The XY-LJ02 DC 6-30V Single-Channel Relay Module is a versatile, programmable timing relay board designed for automated control of electrical devices with delay power-off, triggered timer, and cycle timing functions. It combines a high-current relay with a digital 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. 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 XY-LJ02 offers multiple operating modes to suit different timing requirements. Delay power-off mode allows the relay to remain active for a set period after the trigger signal is removed. Triggered timer mode activates the relay for a set duration when a trigger signal is received. Cycle timing mode enables the relay to cycle on and off repeatedly at user-defined intervals. These modes 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, cycle intervals, and operating modes without any external programmer or computer. The screw terminals provide secure connections for power, trigger input, and relay output.

The XY-LJ02 is widely used in industrial control, home automation, irrigation systems, lighting control, motor sequencing, 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 garden irrigation system, sequencing motors in an industrial process, or building a custom timing circuit, the XY-LJ02 Single-Channel Relay Module 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. Observe correct polarity.

  2. Connect the trigger input — Wire your trigger signal source to the trigger input terminals (if using triggered mode).

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

  4. Configure the timing mode — 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.
