  • Great relay module for arduino

    posted by marekdsk

    Product is small, clearly marked pins. Relay are isolated with optocouplers, which is great, because it does not get any interference. It has leds to show, which relay is in switch state. It is as good as any another, if I will need any more, I will sure buy more. Thank you
    Product is ok, but some people, who dont have any experiences may find it difficult to use, because of missing manual.
    It is good product, which I used on my model railway (controlled by arduino from DX too). It is fast responding, fully compatible for use with arduino. If I will need more, I will order some. Thank you DX. By the way, sorry for my english, it is not my native language.
  • 2 Channel 5V High Level Trigger Relay Module for Arduino

    posted by Troncs

    The value is low compared with other modules of the same segment, ie 5v input with 2 relay, 28v to 250v supports in a strain of 10A.
    Can be used with a switch in parallel. Easy installation for aqules who has basic knowledge of electronics and arduino. This relay will serve 95% of the projects, taking due attention to the engines pscina.
    Plate of red and blue relay. The circuit comes with an opto-isolator which very important for this type of connection.
  • Easy to use

    posted by amigueti

    Very easy to use. A good option for people who want to start with domotic services. A good option for people who are using a Raspberry Pi like me.
    Very nice for the price. Everyone who likes working with low cost electronic should give it a try. Very nice presentation. Leds make us know if everything is working ok.
    Happy for the bought.Resumen para los hispanos:Producto de buena calidad a un bajo precio. Los tiempos de envío son francamente buenos. El sistemas es una buena opción para usuarios de Raspberry Pi o Arduino. Incluye 3 leds para indicarnos el estado de funcionamiento.Estoy bastante contento por la compra.
  • Good for Proto and maybe production

    posted by TimTheEngineer

    - Includes screw through mouts for mounting to a chassis or project board- Very cheap to include two relays, PCB, headers, and driver circuits.- Very simply wiring because of screw terminals- Does come in a small anti-static bag
    If you can run a meter and need a simple 2CH relay circuit you would be hard pressed to build this for less not to mention the time it would take.For a Proto it's a no brainer, buy two.
  • Solid piece of kit

    posted by mattura

    A good quality build, which is solidly constructed. There are LEDs to show power and when each relay is switch on. It has a nice 'click' when the relays toggle. It works out of the box with arduino nano and other devices I'm sure. You can connect to outputs Normally Open or use the other slot for Normally Closed
    Also good that four screw holes are drilled to attach it to something.
    A good cheap set of 4 relays, easy to connect and use.
