Put this module in and working great. Would recommend for noise isolation and false triggers. Have 24 volt inductive sensors switching to 5 volts onto the arduino inputs through the module. ## Frequently Bought Together - 4 Bit Optocoupler Isolator, PLC Signal Level Voltage Converter Board Module (24V to 3.3V) - 4 Bit Optocoupler Isolator Module,PLC Signal Level Voltage Converter Board Module (3.3V to 24V) --- ## 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.it/products/706372662-dongker-optocoupler-board-4-channel-optocoupler-board-isolator-plc-24v](https://www.desertcart.it/products/706372662-dongker-optocoupler-board-4-channel-optocoupler-board-isolator-plc-24v) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-14*
