Product Overview

The LORDWORLD AT41 is a time delay relay module designed for timing control in electronic circuits. It operates across DC voltages of 3V, 5V, 12V and 24V with a maximum current of 1500mA. The adjustable delay range spans from 1 second to 20 hours. This module suits hobbyists and engineers building custom timer boards or delay switch applications.

Installation Notes

The module connects to a DC power source within the supported voltage range and the load attaches to the relay output terminals. Wiring must respect the 1500mA current limit to avoid damage. A common issue is supplying a voltage outside the 3V to 24V window or exceeding the current rating, which causes the relay to fail. The delay is set via the onboard potentiometer; verify the setting with a multimeter before final assembly.

Compatibility Check

Confirm your power supply delivers a stable DC output of 3V, 5V, 12V or 24V and can provide sufficient current for both the module and the connected load. Ensure the load does not draw more than 1500mA. Check that the required delay duration falls within the 1s to 20H range. The unit is listed as new condition and was first listed by the manufacturer in 2026.

Questions about this item

How can I verify the AT41 relay is timing correctly after wiring it to 12 V?

Apply power and measure the output switching interval; the module should hold the load for the set period between 1 second and 20 hours.

What comes with the AT41 module and what must I source separately?

The board itself is supplied; you will need a suitable DC power source (3 V, 5 V, 12 V or 24 V) and the load you intend to switch.

Which voltage version of the AT41 should I choose for a 24 V control circuit?

Select the 24 V variant; the module also exists in 3 V, 5 V and 12 V versions to match your supply.
