Vszerda XY-LJ02 Relay Board for Home Automation

The Vszerda XY-LJ02 is a time-delayed trigger timing switch relay board designed for home automatic control applications. It features an integrated LCD display for clear status monitoring and configuration. The unit operates on a 6-30V input range and includes a USB 5V power supply option for flexible installation. This gadget suits hobbyists and installers building custom automation projects.

Power Input Limits and Relay Count

The board accepts a DC supply between 6V and 30V, so it cannot be used directly with mains voltage or sources outside that window. The USB port provides a 5V rail only for powering the module itself, not for driving external loads. With two relay channels available, the device cannot switch more than two independent circuits simultaneously. Users needing higher voltage isolation or additional channels must look elsewhere.

Highlights

  • LCD display simplifies timing setup
  • 6-30 V input suits varied power sources
  • USB 5 V output powers low-voltage devices
  • Dual relay channels control two circuits independently

Questions about this item

Should I pick the 6 V or the 30 V supply for my project?

The board accepts any DC input between 6 V and 30 V, so choose a supply that matches the voltage your load already uses.

What does the 5 V USB output actually run in practice?

It provides a regulated 5 V rail that can power an MCU, a sensor board or other low-current 5 V logic while the relay switches the main load.
