  • 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.
  • high build quality

    posted by fnurkla

    Very good quality build. All the materials used in device are high quality: relays, board itself and connectors. It has a led for indicating power. Delivery package (a cardboard box) is also high quality. Easy-to-use relay board for an electronic project. Requres "standard" digital supply voltage 5V DC. Signal inputs accept 3.3V levels too because of on-board transistors. Small size and mounting holes allow to fit into required place.
    The relays are a bit slow so dont use this for high-performance requiring projects. Leds may be annoying if you use this for lightning projects, but you can easily desolder them.
    A good deal for DIY electronics to manage multiple external AC loads. Good soldering, and no flux residues...
  • Really good and cheap relay module

    posted by kasperk

    * Does exactly what you expect a relay to do* Works perfectly together with Arduino* Mounted on a small board which is prepared with mounting holes
    If you're the kind of person who builds a lot of projects using the Arduino platform or something similiar, you WILL need a bunch of relays sooner or later. Buy some and you won't regret it!
    Great relay module. Get a bunch now.
  • Good product at a very interesting price

    posted by Ferraldo

    The main advantage of this product is that the input is optically insulated. This is particularly relevant for me as I need to connect the board to an expensive National Instruments I/O board. Beside this, the product is cheap, compact, and reasonably well assembled. It has good connectors and useful status LEDs.
    The board is well packaged.
    Almost impossible to find this quality at this price.
  • Excellent value for money

    posted by Hendrik24051972

    This relay has an easy and understandable layout. It activates the relays on "high trigger", which I find useful for my applications.
    I wish I had bought the 8 Channel version instead of the 4 Channel. I'm using this one for 1 month, and I already have a destination for each of the 4 relays.I like this module, really works as designed.
    This is value for money. If you want relay functionality for your Arduino, then this is the relay-module you need.
