Product Description:
The 1 Channel 12V Timer Relay Module is a highly reliable switching module ideal for precise timing control applications. Built around the popular NE555 timer chip, it allows users to control the relay ON/OFF timing via an adjustable potentiometer, offering a time delay range of 0 to 25 seconds. Designed with an optically isolated input, this module provides enhanced safety and stable signal triggering for automation, industrial control, or DIY electronics projects.


Key Features:

  • Wide Compatibility: Supports both high-level and low-level trigger signals.

  • Adjustable Delay Time: Fine-tune the relay delay from 0 to 25 seconds using the onboard potentiometer.

  • Optically Isolated Input: Ensures strong signal integrity and electrical isolation between input and control logic.

  • Powerful Relay Output: Supports high-power loads up to DC 30V 10A or AC 250V 10A.

  • NE555 Timer IC: Reliable and widely used timing chip for consistent delay performance.


Technical Specifications:

  • Operating Voltage: DC 12V

  • Delay Time: Adjustable 0 to 25 seconds

  • Relay Contact Rating: AC 250V / 10A, DC 30V / 10A

  • Input Signal: High or low pulse trigger

  • Optical Isolation: Yes

  • Relay Channels: 1


How to Use:

  1. Power the module with 12V DC.

  2. Provide a pulse input (high or low) to trigger the relay.

  3. The relay turns ON immediately after the input signal.

  4. Once the signal is removed, the timer starts.

  5. After the delay period (set by potentiometer), the relay turns OFF.

  • If the input signal stays active, the relay remains ON until the signal is removed.


Applications:

  • Delay switch control systems

  • Industrial automation timing control

  • DIY home automation

  • Signal triggering with delay function

  • Automotive electronics

  • Smart appliance control


Package Includes:

  • 1 x 12V Timer Relay Module (1 Channel, Optically Isolated Input)
