The Story

4-Channel TLP281 Optocoupler Isolation Module for Arduino
✔️ 4 isolated channels, HV up to 24V, 500mA sink per channel, pack of 5

The four channel breakout uses the TLP281 optocoupler to deliver galvanic isolation between control logic and higher voltage loads. This makes it ideal for Arduino projects, DIY prototyping, and noisy environments where signal integrity matters.

✅ 4 channels isolated via TLP281 optocouplers for safety
✅ HVCC up to 24V lets you control higher voltage loads
✅ OUT1 OUT2 OUT3 OUT4 provide HV switching with 5.1K referential current
✅ IN1 IN2 IN3 IN4 connect to microcontroller with common GND
✅ Pack includes 5 x TLP281 4 Channel Optical Coupler Isolation Modules

💡 What is an optocoupler isolation module used for? It is handy for safely interfacing low voltage controllers with higher voltage loads. - galvanic isolation between control and load circuits for microcontroller projects - handy for protecting microcontrollers when switching 24V loads - uses TLP281 optocouplers for reliable performance - supports four independent channels for multiple signals
