4 Channel 5V Relay Module with Optocoupler

Description

4 Channel 5V Relay Module with Optocoupler is a versatile component used to control multiple devices with low-voltage microcontrollers like Arduino or Raspberry Pi. Here’s an overview of its features, specifications, and applications:

Key Features:

  1. Four Relay Channels:

    • Allows control of up to four separate devices, making it ideal for automation projects.
  2. Optocoupler Isolation:

    • Each relay is isolated from the control circuit, providing protection for the microcontroller from high voltage spikes.
  3. 5V Operating Voltage:

    • Designed to operate at a 5V supply, compatible with most microcontroller platforms.
  4. LED Indicators:

    • Often includes LED indicators for each relay to show its status (ON/OFF).
  5. Mechanical Relay:

    • Uses electromechanical switches to control high-voltage devices safely.
