For example, use the 3V or 5V voltage of a single chip to control the 9V or 12V voltage. HVCC should not exceed 24V - With four channels: This breakout board uses the TLP281 optoisolator and discrete transistors to correct the logic. Comes with four channels. Great for use in noisy circuits where signal lines require electrical isolation - Port: HVCC should not exceed 24V. Output port OUT1/OUT2/OUT3/OUT4 output current equal to HVCC/5.1K, sink current 500ma - Easy Operation: A normal LED opto-isolator will invert the logic of a signal. What you put into the IN pins, will be replicated on the the OUT pins, but at the higher voltage (HV) - Package includes: You will get 5 x TLP281 4 Channel Optical Coupler Isolation Module High/Low Level Expansion Board ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | DAOKAI | | Part number | WE-DA-094 | | Item Weight | 10 g | | Package Dimensions | 10.3 x 6.2 x 1.7 cm; 10 g | | Item model number | WE-DA-094 | | Colour | Optical Coupler Isolation Module | | Voltage | 24 Volts | | Plug profile | Plug-In Mount | | Included components | 5 x 4 Channel Optical Coupler Isolation Module High/Low Level Expansion Board | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Brand:** DAOKAI - **Circuit breaker type:** Standard - **Mounting type:** Plug-In Mount - **Number of poles:** 12 - **Manufacturer:** DAOKAI ## Images ![5 Pcs 4 Channel Optical Coupler Isolation Module TLP281 Chip IC Module Board Optocoupler Isolation High/Low Level Expansion Board, for Arduino - Image 1](https://m.media-amazon.com/images/I/712o47ZGAiL.jpg) ## Frequently Bought Together - DAOKAI 5 Pcs 4 Channel Optical Coupler Isolation Module TLP281 Chip IC Module Board Optocoupler Isolation High/Low Level Expansion Board, for Arduino - 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 - VooGenzek 120 PCS 2.54mm Breakaway PCB Board Pin Header Connector Strip Assortment Kit, Female Pin Header Socket Connector Strip, for Arduino Stackable Shield (4/6/8/10/12/16/20/40 Pin) --- ## 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/507962017-5-pcs-4-channel-optical-coupler-isolation-module-tlp281-chip](https://www.desertcart.it/products/507962017-5-pcs-4-channel-optical-coupler-isolation-module-tlp281-chip) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-11*
