The 1-Channel Power Relay Module with Adjustable Timing Cycle is a smart delay relay controller designed to automatically turn loads ON or OFF based on a configurable time cycle. It integrates a high-power electromagnetic relay, onboard timing control buttons, and a digital display for precise delay configuration. This module is widely used in automation, pump control, lighting systems, motor control, and DIY timer-based applications where accurate time-based switching is required.
