Simple Adjustable Delay Relay Built Around the NE555

The Relay 12V Timer Delay NE555 Module is a compact delay-on relay board for projects that need a short timed switch action without adding a microcontroller. It uses the classic NE555 timer IC and an onboard adjustment stage to set the delay.

This is a good choice for startup delay, surge reduction, sequenced switching, and basic timed control in DIY electronics and practical automation jobs.

Important: Delay time is adjustable in the board range and can be extended by changing the RC values. The listing gives the formula T = 1.1RC for custom tuning.

Why you'll like it

  • NE555 timer core: Simple and well-known timing design
  • Adjustable delay: About 0 to 10 seconds on the board
  • Relay output: Useful for timed AC or DC load switching
  • Status LEDs: Easy power and actuation checking
  • Great for no-code timing jobs: No controller required

What you can build

Use it for delayed startup, overcurrent reduction, staged power-on, timed alarms, fan delay, and other short timing functions.

Starter bundles

Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus jumper wires, a suitable power supply, and a small load for bench testing.

Recommended add-ons

Useful add-ons include terminal block, breadboard, power modules, fuses, and enclosure, especially when you are working with higher voltages or inductive loads.

Frequently Asked Questions

Do I need Arduino to use it?
No. This is a stand-alone timing board.
Can I make the delay longer than 10 seconds?
Yes, by changing the timing components, as noted in the listing.
What happens when power is applied?
The relay waits for the set delay, then changes state.
