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

Super low current draw. Doesnt get hot. Works perfect. I use it to switch on 2 car audio amps and 1 cooling fan.

An excellent SSR. When I first connected the SSR to my circuit it did not work properly. It wasn't the SSR's fault; it was my fault. I contacted the manufacturer with the description of the problem and a simple diagram of my circuit. Within a day I received a reply with suggestions on what to change in my circuit so the SSR would work. After a couple more email correspondences back and forth their tech support was finally able to educate me enough so I could get everything working. Customer support like this is very rare today. I can't say enough about the help I received; all I can say is thanks.

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

Great product. Worked perfectly.

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!

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.

Solid state relay (no clicking, fast switching) that hooks up directly to EPS32 / ESP8266 GPIO pin. It has a somewhat big form factor and comes in its own enclosure (however not watertight). The switch time will be quicker than a mechanical relay and the galvanic coupling will protect your ESP. However, a negative is that the output is only rated for up to 20V DC so you cannot use this to switch 110/220V mains.

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.

low loss SSR, ran at 5 amps no problem
