Worked right out of the box and was simple to wire. Created a little 3D printed case for it to keep it clean and make it easy to mount. Review: signal isolation - received and tested works as advertised, just bought for stock for now. I use these to solve mechanical limit switch errors. ## Features - NOYITO 4-Channel Optocoupler Photoelectric Isolator Module Level Voltage Converter Module with high quality optocoupler and LED patch indicator. - The power supply has anti-connection protection.

Worked right out of the box and was simple to wire. Created a little 3D printed case for it to keep it clean and make it easy to mount. ### ⭐⭐⭐⭐⭐ signal isolation *by A***R on April 12, 2026* received and tested works as advertised, just bought for stock for now. I use these to solve mechanical limit switch errors. ### ⭐⭐⭐⭐⭐ Perfect for Arduino and Geckodrive G540 *by I***R on July 19, 2022* Works great to switch higher voltage logic signals with an Arduino. I'm using this on a CNC plasma cutter with an Arduino based torch height controller and Geckodrive G540. The G540 is powered by 24VDC and it's inputs are 12V logic active low. This module (5V->24V) allows the Arduino outputs to control the G540 inputs, and also provides an additional layer of isolation between the high voltage plasma source and the PC running Mach3 ## Frequently Bought Together - NOYITO 4-Channel Optocoupler Photoelectric Isolator Module Level Voltage Converter Module PLC Signal Converter Module PNP NPN to NPN (24V to 24V) - 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 - DONGKER Optocoupler Isolation Board,DC 3.3V 5V PNP NPN 8-Channel Signal Converter Opto Voltage Isolation Module --- ## 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.vu/products/523718280-noyito-4-channel-optocoupler-photoelectric-isolator-module-level-voltage-converter](https://www.desertcart.vu/products/523718280-noyito-4-channel-optocoupler-photoelectric-isolator-module-level-voltage-converter) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-14*
