  • Relay shield format enables direct integration with microcontroller projects

Adjustable 0~10S Delay Module

This DC 12V delay relay shield uses an NE555 timer to provide an adjustable switching delay from zero to ten seconds. It suits hobbyists and engineers who need a simple time-based control for low-voltage circuits. The module activates a relay after the set interval, making it useful for staged power-up sequences or automated switching tasks.

Sustained Load Behaviour

Under continuous operation the NE555 timer maintains its configured delay without drift caused by brief voltage fluctuations. The relay contacts are rated for the stated 12 V supply, so extended duty cycles do not introduce timing errors beyond the component's specified tolerance. Heat buildup remains low because the timer draws minimal current while the relay coil is energised.

Questions about this item

How much power does the NE555 timer module draw when it runs continuously on a 12V supply?

The module operates from a 12V DC source and uses the low-power NE555 timer IC, so its continuous current draw is minimal.

What external parts are needed to make the relay shield switch a load?

You need a 12V DC power source, the load you want to control, and wiring to connect the relay’s common, normally-open and normally-closed contacts.
