{"title":"4 Channel 12V Relay Module BK_RL4_01","handle":"4-channel-12v-relay-module-bk_rl4_01","url":"/products/4-channel-12v-relay-module-bk_rl4_01","description":"This 4-channel relay module allows you to control up to four independent circuits using a microcontroller such as Arduino, Raspberry Pi, or other MCU boards. Each relay channel has an LED indicator that shows the current output state, making it easy to monitor which relays are active.\n\nThe modular design makes it simple to integrate into home automation, lighting control, and equipment switching projects. Each relay can switch loads up to 250V AC or 30V DC.\n\nKey Features\n\n\n4 Independent Channels – Control four separate circuits\n\nLED Status Indicators – Visual feedback for each relay state\n\nHigh Switching Capacity – Up to 250V AC / 30V DC\n\nTTL Control – Compatible with 5V, 12V, and 24V logic levels\n\nCompact Design – 50 × 70 × 15mm board\n\n\nSpecifications\n\n\nChannels – 4\n\nDrive Current – 20mA\n\nControl Signal – 5V / 12V / 24V TTL level\n\nMax Switching Voltage – 250V AC / 30V DC\n\nDimensions – 50 × 70 × 15mm\n\n\nIdeal For\n\nHome automation and lighting control\nEquipment and appliance switching\nArduino and microcontroller projects\nIndustrial control applications\n\n\nPackage Contents\n\n1× 4-channel relay module\n\n\n\nWarning: This module switches 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":4386,"title":"Default Title","sku":"EF-EF03007","price":21.66,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
