The DC 6-30V Relay Module Trip Delay is a versatile, programmable timing relay board designed for automated control of electrical devices with delayed power-off, disconnect timing, and trigger delay functions. It combines a high-current relay with an adjustable timer circuit, making it an ideal solution for applications requiring precise time-based switching — from industrial automation to home automation and DIY electronics.

The module operates from a wide DC 6V to 30V input range, making it compatible with 12V and 24V systems, as well as battery-powered setups. It also supports Micro USB 5V power input, providing a convenient alternative power source for bench testing and configuration. The onboard high-current relay is rated for 10A at 250V AC or 30V DC, capable of directly switching lamps, motors, pumps, solenoids, and other loads.

The module offers multiple timing functions to suit different control requirements. Delayed power-off allows the relay to remain active for a set period after the trigger signal is removed. Disconnect timing enables the relay to deactivate after a specified duration. Trigger delay allows a delay before the relay activates following a trigger signal. These functions are configurable through the onboard buttons and displayed on the digital LED display.

The module features a digital LED display that shows the current time settings and operating status, making configuration straightforward. The onboard buttons allow you to adjust delay times, operating modes, and other parameters without any external programmer or computer. The screw terminals provide secure connections for power, trigger input, and relay output. The black relay designation indicates the relay housing color.

The module is widely used in industrial control, home automation, lighting control, motor sequencing, security systems, and DIY timing projects. Its compact form factor and simple operation make it suitable for both beginners and experienced users.

Whether you are automating a delayed lighting system, sequencing motors in an industrial process, or building a custom timing circuit, the DC 6-30V Relay Module Trip Delay provides a reliable, programmable solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.

Usage

Getting Started

  1. Connect power — Supply DC 6V–30V to the power input terminals, or connect Micro USB 5V for bench testing.

  2. Connect the trigger input — Wire your trigger signal source to the trigger input terminals.

  3. Connect the load — Wire the device you want to control to the relay output terminals (NO/NC/COM).

  4. Configure the timing functions — Use the onboard buttons to select the desired mode and set the timing values. The LED display shows the current settings.

  5. Power on and test — Apply power and trigger signal. The relay will activate according to your configured timing.
