Elecbee NE555 Time Delay Relay Module 12V Adjustable Timer Switch Board 0-10S 10A AC 220V Delay Control Module

The Elecbee NE555 Time Delay Relay Module is a 12V adjustable timer relay board designed for delayed power switching, automation control, industrial timing circuits, and embedded electronic applications. Built around the reliable NE555 timer chip, the module provides adjustable delay activation control for relays and connected equipment.

After power is applied, the relay output remains inactive during the configured delay interval. Once the preset delay time is reached, the relay activates automatically and maintains its operating state while power remains connected. The adjustable timing range supports approximately 0 to 10 seconds through onboard potentiometer tuning.

The relay module supports control of AC equipment up to 220V 10A, making it suitable for automation systems, delayed startup control, motor protection circuits, smart switching systems, and industrial timing applications. Integrated power and relay status indicators simplify installation, monitoring, and troubleshooting.

The delay timing can be modified through potentiometer adjustment or by changing capacitor values on the timing circuit. The timing formula follows the standard NE555 RC timing structure: T = 1.1RC, allowing flexible customization for engineering and electronic development projects.

Designed for reliability and easy integration, this module is suitable for embedded systems, DIY electronics, industrial automation, relay control circuits, and intelligent device timing control applications.
