Traditions (Generic) NE555 Timer Switch Adjustable Module DC 12V Delay Relay Shield 0~10S computer power cord

SKU CH-RYWH-H8SNQ

Adjustable NE555 timer relay module provides a 0 to 10 second delay at 12 volts DC

  • Adjustable timing from 0 to 10 seconds using the NE555 timer IC
  • Operates on a 12 V DC supply for standard relay control
  • Configurable delay suits custom power-sequencing needs
  • Compact relay shield format simplifies integration into existing wiring

Timer relay module for 12 V DC circuits

This adjustable module uses a 555 timer to provide a delay of up to 10 seconds. It suits hobbyists and technicians who need a simple time-delay switch for low-voltage projects. The board operates from a 12 V DC supply and fits basic automation or sequencing tasks.

Thermals noise and power draw

The small solid-state design produces negligible heat and no audible noise during normal operation. Current draw remains low, limited to the relay coil and timer circuitry at 12 V. No active cooling is required for typical intermittent use.

Questions about this item

How do I wire the NE555 timer module to a 12 V DC supply so the relay triggers correctly?

Connect the positive lead to the VCC terminal and the negative lead to GND on the module; the relay coil then switches after the 0~10 s delay you set with the onboard potentiometer.

Which part of the NE555 timer module is most likely to need replacement after extended use?

The electromechanical relay contacts wear out over many switching cycles, so the relay itself is the component you would eventually swap.
