Enhance your timing control projects with this high-precision Time Delay Relay Module, powered by the dedicated NE555 timing chip for accurate and stable delay performance. Designed to operate reliably at a typical voltage of 12V DC, this module supports two switchable delay modes, adjustable timing, and features built-in protection for safe and efficient operation. Key Features: · Precise Timing Control: Utilizes the NE555 dedicated time chip to deliver a highly accurate and stable delay with a margin of just 1% deviation. · Dual Operating Modes: Easily switch between Mode A and Mode B using onboard jumpers — Mode A activates the relay immediately on power-on and disconnects after the delay; Mode B keeps the relay off initially and activates it after the delay period. · Adjustable Delay Range: Control the timing from 0.1 up to 5 seconds with the integrated adjustable resistor, providing flexibility for various timing needs. · Automatic Delay Start: The module begins timing instantly when powered on with no external trigger needed, simplifying integration. · Low Power Consumption: Consumes only 0.04W in standby and 1.0W during operation, featuring a standby current as low as 3mA for energy efficiency. · Anti-Reverse Protection: Built-in reverse polarity protection prevents damage if the power supply is connected incorrectly, ensuring module longevity and reliability. · High Load Capacity: Supports switching loads of up to AC 250V 30A or DC 30V 30A, suitable for controlling a wide range of electrical devices. · Output Configuration: Provides a relay output with one set of normally open (NO) and normally closed (NC) contacts for versatile wiring options. · Clear Indicator Lights: Equipped with red and green LEDs to visually indicate power status and relay operation respectively, enabling easy monitoring.
