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

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.

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.

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.

I was pleasantly surprised by this thing, clearly printed inputs/outputs and reliable performance and easy installation. The module's wide voltage range compatibility was a big reason I bought it. I highly recommend this module as it greatly enhances my projects and simplifies the relay control process.

This relay is bigger, and more expensive, than most common DC relays; but it is a much better choice for projects that involve a very low switch voltage, and a relatively high output voltage.

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.

This relay is fairly sturdy for something that is geared toward Pi or Arduino projects. It is a nice contained unit that is prewired to use in a microcontroller project. The diagram on the label is clear making it simple to setup. Overall this relay works well and is solidly built for a hobbyist project.
