Widely used for Domestic appliance, office machine, audio, equipment, automobile, etc. ( Remote control TV receiver, monitor display, audio equipment high rushing current use application.) Power Supply : 5V Load Voltage : AC 250V 10A,DC 30V 10A Total Size : 134mm x 52mm x 17mm/ 5.3" x 2.0" x 0.7" (L*W*H) Mounted Hole Size : 3mm/ 0.12" Upper Mounted Hole Center Distance : 129.2 x 46.7mm/5.1" x 1.8"(L*W) Lower Mounted Hole Center Distance : 128.5 x 46.7mm/5.1" x 1.8"(L*W) Material: Electric Part Weight: 122g Notice : The input signal trigger mode is a low-level effective mode that ‘closes’ the normally open (NO) switch at low-level input. The advantages of a low-level drive, are the system power reset, the load will not work, and high security. ..................FAQ.................. Q1: Why some channels of the four-channel/eight-channel relay module do not work? A1: The relay module is triggered by a low-level voltage. The relay module requires nearly 70ma current per channel. This problem will occur if the power supply is insufficient. Please use a 5V/1A or higher power supply to power the relay module. Q2: Is the relay module a high-level trigger or a low-level trigger? What is the working voltage? What is the operating current? A2: This module is low-level triggered, and the current on the IO pin is less than 2ma when low-level triggered. The module is compatible with 3.3V TTL level, but the power supply voltage must be 5V, and the operating current of one relay is 70ma. Q3: Cannot insert the relay into the breadboard? A3: You have to bend the middle pin of the relay slightly to the right before you can insert it into the breadboard. ## Features - 5V Active Low Operation: This relay module operates at 5V and should not be powered by 3.3V, as it may not drive the relays effectively. 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 | 5,278 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 4 in Electromechanical Relays | | Brand | ELEGOO | | Coil Resistance | 125 Ohms | | Coil Voltage | 5 Volts | | Connector Type | Plug-In | | Connector type | Plug-In | | Contact Current Rating | 10 Amps | | Contact Material | AgCdO | | Contact Type | Normally Open | | Contact material | AgCdO | | Contact type | Normally Open | | Country Of Origin | China | | Current Rating | 40 Milliamps | | Current rating | 40 Milliamps | | Customer Reviews | 4.6 out of 5 stars 287 Reviews | | 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 | Plug In Mount | | Mounting type | Plug In Mount | | Operation Mode | Automatic | | Product Warranty | 1 year manufacturer | | Specification Met | CE | | Upper Temperature Rating | 85 Degrees Celsius | ## Product Details - **Connector type:** Plug-In - **Contact material:** AgCdO - **Contact type:** Normally Open - **Current rating:** 10 Amps - **Mounting type:** Plug In Mount ## Images ![ELEGOO Relay Module 4 Channel - Image 1](https://m.media-amazon.com/images/I/71HROTPwpsL.jpg) ![ELEGOO Relay Module 4 Channel - Image 2](https://m.media-amazon.com/images/I/717ENHbD9HL.jpg) ![ELEGOO Relay Module 4 Channel - Image 3](https://m.media-amazon.com/images/I/61fuene9IvL.jpg) ![ELEGOO Relay Module 4 Channel - Image 4](https://m.media-amazon.com/images/I/61xlMgfPGHL.jpg) ![ELEGOO Relay Module 4 Channel - 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.co.uk/products/48038731-elegoo-relay-module-4-channel](https://www.desertcart.co.uk/products/48038731-elegoo-relay-module-4-channel) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-08*
