Lots of options. - Nice relay board. Lo and Hi voltage systems are completely isolated. All 4 relays Hi voltage side are completely isolated from each other, which makes it very nice if you have system with multiple power systems. In my case I have 120VAC, 24VDC and 5VDC powers, so this works out real nice. Has jumpers to FLIP the inputs (Active lo or Active Hi) and all relays are 3-way and have both NO and NC function, so that adds extra flexibility. Built-in Back-EMF suppression circuit to protect your micro. Overall, very well made. Review: Just works! - Great 4 channel relay module for Arduino & Raspberry Pi. Includes a 5V in and ground screw terminal pair (marked as DC+ and DC-, respectively), along with four inputs for each channel. The relays all have optocouplers, transistors, flyback diodes, and LED indicators, so you don’t need to worry about adding those yourself. The opposite side of the board has Normally Closed, Common, and Normally Open connectors (marked as NC, COM, and NO respectively) for each relay. ## Features - It is 4 Channel Isolated 5V 10A Relay Module, each relay can individually switch on/off by an opto-isolated digital input, Standard interface can be directly connected with microcontrollers and be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, DSP, etc., very convenient. - Equipped with high-current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; Trigger current of opto-isolator: 5mA. - RELIABLE: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling isolation, triggering more reliable, more stable. - EASY to INSTALL: Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation. - High/Low level trigger can be selected by jumper. Very versatile, you can reverse the input logic with the jumper. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08PP8HXVD | | Best Sellers Rank | #86 in Single Board Computers (Computers & Accessories) | | Brand | ANMBEST | | Brand Name | ANMBEST | | Coil Voltage | 5 volts | | Connector Type | Screw | | Contact Current Rating | 10 A | | Contact Type | Normally Open | | Current Rating | 10 A | | Customer Reviews | 4.4 out of 5 stars 138 Reviews | | Item Highlight | Module for Arduino,Industrial use, stable performance, wide compatibility | | Manufacturer | ANMBEST | | Minimum Switching Voltage | 5 volts_of_direct_current | | Model | ANMBEST_MD314-319 | | Mounting Type | Screw Mount | | Number of Items | 10 | | Number of Packs | 2 | | Operation Mode | Off | | Part Number | ANMBEST_MD314-319 | | Unit Count | 2 Count | ## Product Details - **Brand:** ANMBEST - **Connector Type:** Screw - **Contact Type:** Normally Open - **Current Rating:** 10 A - **Mounting Type:** Screw Mount ## Images ![2PCS 5V 4 Channel Relay with Optocoupler High/Low Level Trigger - Image 1](https://m.media-amazon.com/images/I/81f9a7lXZjL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice relay.

One had some superficial damage to the jumpers, the other had a large gob of solder connecting the rightmost diode to the ground plane, so much so that it looked like someone sculpted the letter "Y" with it. I hit it with a bit of solder wick and it seems to function fine. Not a problem for me, but it would have possibly disabled the 4th relay for someone that didn't have the right tools to fix it. ## Frequently Bought Together - ANMBEST 2PCS 4 Channel 5V Relay Module with Optocoupler High or Low Level Trigger Expansion Board for Raspberry Pi Arduino - 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 - AEDIKO 4pcs DC 5V Relay Module 1 Channel Relay Switch Relay Board with Optocoupler Isolation Support High or Low Level Trigger --- ## 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.ni/products/264236354-2pcs-5v-4-channel-relay-with-optocoupler-high-low-level](https://www.desertcart.ni/products/264236354-2pcs-5v-4-channel-relay-with-optocoupler-high-low-level) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-11-02*
