DC 12V relay module with time delay function Key benefits Flexible timing control: Eight adjustable time ranges from 1 second to 1 hour, with both delay on and delay off options. This provides versatile control for powering devices on or off according to your schedule. Reliable protection: Builtin power reversal protection diode guards against reverse polarity, enhancing safety and extending the module's lifetime. Strong load capability: Suitable for switching devices up to 250V AC at 10A or 30V DC at 10A, providing ample performance for a range of appliances and systems. What it does Time delay function: A multi function timer integrated into a DC 12V relay module. You can set a delay before turning on or turning off the connected load, enabling precise control over power delivery. Compatible control and load: Operates with a DC 12V control input and can switch loads rated for up to 250V AC 10A or 30V DC 10A. Key specifications Input voltage: DC 12V Time delay ranges: 8 adjustable ranges from 1 s to 1 h Delay modes: Delay on and delay off Load capacity: 250V AC 10A or 30V DC 10A Protection: Built in power reversal protection diode Applications and use scenarios Lighting control: Use the delay on function to turn lights on after a set interval or with a delayed off to gradually reduce lighting at shutdown. Pump or fan control: Schedule startup or shutdown of pumps or fans to reduce electrical stress or create timed ventilation cycles. Automation sequencing: Implement safe sequencing in automation projects by delaying activation of downstream devices after the initial signal, or delaying deactivation to ensure smooth transitions. Reasons to choose this module It delivers precise timing with eight selectable ranges while offering the convenience of both delay on and delay off operations. The built in reverse polarity protection diode contributes to safer and more durable operation in real world deployments. Its load ratings cover a wide range of AC and DC devices, enabling practical integration into various electrical systems.
