{"title":"2 Channel 12V Relay Module","handle":"2-channel-12v-relay-module","url":"/products/2-channel-12v-relay-module","description":"The 2-Channel 12V Relay Module allows you to control two high-power devices independently using low-voltage signals from a microcontroller such as Arduino. Each channel features an optocoupler-isolated relay with normally open (NO) and normally closed (NC) terminals for flexible switching configurations.\n\nDesigned for easy integration, the module includes indicator LEDs for relay status and screw terminals for secure high-voltage connections.\n\nKey Features\n\n\n2 Independent Channels – Control two devices separately\n\n12V Relay Coils – Requires 12V supply for relay operation\n\nOptocoupler Isolation – Protects your microcontroller from high-voltage feedback\n\nScrew Terminals – NO, NC, and COM connections per channel\n\nStatus LEDs – Visual indication of relay state\n\nLow-Level Trigger – Activate relays with a LOW signal from your microcontroller\n\n\nIdeal For\n\nHome automation and smart switching\nMotor and pump control\nLighting control systems\nArduino and microcontroller relay projects\n\n\nPackage Contents\n\n1× 2-Channel 12V Relay Module\n\n\n\nWarning: This module can switch mains voltage. Exercise extreme caution when working with high-voltage circuits. Ensure all connections are properly insulated and follow local electrical safety regulations.\n","vendor":"ElecFreaks","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":4368,"title":"Default Title","sku":"EF-EF03004","price":11.7,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
