Single Channel Relay Module Opto-Isolated 3.3V & 5V Logic 10A Load

The Relay 1 Channel Module (Opto-Isolated) is a compact, high-quality switching module designed for direct control via 3.3V or 5V logic systems such as Arduino, ESP32, or Raspberry Pi. Featuring an onboard 817C opto-isolator, the module ensures electrical isolation between the control circuit and the high-voltage load for safer operation and reduced interference.

Capable of switching up to 10A loads at 250VAC or 30VDC, it’s ideal for controlling motors, lights, fans, and other high-power devices. The onboard LED indicator provides clear relay status feedback, making it a reliable choice for DIY automation, robotics, and industrial control projects.
