Supporting input voltages from 3.6V to 24V and output voltages up to 30V with a max current of 10mA, it features four independent channels with photoelectric isolation to minimize interference. Perfect for driving triodes, MOSFETs, and low-power relays, this module is a must-have for professionals seeking reliable, multi-voltage control in compact form. ## Description Parameter Drive terminal signal voltage: 3.6-24V. Output terminal voltage range: 3.6-30V (output current depends on the specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportional) Whether the output is a high potential output or a low potential can be realized by a jumper cap. The 4 channels 817 are separated., can achieve simultaneous control of different voltages, etc. Board size: 48mm x 38mm (length and width); long side hole distance: 42mm; wide side hole distance: 32mm Package Inluded: 1pcs NOYITO PC817 4-Channel Optocoupler Isolation Board ## Features - This module is used when it comes to the need for isolation control and voltage conversion. - Drive terminal signal voltage: 3.6-24V. Output terminal voltage range: 3.6-30V (output current depends on the specific situation but the maximum does not exceed 10MA, the total power is constant, the voltage and current are inversely proportional) - It can realize 3.3V or 5V to control the interface of 3.6-30V voltage . After the control terminal is turned on, the controlled terminal will also be turned on. - Photoelectric isolation has strong anti-interference ability. It can drive high-power triodes, MOS tubes and other applications that require high-voltage driving, and can also directly drive low-power 24V relays.If it is a pulse signal, please note that the limit of 817 is 4KHZ or less. If the control signal is greater than 4KHZ, please do not use this module, it will not work properly. - 【8-Channel Optocoupler Isolation Board ASIN ： B09RGTBDKJ 】 NOYITO PC817 4-Channel Optocoupler Isolation Board User Manual https://1drv.ms/u/s!AlzQUCOyZQhKgT98ibtG22R8W5eQ?e=VfKbrK ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | NOYITO | | Series | PC817 4-Channel Optocoupler Isolation Board | | Item model number | NOPC8174C | | Item Weight | 0.423 ounces | | Product Dimensions | 1.5 x 0.39 x 0.71 inches | | Item Dimensions LxWxH | 1.5 x 0.39 x 0.71 inches | | Color | Green | | Manufacturer | NOYITO | | ASIN | B07GMHLL2M | | Is Discontinued By Manufacturer | No | | Date First Available | August 19, 2018 | ## Product Details - **Compatible Devices:** Devices requiring isolation control and voltage conversion - **Connector Type:** Auxiliary - **Color:** Green - **Item dimensions L x W x H:** 1.5 x 0.39 x 0.71 inches - **Brand:** NOYITO ## Images ![NOYITO PC817 4-Channel Optocoupler Isolation Board Voltage Converter Adapter Module 3.6-30V Driver Photoelectric Isolated Module - Image 1](https://m.media-amazon.com/images/I/81N7AMe1eVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A great solution for dissimilar voltages *by J***D on December 7, 2023* I needed to interface a 12V alarm system into a component of my own design (5V). I wanted isolation and voltage conversion. This board worked fine.Some of the other reviews mentioned that grounds are connected together. This is true, and caused issues with interaction in my design. Wished that I could separate the Grounds. To solve this issue, I ordered the two channel version of the same optocoupler. In fact, I ordered a selection of the product with a selection of channels for future projects. I did find that if you use a number of these boards for I/O it can become quite a mess of wires. Nevertheless, they do a good job and I have found that they work through a wide voltage range.Great product. Recommended. ### ⭐⭐⭐⭐⭐ Voltage converter *by A***R on July 28, 2024* It was perfect for my application ### ⭐⭐⭐⭐ Not super clear info. *by E***R on May 22, 2023* Works fine but connectors are very finicky..the instructions could be clearer on configuration..also there is a 3 k resistor in series with the output v terminal so the actual isolated output v is going to depend on the load resistance. I used this as an emitter follower by removing the ground jumper... still not exactly clear on possible configuration and pull up pull down resistors. But works fine...leds built in is nice... ## Frequently Bought Together - NOYITO PC817 4-Channel Optocoupler Isolation Board Voltage Converter Adapter Module 3.6-30V Driver Photoelectric Isolated Module - NOYITO 1-Channel PC817 Optocoupler Isolation Module Optoelectronic Isolator Signal Isolation and Anti-Interference 3-5V 12V 24V (Pack of 2) (3-5V) - HiLetgo 3pcs TLP281 Optocoupler Isolation Board Optical Coupler Isolation Module 4 Channel Optical Coupler Isolation Module High/Low Level Expansion Board --- ## 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/91692842-noyito-pc817-4-channel-optocoupler-isolation-board-voltage-converter-adapter](https://www.desertcart.it/products/91692842-noyito-pc817-4-channel-optocoupler-isolation-board-voltage-converter-adapter) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
