable)

  • Board Size: 48 × 29 × 22 mm (approx.)

Note: Ratings are relay contact limits. For inductive or high-inrush loads (motors, transformers), use a snubber/RC or drive an external contactor/SSR.

🔧 Wiring & Use

  1. Power the module with +12 V and GND.

  2. Wire your load through the relay NO/COM terminals.

  3. Apply 12 V → Timing LED lights and counts down → relay closes after the set delay.

  4. Turn the trimmer clockwise/counter-clockwise to lengthen/shorten the delay.

    • Need longer delays? Replace the timing capacitor with a higher value.

🧰 Typical Applications

  • 🚗 Automotive electronics: staggered start to avoid ignition dips/inrush

  • 🔊 Audio/LED power: soft-start after PSU stabilizes

  • 🛠 Industrial/DIY: fans, pumps, heaters, stage power sequencing
