Wired DC-DC 10Amp Isolated Solid State Relay Module, SSR in 3-32VDC Out 5-30VDC, for Raspberry-Pi Arduino ESP32 PLC MCU DSP

Great relay! Using with Konnected to power piezo with an external power supply. A little larger than desired but solid state is key!

Does EXACTLY as advertised, and BETTER! Very minimal amperage loss through the relay runs LED lights perfectly! They are just as bright as when wired directly to a 12V battery (three other SSRs failed miserably). Excellent quality, I’m pleased!

This works great. Using this to trigger an on-air light from a Wheatstone blade. I don’t know how else you talk up a relay but I will be buying more of them.

OONO’s DC to DC solid state relay is a nicely packaged module with a 10 A average current rating for an output voltage between 5 and 30 VDC. The secret to the high current rating without a fan or heatsink is the low-maximum on-state resistance of 0.008 ohms of the MOS output switch.It can be used with any microprocessor GPIO pin that can source ~ 6 mA and has a VCC of 3 VDC or more, or with other input signals that have a voltage up to 32 VDC. It uses opto-isolation to provide 5000 V separation between the input and the output circuits.In testing, I ran the module using an Arduino Uno (Vcc = 5 VDC) as the input with a duty cycle of 50%. I used a 10 ohms load and an output voltage of 30 VDC. The module handled the max 3 A current (average I = 1.5 A) without any issues. I then left the input pin on all the time for an average current of 3 A. This was the highest load condition that I could test easily, due to the limits of my power supply. The module had no issues with the load or the 30 volts power supply.This is a well-made module that can allow your microprocessor to switch high current and/or high voltage DC loads.

I have a CNC Router Machine which came with an underpowered spindle. I was planning on purchasing a small palm router to replace the spindle, since I also have an adapter for attaching the router to the machine instead of the spindle. Before purchasing the new router, though, I decided to first get an idea of how well such a setup would work. I already have a battery powered palm router that happens to be physically the same size as the one I was going to buy, so I mounted that on the machine and gave it a try. And wow, what a difference between the router and the underpowered spindle! It cut deeper per pass and quicker than the spindle ever could! So now I'm thinking of just using that and letting it take me as far as it can.The only problem is, I am limited to only relatively short jobs, because I don't want the battery to deplete before a longer job is finished. This is exactly why I ordered this Oono solid state relay - so I can replace the battery on my router with a separate DC power supply, controlled by the controller board of my machine via this relay. With the relay's 10A current rating, I think that will be about twice what the router's motor actually draws. I already have an external DC power supply that will give me the current and voltage that I need - I just have a little work left to do to make it all happen, such as confirm that the router doesn't actually draw MORE than 10A (I doubt it), and design and 3D-print an adapter that will take the place of the battery and provide the contacts that the router needs to operate.In my case, I had a specific purpose in mind for getting this relay, but it is also great for directly using a microcontroller such as Raspberry or Arduino (along with a proper power supply) to control DC devices of from 5 to 30 volts which draw much higher currents than the MCU could handle by itself. Great for experimenters, students learning about robotics or microcontrollers, makers, artists, hobbyists, etc.

This Solid State Relay is nice in the respect that it will work with a wide range of voltages, so in my applications it will work fine at 3.3 volts or 5 volts. Knowing that things like this are frequently over rated, I wouldn't expect this to last too long if I actually used it at 10 amps for any length of time, but it would probably handle 10 amps on a low duty cycle. While this is bigger than a small traditional relay, you get a lot of benefits from a solid state relay, like super fast switching times, and no points to wear out. If you need a solid state DC relay, then this one will do the job for you.

Very nice off the shelf Optically Isolated Solid State Relay – perfect for Arduino ProjectsIf you know electronics you can quickly build this circuit out of a few components. However, sometimes it is convenient to buy a ready made off the shelf module. The circuit is protected inside a box and the input and output Vcc supply wires and the load wires are already attached – read to go right now -. One of the reviewers was unfair in their criticism because they did not understand the electronic parameters. The Turn On input voltage signal and output voltage and current range are clearly provided in several places in the website description and in an annotated schematic diagram label right on the face of the product itself.

The box is bulky---much larger than a relay. But it is easy to interface with a microcontroller because the input minimum goes down to 3VDC. The LED indicator is nice so you know when it's activated. I don't know if I would trust it up to the full 10A, but would derate it to 50%. Perfect for controlling a large-current load with an ESP32, Pico or any other low-voltage source.
