XY-LJ02 1-Channel Delay Relay Module with LCD Display

The XY-LJ02 is a highly versatile, programmable 1-Channel Delay Relay Module designed for precise timing, cycle control, and automation tasks. Featuring a clear, easy-to-read LCD display, this module allows users to configure complex delay and timing cycles with ease. It supports multiple operating modes, including delay-on, delay-off, and infinite loop cycles, making it an indispensable tool for smart home automation, industrial control, and DIY electronics projects.

This module is engineered for flexibility, supporting a wide input voltage range of 6V to 30V DC, as well as a convenient 5.0V Micro USB power input. It features high and low-level trigger compatibility, allowing seamless integration with microcontrollers like Arduino, ESP32, and Raspberry Pi. With onboard UART communication, engineers can easily read and set parameters programmatically, ensuring high adaptability in advanced automated systems.

Features:

• Clear LCD Display: Displays the current mode, timing parameters, and status simultaneously for intuitive configuration.
• Dual Power Inputs: Supports 6V to 30V DC terminal input or 5V Micro USB power supply.
• Flexible Triggering: Supports both High-Level (3.0V to 24V) and Low-Level (0.0V to 0.2V) triggers, plus dry contact switch control.
• Wide Timing Range: Highly adjustable timing from 0.01 seconds up to 9999 minutes.
• UART Serial Control: Allows remote parameter configuration and status reading via TTL serial commands.
• Safety Features: Equipped with reverse polarity protection and emergency stop button (STOP key).
• Sleep Mode: Automatically turns off the LCD backlight after 5 minutes of inactivity to conserve power.
