By default, this 5V 4 channel relay module uses JD-VCC for relay power and is compliant with international safety standards, ensuring proper isolation between control and load areas through dedicated isolation trenches. The relay module 4 channel board is a convenient solution for controlling high-voltage and high-current loads such as motors, solenoid valves, lamps, and AC appliances. It is designed to interface easily with microcontrollers like Arduino, PIC, and other embedded systems. The relay terminals (COM, NO, and NC) are brought out via screw terminals for secure connections. It also includes LED indicators to display relay status. Features 4 independent relay channels for multi-device control 5V operating voltage compatible with microcontrollers Optocoupler isolation for safe and stable performance LED indicators for each relay status Screw terminals for easy wiring Supports both AC and DC loads High current handling capability (up to 10A) Compact and easy-to-integrate design Applications The 4 channel relay module, also commonly referred to as a relay module 4 channel, is widely used in automation and IoT-based projects. Whether you are using a 5V 4 channel relay module with Arduino or Raspberry Pi, it allows you to safely control high-power devices using low-voltage signals. Typical use cases include Switching mains loads Home automation Battery backup High current load switching Review: Product working - Best buy it without any tension value for money it is best in this budget it is best and it is very good in quality and very premium and fine finish buy it Review: Service delivery problem - The product is good but when I received it it's connectors were banded and it might be difficult to fix them ## Features - 4-CHANNEL RELAY CONTROL: Enables simultaneous control of multiple AC or DC devices, making it ideal for automation, robotics, and embedded switching applications. - 5V RELAY MODULE DESIGN: Operates on 5V input for seamless compatibility with Arduino-compatible boards, microcontrollers, and DIY electronics systems. - INTEGRATED OPTOCOUPLER PROTECTION: Built-in optocoupler isolation improves circuit protection and reduces interference for stable and reliable relay operation. - EASY MICROCONTROLLER INTERFACING: Designed for simple integration with Arduino and other development boards for quick setup in automation and control projects. - VERSATILE SWITCHING APPLICATIONS: Suitable for home automation, industrial control, smart devices, robotics, and electronic appliance switching projects. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07S29BN57 | | Best Sellers Rank | #2,049 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #23 in Robotic Kits & Accessories | | Brand | Robocraze | | Brand Name | Robocraze | | Coil Voltage | 5 Volts | | Connector Type | Screw | | Contact Current Rating | 10 Amps | | Contact Material | Silver | | Contact Type | Normally Closed | | Country of Origin | China | | Current Rating | 10 Amps | | Customer Reviews | 4.1 out of 5 stars 226 Reviews | | Importer Contact Information | TECHLEADS INDIA MO 7746071920 | | Included Components | 4 Channel Relay | | Item Type Name | 4 Channel relay | | Item Weight | 50 Grams | | Manufacturer | Robocraze, TECHLEADS INDIA MO 7746071920 | | Manufacturer Contact Information | TECHLEADS INDIA MO 7746071920 | | Maximum Switching Voltage | 5 Volts | | Minimum Switching Voltage | 5 Volts | | Model Number | RC-A-41526 | | Mounting Type | Screw Mount | | Operation Mode | Automatic | | Packer Contact Information | Robocraze 9902340705 | | Part Number | RC-A-41526 | | Specification Met | Energy Rating | | Unit Count | 1.0 Count | ## Product Details - **Connector Type:** Screw - **Contact Material:** Silver - **Contact Type:** Normally Closed - **Current Rating:** 10 Amps - **Mounting Type:** Screw Mount ## Images ![Robocraze 4 Channel Relay Module | 5V Optocoupler Relay Board - Image 1](https://m.media-amazon.com/images/I/61Wtiki1dUL.jpg) ![Robocraze 4 Channel Relay Module | 5V Optocoupler Relay Board - Image 2](https://m.media-amazon.com/images/I/61aXjFgneOL.jpg) ![Robocraze 4 Channel Relay Module | 5V Optocoupler Relay Board - Image 3](https://m.media-amazon.com/images/I/615Qcw+8bFL.jpg) ![Robocraze 4 Channel Relay Module | 5V Optocoupler Relay Board - Image 4](https://m.media-amazon.com/images/I/6148Un2zh7L.jpg) ![Robocraze 4 Channel Relay Module | 5V Optocoupler Relay Board - Image 5](https://m.media-amazon.com/images/I/61BgXnvV9uL.jpg) ## Questions & Answers **Q: Why the in1 to in4 pins have low level trigger. how to switch the pins to high level trigger ?** A: Low level trigger because of optocoupler used in module. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Product working *by H***Y on 12 July 2026* Best buy it without any tension value for money it is best in this budget it is best and it is very good in quality and very premium and fine finish buy it ### ⭐⭐⭐⭐ Service delivery problem *by M***S on 17 October 2025* The product is good but when I received it it's connectors were banded and it might be difficult to fix them ### ⭐⭐⭐⭐⭐ Good product *by R***T on 10 June 2026* I like the manufacturing of it ## Frequently Bought Together - Robocraze 4-Channel Relay Module Board | 5V Relay Module with Optocoupler for boards compatible with Arduino - Aptechdeals Jumper Wires Male To Male, Male To Female, Female To Female/ Breadboard Jumper Wires (40+40+40) --- ## 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.kg/products/126845113-robocraze-4-channel-relay-module-5v-optocoupler-relay-board](https://www.desertcart.kg/products/126845113-robocraze-4-channel-relay-module-5v-optocoupler-relay-board) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-08*
