Overview

Product Overview

The ShillehTek 8-Channel 5V Relay Module lets your Arduino or Raspberry Pi control up to eight devices independently, acting like eight electronically controlled on/off switches in one board. It is perfect for home automation panels, multi-zone lighting, pumps/solenoids, irrigation prototypes, test rigs, and any project where you need to switch multiple loads from GPIO signals. Each channel can be triggered from a control pin, so you can build clean, scalable automation without wiring eight separate relay boards.

What's included

Features & Specs

8 Independent Outputs Control up to eight separate devices with individual relay channels.

Great for Automation Perfect for multi-zone lighting, pumps, valves, and DIY control panels.

Arduino + Raspberry Pi Ready Trigger each channel using simple GPIO signals and basic code.

Clean Multi-Load Wiring One board simplifies wiring compared to multiple single-relay modules.

Expandable Project Friendly Ideal when your build is growing and you need more controllable outputs.

8 Channel Power

all the relay channels work as expected!

Works as designed.

Simple easy to use device. All the relays worked. Not much more you can ask for.

Works, seems pretty good.

Seems to have advanced stealth technology. (Not really, but it's amusing, but which will not play into my review.)These are 12V relays which means that you need to supply 12V to them. I tested with lower input voltage and it did not work. The relays can either trigger high (Height on the board) or low. It comes with 8 jumpers, which were on my board set to high trigger.The isolation seems pretty decent. With the optoisolators, and the board design, (There's a cutout around the common of each relay, I think it should be fairly safe as setup, as long as you don't like put it in a metal box and allow contact. I would say both AC and DC should be good.)There's one hangup that's purely aesthetic, which is that 7 of the 8 are in a nice line, and setup well. However, the 8th is high on one side. Argh!Tested all of the relays and they all work. The PCB seems decently made though the LEDs seem a bit off and there's that one relay. (If it annoys me tomorrow, I may just hit it with the hot air gun and deal with it.)The relays are Songle SRD-12VDC-SL-C, 10 A AC (@125/250VAC) or DC (@28V/30V DC) (Not sure why they marked the lower voltages on them, as it's the current that matters below the max switched voltage. So if you weren't aware, that's 10A @ 0VAC-250VAC, or 0VDC-30VDC)My plan is to use this to control some 12V automotive systems so it should be good for that. Haven't decided on a pi or something else (esp/arduino), but either will be able to use this.Overall, despite the aesthetic issue, I give it 5/5 as everything seems good. If that changes I'll update the review.-----Story time. This thing somehow has some advanced optical camo, because unless it's in my hands it basically ceases to exist. First time I lost it, it was right under/behind a camera and I just couldn't see it. Then I dropped it into a box, several subsequent times I've put it next to testing stuff it's just blended in. I can't explain it, it should be visible easily with the blue relays and red pcb. It somehow just vanishes. You can be looking at it, and won't see it! Somehow this is leaked Martian stealth composites, err wrong universe. Like 6 times today! But somehow, despite that, I'll never unsee the uneven relay!

Works as expected, sturdy board, well labeled

I've tried several Shillehtek products and been happy with them. This relay package is no exception. The board is sturdy, and well labeled. There is one typo where high is spelled heigh, but that happens in translation sometimes. I powered up the board and was able to trigger the relays as expected. You can use high or low triggering and that is set by individual jumpers for each relay. I'm happy with this device.

necessary to protect the Single Board computer when controlling other electronics.

I ordered the "8-Channel 5V Relay Module – High & Low Level Trigger Relay Controller Board" but got the 4-channel relay instead so I am doing the review on the 4 channel relay. This module is necessary when interfacing/controlling different pieces of equipment that are powered with a different voltage. The circuit board is clearly marked for both input and outputs and how to change the trigger from a low level to a high level. There is a pwr light that shows power is connected to the board and has 4 mounting holes that facilitate mounting the board on a stable item.It does its job and seems to be quality made.

Works, needs 12v power, PCB is a bit rough, kinda cheaply made but works.

Board is a little rough, edges fraying fiberglass, lots of flux left on the board underneath (see photo), and occasional mis-translations on the silkscreen (example: "high" logic level labeled as "height"). The requirement for 12v isn't great for a lot of projects as you'll need a second supply but might be helpful for something like automotive use maybe? Tested all channels with a 3.3v signal and everything works like I'd expect. Each channel has a TWS354 isolator which is a nice touch.
