Ensure the power supply current exceeds 1A for reliable performance. - High Current Handling: Each relay can handle maximum contact ratings of AC250V 10A and DC30V 10A, making it suitable for controlling various appliances and devices requiring high current. Working status indicator lights are conducive for the safety use. - Standard Interface: Features a standard interface for direct connections with microcontrollers — compatible with Arduino, Raspberry Pi, STM32, AVR, PIC, and ARM, allowing for easy integration into projects. - GPIO Low-Level Logic Control: This 4-channel relay module utilizes low-level logic voltage to drive the relays, which reduces power consumption and protects the control board from damage. This allows ESP32 and Raspberry Pi GPIOs to directly control the relays without the need for external transistors or logic-level converters. - Applications: Widely used for all MCU control, the industrial sector, PLC control, and smart home control. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XK6HCQC | | Best Sellers Rank | 4,384 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 3 in Electromechanical Relays | | Brand | ELEGOO | | Coil Resistance | 125 Ohms | | Coil Voltage | 5 Volts | | Connector Type | Screw | | Contact Current Rating | 10 Amps | | Contact Material | AgCdO | | Contact Type | Normally Open | | Country Of Origin | China | | Current Rating | 40 Milliamps | | Customer Reviews | 4.6 4.6 out of 5 stars (288) | | Included Components | 4-Channel Relay Module x1 | | Manufacturer | ELEGOO | | Manufacturer Part Number | EL-SM-006 | | Maximum Switching Current | 10 Amps | | Maximum Switching Voltage | 250 Volts (AC) | | Minimum Switching Voltage | 3.75 Volts | | Model Number | EL-SM-006 | | Mounting Type | Socket Mount | | Operation Mode | Automatic | | Product Warranty | 1 year manufacturer | | Specification Met | CE | | Upper Temperature Rating | 85 Degrees Celsius | ## Product Details - **Connector type:** Screw - **Contact material:** AgCdO - **Contact type:** Normally Open - **Current rating:** 40 Milliamps - **Mounting type:** Socket Mount ## Images ![ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino Projects - Image 1](https://m.media-amazon.com/images/I/71HROTPwpsL.jpg) ![ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino Projects - Image 2](https://m.media-amazon.com/images/I/717ENHbD9HL.jpg) ![ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino Projects - Image 3](https://m.media-amazon.com/images/I/61fuene9IvL.jpg) ![ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino Projects - Image 4](https://m.media-amazon.com/images/I/61xlMgfPGHL.jpg) ![ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino Projects - Image 5](https://m.media-amazon.com/images/I/71BnyZ61IdL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino UNO R3 MEGA Project 1280 DSP ARM PIC AVR STM32 Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ELEGOO UNO R3 Board for Arduino with USB Cable(Arduino-Compatible) More Faster In Transfer Rates And Better At Storage And Operation --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/48038731-elegoo-relay-module-4-channel-dc-5v-with-optocoupler-arduino](https://www.desertcart.nl/products/48038731-elegoo-relay-module-4-channel-dc-5v-with-optocoupler-arduino) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-08-20*
