Digital LED Cycling Time Delay Relay Module Key Features and Benefits Wide Operating Voltage Range: Supports DC 6V–30V power supply and TypeC 5V input for versatile compatibility with various power sources. Reliable Trigger Input: Accepts level trigger signals from 3V–24V with builtin optocoupler isolation, ensuring stable and interference performance. Strong Output Capacity: Handles up to 30V/5A DC or 220V/5A AC output, making it suitable for both lowvoltage and mainspowered applications. Low Power Consumption: Quiescent current of only 20mA and operating current of 50mA help reduce energy usage and heat generation. Wide Temperature Tolerance: Operates reliably between 40°C to 85°C (40°F to 185°F), suitable for harsh environmental conditions. Adjustable Timing Range Flexible time delay settings from 0.1 seconds to 999 minutes, continuously adjustable to meet different control requirements. Timing range selection is simple — set parameters in mode selection, then short press the STOP button to choose your timing preferences. Enable Mode Two operation modes for precise control: ON – Relay activates during the OP conduction time. OFF – Relay remains inactive. Quick mode switching by short pressing the STOP button in the main interface; the current mode briefly flashes before returning to the main screen. Sleep Mode Automatic display powersaving feature: LED display turns off after 5 minutes of inactivity to extend module life and reduce energy use. Wake up instantly by pressing any button.
