Equipped with SMD optocoupler isolation, it guarantees stable, noise-free operation. The module supports both high and low level triggers selectable via jumper, includes power and relay state LEDs, and offers convenient screw terminal connections. Compact and mountable, it’s ideal for Arduino and home automation projects seeking reliable, professional-grade control. ## Description Module Description: The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA The module voltage 5V The module can be set high or low triggered by jumper Fault-tolerant design, even if the control line is broken, the relay will not operate Power indicator (green), relay state indicator (red) Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient Module size: 50mm * 26mm * 18.5mm (L * W * H) 4 mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm spacing Module interface DC +: positive power supply (voltage by relay requirements, 5V.9V.12V and 24V selection) DC-: negative one IN: can be high or low level control relay Relay outputs NO: normally open relay interfaces, relay before hanging, pull back and COM short-circuited COM: Relay Common Interface NC: normally closed relay interfaces, relay and COM short-circuited before, after the pull-vacan Review: works good but each channel is separate - need to add a jumper wire if you want to have both channels controlled by 1 input, but they work well and a bargain for the price - terminals are hard if you don't know to place wire to one side as the screw is in the middle. Review: Perfect for Arduino - I bought this item for my students and they used it in their Arduino circuits. Works very well with no complain at all ## Features - The module uses genuine quality relay, normally open interfaces - Maximum load: AC 250V/10A, DC 30V/10A - SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA - The module voltage 5V - The module can be set high or low triggered by jumper ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079FJSYGY | | Best Sellers Rank | #212,101 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #381 in Electromechanical Relays | | Brand Name | CHENBO | | Coil Voltage | 5 Volts (DC) | | Connector Type | Screw | | Contact Current Rating | 10 Amps | | Contact Material | Tungsten | | Contact Type | Normally Open | | Current Rating | 10 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (258) | | Manufacturer | CHENBO | | Maximum Switching Current | 10 Amps | | Maximum Switching Voltage | 250 Volts | | Minimum Switching Voltage | 5 Volts (DC) | | Model | WJ-00010 | | Mounting Type | hole mount | | Operation Mode | Automatic | | Part Number | WJ-00010 | | Wattage | 25 Milliwatts | ## Product Details - **Connector Type:** Screw - **Contact Material:** Tungsten - **Contact Type:** Normally Open - **Current Rating:** 10 Amps - **Mounting Type:** hole mount ## Images ![4 pcs DC 5V 1 Channel Relay Module Board Shield High/Low Level Trigger with Optocoupler - Image 1](https://m.media-amazon.com/images/I/71aGbUlrehL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works good but each channel is separate *by A***K on January 21, 2024* need to add a jumper wire if you want to have both channels controlled by 1 input, but they work well and a bargain for the price - terminals are hard if you don't know to place wire to one side as the screw is in the middle. ### ⭐⭐⭐⭐⭐ Perfect for Arduino *by F***D on December 3, 2022* I bought this item for my students and they used it in their Arduino circuits. Works very well with no complain at all ### ⭐⭐⭐⭐ Works with Raspberry Pi *by A***G on August 21, 2020* I'm using this with two Raspberry Pi boards (one a 3B+, the other a 2B) connecting both the 5V to power the solenoid board and using the PI 3.3V GPIO to turn on/off. One of the 4 units was defective out of the box but the others are working. For the money, they are a good choice. Note that there is a severe limit on the current available for GPIO switching from the Pi, so the single-channel model would be the only viable choice. I am able to use this to power a 3D printer on/off by switching the AC power using the OctoPrint PSU control add-in, which simply raises a configurable GPIO pin. ## Frequently Bought Together - 4 pcs DC 5V 1 Channel Relay Module Board Shield High/Low Level Trigger with Optocoupler - Micro Limit Switch, CYT1073 AC 2A 125V 3Pin SPDT Rocker Switches Long Hinge Lever for Arduino (30 Pack) by MUZHI - ACOSUN HJ Digital Servo Tester / ESC Consistency Tester for RC Helicopter Airplane Car --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/73684393-4-pcs-dc-5v-1-channel-relay-module-board-shield](https://www.desertcart.pl/products/73684393-4-pcs-dc-5v-1-channel-relay-module-board-shield) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
