Key benefits Flexible timing control: adjustable delay allows precise timing before the relay activates. Wide power compatibility: works from 5V to 30V DC, powered via Micro USB for convenient power options. Simple integration: 1Pcs singlechannel relay module that can be added to microcontroller projects or standalone automation setups. Quick setup and testing: straightforward connections and triggerdelayed switching suitable for rapid prototyping. Reliable performace in compact form: a small, purposebuilt module suitable for compact enclosures and projects. Key attributes Functionality: delay relay timer with adjustable timing and triggerbased activation. Power and input: Micro USB powered, compatible with 5V30V DC sources. Channel count: 1 channel (singlerelay) on a compact board. Output: relay switch for controlling connected loads. Trigger behavior: designed to perform a delayed switch action following a trigger event. Form factor: compact module suitable for integration into small automation projects. Construction notes: standard module designed for ease of use in hobbyist and professional contexts; material details are not specified in the product title. Performance considerations Timing accuracy: adjustable delay provides configurable response times suitable for typical automation tasks. Reliability: built as a dedicated delay relay timer for consistent operation in projects requiring timed switching. Power versatility: compatible with power supplied through Micro USB within the 5V30V range, enabling flexible integration with controllers and sensors. Applications and use cases Delayed lighting control: connect a sensor or controller to trigger the module; after the set delay, the relay powers a light or LED strip for energyefficient, timed illumination. Equipment sequencing: use the delay to start a fan, pump, or other device after a sensor or controller event, enabling safe startup sequences or process timing. Home automation and prototyping: integrate with microcontrollers or automation systems to demonstrate delayed switching behavior for experiments or smallscale installations. Usage tips Ensure the input supply remains within the 5V30V DC range when powered via Micro USB. Configure the delay setting to match the desired timing before connecting to the load. Use appropriate wiring practices for the relay contacts to ensure safe operation with connected devices. Note This product is marketed as a Smart Electronics delay relay timer control module with 5V30V micro USB power and adjustable delay. It is presented as a 1piece (1Pcs) unit intended for singlechannel relay control and triggerdelayed switching in a variety of automation and prototyping contexts.
