Adjustable Time Delay Relay Module

Optimize Your Device Control with Precision Timing

The Adjustable Time Delay Relay Module is designed for users who require precise control over their electrical devices. This module allows you to manage the timing of your equipment, ensuring that they operate safely and efficiently. Ideal for automotive applications and other electronic setups, this relay module prevents excessive current draw during startup, protecting your devices from potential damage.

Key Features:

• Compact Dimensions: Measures 6.8CM x 2.1CM, making it easy to integrate into various projects.
• Main Chip: Utilizes the NE555 chip for reliable performance.
• Dual Voltage Operation: Compatible with both DC 12V and DC 5V power supplies.

Functionality:

• Delay Mechanism: The relay does not engage immediately upon power connection; instead, it waits for a delay period of 1 to 10 seconds (adjustable). During this time:

– Normally open contacts are disconnected.
– Normally closed contacts are engaged.

• Adjustable Delay Time: Users can modify the delay time using a potentiometer or by changing capacitor values (e.g., increasing C1 extends the delay).

• Indicator Lights:

– Input power indicator light shows when the module is powered on.
– Relay pull-in indicator light signals when the relay has activated.

• High Load Capacity: Capable of controlling AC devices up to 220V/10A (2000W maximum), suitable for larger appliances.

• Protection Features: Includes freewheeling protection for added safety during operation.

Applications:

1. Ideal for automotive use where delayed activation can prevent damage from high inrush currents when starting multiple devices simultaneously.
2. Useful in scenarios requiring controlled startup sequences to avoid overloading circuits.
