Time Delay Switch Relay Module XY LJ02 Electronic Cycle Trigger Delayed Power-Off Circuit Board

This loop timing module features an LCD display for straightforward parameter monitoring and supports flexible high, low, and switch trigger signals for broad electronic applications. It operates on a wide voltage range of 6 to 30 volts or via a Micro USB connection, making it suitable for continuous timing and cycle control tasks. 1. Constructed from plastic with dimensions of approximately 8.0 x 3.8 x 1.9 centimeters, the compact unit includes a clearly labeled LCD screen that displays current modes and adjustable settings at a glance. 2. The module accepts input voltages between 6 and 30 volts or 5 volts through a Micro USB port, while its output capability allows direct control over DC loads up to 30 volts at 5 amps or AC loads up to 220 volts at 5 amps. 3. Users can independently configure operation time, off time, and cycle count parameters that automatically retain their values after power loss, alongside optional UART data upload for external adjustments. 4. Built-in hardware protections include an emergency stop button, reverse connection safeguard to prevent circuit damage, optocoupler isolation for signal stability, and a sleep mode that powers down the backlight after five minutes of inactivity. 5. Designed for routine electronics projects, the device supports seven configurable operating modes that handle single triggers, repeated cycles, retriggering intervals, and autonomous standby timing functions.
