The XY-J02 Single-Channel Relay Module is a versatile, programmable timing relay board designed for automated control of electrical devices. It combines a high-current relay with an adjustable delay timer and trigger cycle timing functions, 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 XY-J02 offers multiple operating modes to suit different timing requirements. The delay ON/OFF mode allows you to set a delay before the relay activates or deactivates after a trigger signal. The trigger 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-J02 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-J02 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, 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 mode — Use the onboard buttons to select the desired mode (Delay ON/OFF or Trigger Cycle) 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.

Q: What is the XY-J02 Relay Module used for?

It is a programmable timing relay for automated control of electrical devices, supporting delay ON/OFF and trigger cycle timing modes.

Q: What is the input voltage range?

The module operates from DC 6V to 30V, and also supports Micro USB 5V power input.

Q: What is the relay rating?

The relay is rated for 10A at 250V AC or 30V DC.

Q: What timing modes does the module support?

It supports Delay ON/OFF mode (delay before relay activation/deactivation) and Trigger Cycle mode (repeated on/off cycling at set intervals).

Q: How do I configure the timing?

Use the onboard buttons to select the mode and adjust timing values. The digital LED display shows the current settings.

Q: Does the module require an external programmer?

No. All configuration is done through the onboard buttons and LED display — no external programmer or computer is required.
