This DC 12V time delay relay module provides reliable delay on and delay off switching for 12V circuits. It is designed to add timed control to a wide range of loads, enabling automated on/off actions based on a set delay. The module works with standard 12V control systems and is suitable for compact installations where space is a consideration. Key benefits Delayed turnon and delayed turnoff: schedule when the connected device powers up or shuts down to protect loads, reduce surges, or coordinate actions with other equipment. 12V DC operation: designed for 12V control circuits, making it easy to integrate with automotive, home automation, and low voltage systems. Compact and easy to integrate: small form factor that fits into tight enclosures and projects without adding bulk. Simple timing behavior: provides straightforward timerbased control to create predictable on/off actions without complex wiring. Reliable timing performance: built to perform consistently in standard 12V environments, helping automate routine tasks with confidence. Key attributes Functionality: delay on / delay off switching with a timer function for 12V systems. Compatibility: designed for use in 12V DC circuits and compatible with common 12V control setups. Size: compact board suitable for tight installations and DIY projects. Material and construction: built with standard components on a PCB suitable for timing relay applications. Performance: delivers stable timing control to regulate when a connected load turns on or off. What's included or supported A dedicated timing relay module that provides both delay on and delay off capabilities in a single unit. 12V DC power input to drive the timing and the relay operation. A straightforward interface suitable for integration into existing 12V control circuits. Applications and use cases Lighting control: implement delayed turnon for exterior or hallway lighting to reduce energy usage and avoid immediate on, or use delayed turnoff to provide a graceful shutdown period after an activation signal ends. Pump or motor control: use delay on to prevent motor inrush and reduce water hammer, or delay off to keep a pump running for a short period after control is released. HVAC or fan systems: delay off to ensure air handling equipment continues running for a short time after the control signal stops, aiding air distribution and component protection. This module aligns with standard 12V timing relay expectations, providing a practical, compact solution for adding timed delay functionality to a wide range of 12V circuits. It is suitable for hobby projects, automotive accessories, and small automation tasks where a simple, reliable delay on/off control is needed.
