Beware that you need to hack the board to make it work with 3.3V devices, such as ESP32.The PC817 optocoupler input has both 4K7 resistor and 1.6V LED connected in series.With 3.3V input that results in optocoupler input current about 0.36 mA - too low.One way to make this work is to replace 4K7 resistor with 510 Ohm resistor.Which results in optocoupler input current about 3.3 mA.

I got these to operate 6A Peltier modules, and at anything other than near maximum duty cycle, the mosfets get extraordinarily hot (130C), even with added heatsinks.This is a fire hazard if not used with low current applications.

Como ya se comento; para hacer que funcione hay que eliminar el led azul y hacer un puente. Adicionalmente, también tienen fuga a tierra por lo que si conmuta un pequeño voltaje aprox 1.6 volts estando en reposo.Habría que revisar el modelo mas nuevo.Si te llego el modelo anterior regresalo.

I followed Nunyabiz very useful advice and shorted the INPUT LED. I my case I used my soldering iron to push off the led and bridged the two pads with solder. This worked! Ok, so it's pretty darn annoying that the vendor did not verify that the unit will not work at 3.3V on input with the LEDis in place; these re next to the optocoupler BTW! The output leds are fine as is.I expect the presence of these LED's causes enough of a voltage drop that 3.3V drops to the point that it fails to activate the MOSFET. Once I removed the input LED I was getting action below 3.3. Anyway, it is working now. I must say that this board works really well (the lack of a pair of extra holes on the board is a bit of a pain and a very odd design choice). That said, I really could not find anything quite as complete as this unit. I just wish I hadn't wasted a few hours on what turned out to be an LED Issue and many thanks to the post on how to fix this Nunyabiz. You saved me a lot of head scratching.One star deducted as a result of the LED/3.3V issue. Otherwise the response time on the board is excellent, the price is very reasonable and it's a well made and extremely useful board IMO. I had a heck of a time finding anything else and I am glad I went with this one.I'm using this little beauty to control a pump and a solenoid. I did not want to have to hand solder a MOSFET to protect my CNC controller board from the flyback current. Optocouplers eliminate the risk of frying delicate controller boards so use them! An optocoupler package is a lot cheaper than having to replace a new controller board

This product performs exactly as expected. I used it to amplify pwm signals from a PLC to operate hydraulic solenoid valves in a project I have been working on. This replaced very expensive proportional solenoid valve controllers, and it works well.

I needed a solidstate relay to isolate my 3.3v MCU from D12 220AC 40amp relays. This board worked great for my application. Each channel is isolated independently so needs both + and - wiring.One thing to Note: my MCU is exactly 3.3v and the power drop across the first Blue LED is significant enough to prevent the MOSFET from actuating. I'd suggest wiring with 5v MCU. However, I removed the (low voltage side) blue LEDs and bridged the pads with solder. And then it worked.
