Not sure why bother with optocouplers as relays are 5v coil so would work on 5v Arduino outputs directly, but it all works correctly. The one thing which is not specified is these sink the 10mA or whatever, rather than source the output. You need to ground (logic low) the pins to actuate the relay. --- ## 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.is/products/69913250-5v-8-channel-relay-module-control-board-with-optocoupler-arduino](https://www.desertcart.is/products/69913250-5v-8-channel-relay-module-control-board-with-optocoupler-arduino) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-22*
