NE555 Delay Timing Adjustable Switch DC Module Monostable Switch Delay Board Shield 010s 5V 12V DC Automotive Oscillation Relay Color Hw010a 12v Clear overview The NE555 Delay Timing Adjustable Switch DC Module is a monostable delay timer shield designed to generate a timed output when triggered. With an adjustable delay range from 0 to 10 seconds, it operates on 5V or 12V DC and uses an NE555 timer to drive an automotive oscillation relay. The variant shown is Color Hw010a 12v. Key benefits Simple, reliable singleshot delay: generate a controlled ontime for a connected load with a precise delay. Adjustable timing: easily set 0–10 seconds to match your application without modifying hardware. Versatile power options: supports 5V and 12V DC systems, enabling use in small electronics and automotivestyle circuits. Shield/module form for quick integration: designed to be used as a compact delay module in DC projects. Relaydriven switching: provides a convenient interface to switch highercurrent devices through the included oscillation relay. Clear identification: color Hw010a 12v variant helps you choose the correct version for your project. Key attributes Functionality: NE555 timerbased delay with monostable operation and adjustable timing (0–10 seconds). Power and voltage: operates from 5V or 12V DC systems. Output: includes an automotive oscillation relay for switching a connected load. Form factor: DC module shield suitable for integration into existing projects. Variant: Color Hw010a 12v. What is included or implied by the product A delay timing module built around the NE555 timer IC. A monostable configuration that provides a single timed output per trigger. A relay output suitable for driving a connected load within the module's design parameters. Compatible operation in 5V or 12V DC environments. Performance notes Timing range: adjustable from 0 to 10 seconds, suitable for shortdelay switching needs. Stability and repeatability: designed to deliver consistent timed output for common DC applications. Integration: intended as a shieldstyle module to simplify inclusion in projects requiring timed switching behavior. Two to three use cases Delayed relay activation for lighting: trigger the module to energize a relay after a set delay (0–10 seconds) to power a lighting circuit or indicator after a wakeup or event. Debounced or timed singleshot activation: connect a momentary switch to obtain a single, timed relay pulse, preventing multiple triggering and creating a clean on/off cycle. Timed actuator or signaling: use the module to activate a console indicator, alarm, or small actuator for a fixed duration following a sensor signal or user input. How this helps your project Reduces design complexity: provides a readytouse delay function without designing a timer from scratch. Improves reliability: NE555based timing offers a proven, widely supported approach for monostable delay applications. Increases flexibility: 0–10 second adjustable delay covers a broad set of straightforward timing needs in 5V or 12V DC environments. Notes for selecting and using Choose the Hwou10a 12v color variant when your application uses a 12V DC supply and you require the colorcoded version. Ensure the driven load is within the relay's switching capabilities and within the intended DC supply limits of 5V or 12V as specified by the module design. When wiring triggers and loads, follow standard DC module practices to avoid short circuits and ensure proper isolation between trigger and load circuits.
