    SainSmart 8-Channel Relay Module

    - 5V 8-Channel Relay interface board, and each one needs 15-20mA Driver Current.

    - Equiped with high-current relay, AC250V 10A ; DC30V 10A .

    - Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) .

    - Indication LED’s for Relay output status.

    Fetures:

    A Relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits.

    - This 8 channel 5V relay has both optical and magnetic isolation, providing a lot of protection to the inputs from electrical faults on the outputs.

    - Works well with both 3.3V and 5V logic (Raspberry Pi, Arduino, Teensy..), requiring little current drive.

    - Breadboard friendly, using female/male dupont makes it extremely convenient for prototyping.

    - LED indicates its working status. Red refers to errors.

    - 3 terminals per SPDT relay.

    All of these features make SainSmart relay a great component for automation projects.

    Item weight: 0.3 pounds.

    12 customers mention12 positive0 negative

    Customers like the appearance of the relay. They say it looks good, they did a great job designing and creating it, and it's a pleasure just to look at. The layout is very nice and organized better than other relay modules they've seen. There are indicating LEDs and a nice set of solenoids.

    "...figured out what I want to do with this in the long run but it is very cool and I can see a lot of potential in it...." Read more

    "...So THANKS A LOT other reviewers! The layout is very nice and organized better than other relay modules I've purchased at hackerspaces...." Read more

    "...Looked exactly as the image provided. My board had little red leds to indicate the relay was on. Didn't expect it and it was very useful." Read more

    "Nice product, good value to add more capability to Arduino and interface it with real world items...." Read more

    7 customers mention7 positive0 negative

    "This made Raspberry Pi projects a whole lot easier and more fun...." Read more

    "...function to change if it negates or relays the input, makes this easy to play with." Read more

    "Not A Toy, But Really Fun To Play With!..." Read more

    8 customers mention0 positive8 negative

    Customers are not happy with the noise produced by the relay. They mention that it clicks audibly during a light show and that it's loud when working with lower voltage.

    "...Not a fault of the product, but they are very noisy, so for the "Christmas lights to music" purpose I had to place it in a box with sound proofing..." Read more

    "...This relay is kinda loud, so if you are working with lower voltage applications, I would suggest going with the solid state version...." Read more

    "...Note that because it's a mechanical relay, it's not exactly quiet...." Read more

    "...During a light show they click audibly, but outside in a controller box it shouldnt be too much of a problem." Read more

    Pretty good, but watch out for excessive driving current usage
    5 Stars
    Pretty good, but watch out for excessive driving current usage
    Even if the driving current for each channel is as low as 15 mA, driving 8 channels simultaneously may consume 120 mA and that is more than what a Pi or Arduino can handle. This module needs to be paired with a ULN2803A. Interestingly, a ideally mounted ULN2803A is available on Amazon!!Biggest complaint is that the wire connector holes are small. They will not accept more than one 10A wire, single or multicore. I could not daisy-chain power to the center poles of the relays. I had to solder a common power wire on the back of the device. Big pain.

    buen día amigos, con respecto al producto quedo muy satisfecho, todos funcionando a la perfección, se ve que es un articulo de buena calidad, muy bien fabricado y diseñados, real mente lo recomiendo, ahora con lo que estoy un poco molesto; (en la publicidad dice que viene en caja, es de cartón pero pues una caja para su protección, mis artículos llegan en un sobre y lo que real mente me molesto es que el sobre llego muy, demasiado maltratado, lo cual da la impresión de que no tienen ningún tipo de cuidado en la paqueteria y eso pudiera dañar el producto y de ser así lo molesto que es reportar algo dañado, por eso mi calificación de 4 estrellas )
