Review: Work great - I've been using these [opto isolated relay modules] for years! Like being able to select Hi or Low triggers and, if necessary, isolate the board power from the relay drivers.
Review: 5V 4 channel relay board - Works as advertised. I do like the ability to change the control input from either a hi or lo signal to control the relays. Most only work with a hi control input.

### ⭐⭐⭐⭐⭐ Work great
*by P***6 on December 14, 2025*

### ⭐⭐⭐⭐⭐ 5V 4 channel relay board
*by G***F on September 5, 2024*

Works as advertised. I do like the ability to change the control input from either a hi or lo signal to control the relays. Most only work with a hi control input.

### ⭐⭐⭐⭐⭐ Use to switch Christmas lights this year
*by J***D on August 27, 2024*

Found these on Amazon to go with the Elegoo UNO R3 controller. The set that came in the "starter kit" had pins to activate the relays and that didn't seem to secure. These have screw terminals. These also have a high/low activation setting so you can switch the high/low back and forth. I would suggest that if you need relays, these will be a better choice.
