Review: Verpolungsschutzdiode kann Kurzschluß verursachen - Die Verpolungsschutzdiode liegt parallel zu VCC und GND. Verpolt man aus Versehen die Versorgungsspannung wird diese durch die Diode kurzgeschlossen. Das ist nicht Sinn und Zweck einer Verpolungsschutzdiode. Review: Great industrial component - It works as intended and keeps 24 and 5 volts isolated. Just realize that that the 5v output is normally closed circuit. so when 24 is applied, it opens the circuit. ## Features - Its working frequency is 20KHz,which can be used for signal isolation and polarity reversal. - It has a working status indicator and a power indicator,which can directly see the working status of the module. - It has a variety of different connection circuits. - It comes with a housing and can be mounted on rails. - SHOP WITH CONFIDENCE: To provide you with the highest quality service, If you have any question, please feel free to contact us.We will provide after-sales service until you are satisfied. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B6FPBKRP | | ASIN | B0B6FPBKRP | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 2.9 2.9 out of 5 stars (5) | | Customer reviews | 2.9 2.9 out of 5 stars (5) | | Date First Available | 16 December 2022 | | Date First Available | 16 December 2022 | | Item Weight | 118 g | | Item model number | 1 | | Item model number | 1 | | Manufacturer | DONGKER | | Manufacturer | DONGKER | | Package Dimensions | 9.09 x 8.79 x 3.99 cm; 118 g | | Package Dimensions | 9.09 x 8.79 x 3.99 cm; 118 g | | Part number | 1 | ## Images ![DONGKER 8-Channel Optocoupler Isolated Module, DC 24V to 5V PLC-PNP Signal Converter Voltage Converter Adapter Module - Image 1](https://m.media-amazon.com/images/I/61QbRNqvaUL.jpg) ![DONGKER 8-Channel Optocoupler Isolated Module, DC 24V to 5V PLC-PNP Signal Converter Voltage Converter Adapter Module - Image 2](https://m.media-amazon.com/images/I/51uEmMwhWaL.jpg) ![DONGKER 8-Channel Optocoupler Isolated Module, DC 24V to 5V PLC-PNP Signal Converter Voltage Converter Adapter Module - Image 3](https://m.media-amazon.com/images/I/61Bw6x24ABL.jpg) ![DONGKER 8-Channel Optocoupler Isolated Module, DC 24V to 5V PLC-PNP Signal Converter Voltage Converter Adapter Module - Image 4](https://m.media-amazon.com/images/I/61bj65zdIDL.jpg) ![DONGKER 8-Channel Optocoupler Isolated Module, DC 24V to 5V PLC-PNP Signal Converter Voltage Converter Adapter Module - Image 5](https://m.media-amazon.com/images/I/61aW43HKw2L.jpg) ## Customer Reviews ### ⭐ Verpolungsschutzdiode kann Kurzschluß verursachen *by M***F on 6 January 2026* Die Verpolungsschutzdiode liegt parallel zu VCC und GND. Verpolt man aus Versehen die Versorgungsspannung wird diese durch die Diode kurzgeschlossen. Das ist nicht Sinn und Zweck einer Verpolungsschutzdiode. ### ⭐⭐⭐⭐⭐ Great industrial component *by V***. on 16 July 2023* It works as intended and keeps 24 and 5 volts isolated. Just realize that that the 5v output is normally closed circuit. so when 24 is applied, it opens the circuit. ### ⭐⭐⭐⭐⭐ Keeps voltages separated *by M***G on 5 September 2023* Husband is using this device to keep the voltages separate so he doesn't burn up his Raspberry PI. It's been working very well for him. ## Frequently Bought Together - DONGKER Optocoupler Isolated Module,DC 24V to 5V 8-Channel Optocoupler Relay Module PLC-PNP Signal Converter - Optocoupler Isolation Module,DC 12V 24V 8-Channe Optocoupler Isolation Board PNP NPN Low High Level Output Signal Converter --- ## 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.tn/products/501678080-dongker-8-channel-optocoupler-isolated-module-dc-24v-to-5v](https://www.desertcart.tn/products/501678080-dongker-8-channel-optocoupler-isolated-module-dc-24v-to-5v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-28*
