NE555 DC 12V Delay-On Timer Switch Module Key benefits - Adds a reliable delay-before-on function to your circuits so loads activate only after a preset interval, simplifying automation and sequencing. - Built-in indicator LEDs make setup and troubleshooting fast: a power LED shows module status and trigger LEDs show when the delay/trigger is active. - High-quality design suitable for controlling AC or DC loads within the rated limits, reducing the need for additional timing circuitry. What it does - Delay-on timer module using the NE555 IC, powered by DC 12V. - When triggered, the circuit waits the configured delay time and then switches the output on. - Output can drive external loads directly up to AC 250V 10A or DC 30V 10A. Important attributes - Function: Delay-on timing (NE555-based) with visual indicators for power and trigger state. - Supply: DC 12V. - Output capacity: AC 250V 10A, DC 30V 10A (connect loads within these ratings). - Indicators: Power indicator LED and indicator LEDs for switch trigger status. - Installation: Connect a DC 12V supply and wire the output to the load keeping voltage/current within rated limits. How it solves problems - Prevents immediate activation of devices, enabling safe sequencing and reducing mechanical or electrical stress. - Visual LEDs reduce debugging time and make it obvious whether the module is powered and whether the trigger is active. - Offers a compact, single-module solution versus building a discrete timer circuit around the NE555. Typical applications - Delayed lighting: turn lights on several seconds after a trigger (motion sensor, door switch) to avoid false activations. - Motor or pump sequencing: start equipment after a delay to prevent simultaneous inrush or to allow upstream systems to stabilize. - Automation and control panels: integrate as a delay-on stage for relays, solenoids, or other loads within the specified AC/DC ratings. Safety and compatibility notes - Ensure connected loads do not exceed AC 250V 10A or DC 30V 10A. - Use the specified DC 12V supply. Follow appropriate wiring and safety precautions when switching mains voltages.
