4 Channel 12V Relay Module with Optocoupler

The 4-Channel 12V Relay Module with Optocoupler is an essential switching board designed for controlling up to four high-power devices simultaneously. Operating on a stable 12V supply, this module allows your low-voltage microcontrollers to safely switch heavy AC or DC loads without the risk of electrical damage.

Equipped with dedicated optocouplers for each channel, this board ensures complete electrical isolation between your control logic and the high-voltage outputs. It is a staple for DIY robotics and is highly compatible with a wide range of microcontrollers, including Arduino, ESP8266, and ESP32 systems. Whether you are building an automated smart home system, engineering custom warehouse automation, or designing a complex circuit diagram, this module is the perfect choice to buy online in India for reliable and safe power management.

Features:

• Four Independent Channels: Control up to four separate high-power circuits from a single microcontroller board.
• Optocoupler Isolation: Built-in opto-isolators on every channel protect your logic circuitry from voltage spikes and feedback.
• High Switching Capacity: Each relay can safely handle AC loads up to 10A at 250VAC or DC loads up to 10A at 30VDC.
• Visual Status Indicators: Features onboard LEDs to indicate power status and individual relay activation, streamlining your troubleshooting process.
• Robust Terminal Blocks: High-quality screw terminals ensure secure and stable wiring for high-current applications.
