A common end, a normally open end, and a normally closed end. ▪Optocoupler isolation, good anti-interference. ▪High Level or Low Level Trigger. The status indicator is on when it is engaged, and it is off when it is released. ▪VCC is the system power supply, JD_VCC is the relay power supply. Just plug in the jumper cap. ▪Power supply voltage: 5VDC ▪Current: more than 100mA ▪Load: 250V 10A AC or 30V 10A DC Wiring instructions: VCC: positive pole of system power supply GND: Negative pole of system power supply IN1--IN2: relay control port (Do not reverse the connection to avoid burning out) Packing List: 4 x 4 channel relay module 1 x 10pin F-M Dupont wire Review: They just work! - Great 4 ch relays for my Esp32 / raspberry pi projects. I have several of these in use and have help up for 1 year in harsh environment s without skipping a beat. I have had no defective units out of three separate orders. Review: Cheap, reliable, easy to use - I use these for work for years, and they never let me down. Soldering quality at times is not perfect, and a little bit noisy, but at this price point it's absolutely great product. ## Features - The power supply voltage of the relay module is DC5V. The maximum output load is AC250V 10A and DC30V 10A. - The relay has a standard interface and can be directly connected to the microcontroller, which is convenient for wiring. Package contains 10pin male to female DuPont wires. - High Level or Low Level Trigger. Pull in at low level and release at high level. The status indicator is on when it is pull in, and it is release when it is released. - The 4 channel relay interface board can directly control Arduino, AVR, PIC, ARM, PLC and other microcomputers, and can also control various high-current electrical appliances and other equipment. - Widely used in all MCU control, industrial fields, PLC control, smart home control. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C2Z8JF5R | | Best Sellers Rank | #160 in Single Board Computers (Computers & Accessories) | | Brand | Hosyond | | Brand Name | Hosyond | | Coil Voltage | 5 volts | | Connector Type | Dupont | | Contact Type | Normally Closed, Normally Open | | Current Rating | 10 A | | Customer Reviews | 4.5 out of 5 stars 56 Reviews | | Included Components | NO | | Manufacturer | Hosyond | | Maximum Switching Current | 10 A | | Minimum Switching Voltage | 5 volts_of_direct_current | | Mounting Type | Plug In Mount | | Operation Mode | Automatic | | UPC | 732214748170 | | Warranty Description | NO | ## Product Details - **Brand:** Hosyond - **Connector Type:** Dupont - **Contact Type:** Normally Closed, Normally Open - **Current Rating:** 10 A - **Mounting Type:** Plug In Mount ## Images ![Hosyond 4Pack 4 Channel DC 5V Relay Module with Optocoupler Relay Board for Arduino Raspberry Pi MEGA2560 - Image 1](https://m.media-amazon.com/images/I/71Homs1a1WL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ They just work! *by J***S on March 26, 2026* Great 4 ch relays for my Esp32 / raspberry pi projects. I have several of these in use and have help up for 1 year in harsh environment s without skipping a beat. I have had no defective units out of three separate orders. ### ⭐⭐⭐⭐⭐ Cheap, reliable, easy to use *by A***. on August 28, 2025* I use these for work for years, and they never let me down. Soldering quality at times is not perfect, and a little bit noisy, but at this price point it's absolutely great product. ### ⭐⭐⭐⭐⭐ Good product but be careful of the current draw *by R***O on August 4, 2024* The 4 channel relays work as advertised. While the pictures indicate that the module can be driven directly from an Arduino board, make sure it can source that much current on the 5V input. A typical Arduino Mega can provide a maximum of about 1W on it's internal 5V supply, which translates to about 200mA. But when all 4 relays are turned on, the 5V draw is about 280mA. Recommend that an inexpensive (external) DC to DC supply is used to provide the 5V to the relays instead of the Arduino board as was shown. Note that the relay board even has a pin which can be used to provide that external power once the jumper is removed. Gave it 5 stars though because it works just fine. Good value for the cost. --- ## 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.at/products/535092624-hosyond-4pack-4-channel-dc-5v-relay-module-with-optocoupler](https://www.desertcart.at/products/535092624-hosyond-4pack-4-channel-dc-5v-relay-module-with-optocoupler) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-22*
