The one channel relay delay timer board with USB and display is an electronic module designed for controlling the timing and switching of electrical circuits. It typically includes a relay for switching operations, a timer circuit for setting delay times, a USB interface for configuration or power, and a display for visual feedback of settings and operation status. This module is ideal for applications requiring timed control and automation in various electronic projects.

Relay Type: Typically features a single channel relay, often with normally open (NO) contacts. Delay Timer: Adjustable delay settings to control the timing of relay activation or deactivation. USB Interface: Allows for configuration, programming, or powering the board via USB connection. Digital Display: Provides real-time display of delay settings, countdown timer, and operational status. Trigger Input: Accepts trigger signals (e.g., voltage pulse, logic signal) to initiate the delay function. LED Indicators: Indicates power status, relay activation, and timing operation. Compact Design: Compact module size suitable for integration into electronic systems.
