Five-Piece Four-Channel Optocoupler Isolation Module With TLP281 ICs For Arduino Easy Low-Level To High-Level Control Four Channel Breakout Board For Isolated Switching HV Up To 24V Great For Prototyping And DIY Projects For Arduino Hobbyists

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
