12V DC Timer Delay OFF Relay Module 1-10s Adjustable 10A Push Button Switch

🔧 12V DC Adjustable Delay OFF Timer Relay Module 1–10s | AuscomTech

This compact electronic timing module provides automatic delayed switch-off control for electrical equipment and DIY automation projects. Featuring a microcomputer-based control circuit, adjustable 1–10 second timing and a 10A electromechanical relay, it offers a practical solution for applications requiring timed load activation.

Once powered, the module can be activated using its trigger input. The connected load switches on immediately and automatically switches off after the selected interval. The onboard potentiometer allows the operating duration to be adjusted without programming.

Designed for standalone operation, this controller is suitable for robotics, electronic product development, automation systems and time-limited equipment control.

⭐ Key Features

• Microcomputer-Based Timing Control – Electronic control circuitry provides stable and repeatable timed switching operation.
• Adjustable 1–10 Second Delay – Set the required operating duration using the onboard potentiometer.
• Automatic Delay OFF Function – Activates the connected load when triggered and automatically switches it off after the selected interval.
• 10A Electromechanical Relay – Supports switching loads rated up to 10A at 250V AC or 30V DC, subject to the connected load characteristics.
• External Trigger Connection – Allows operation using a compatible momentary push-button switch.
• Standalone Operation – Performs its timing function without requiring Arduino, ESP32, PLC programming or additional firmware.
• Potentiometer Adjustment – Simple manual timing adjustment without software configuration.
• Screw Terminal Connections – Provides convenient connections for the DC supply and switched load.
• Compact Circuit Board – Suitable for integration into electronic enclosures, control panels and automation projects.

⚠️ Important Notes

• Voltage Version: This listing is for the 12V DC version. A separate 5V variant exists, but the two versions are not interchangeable.
• Power Supply: Requires a suitable regulated 12V DC power source, not included.
• Timing Operation: The load switches on when triggered and switches off after the selected delay. This is not a delay-before-activation timer.
• Timing Accuracy: The specified range is approximately 1–10 seconds. Exact accuracy and resolution are not specified by the manufacturer.
• Trigger Operation: Use a compatible external switch. Direct activation using 3.3V or 5V microcontroller GPIO is not confirmed.
• Relay Output: The relay contacts act as an electrical switch and do not supply power to the connected load.
• Load Protection: Inductive loads such as motors and solenoids may require additional suppression and current derating.
• Electrical Safety: Mains voltage connections must be installed by a suitably qualified person using an appropriate protective enclosure and in accordance with applicable Australian electrical safety requirements.
• Operating Modes: The supplier specifies timed switch-off operation. Repeating cycles, programmable intervals and alternative timing modes are not confirmed.
