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.
🧠 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
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.
Power the module with +12 V and GND.
Wire your load through the relay NO/COM terminals.
Apply 12 V → Timing LED lights and counts down → relay closes after the set delay.
Turn the trimmer clockwise/counter-clockwise to lengthen/shorten the delay.
Need longer delays? Replace the timing capacitor with a higher value.
🚗 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
