8 channel relay Customers Reviews

  • Great relay board for the money

    posted by mrf604

    How can you go wrong? Eight relays for $14. I don't think you could even buy the relays as parts for that price. Then having the drivers, Screw Terminals and PCB included makes this an incredible buy. The Aruino easily drives the inputs. Each input has a transistor to turn on each relay. You drive the relays with a separate 5V supply. I measured the current from at the Arduino pin as 8ma. Each input on the relay board is represented by an LED. These LEDs turn on even if the Relay Supply is off.
    Seems to have fairly good quality relays.
    Another great buy!
  • Best for Home Automation

    Came well packed, It has an LED indicating power supply 5 Vdc, and 8 LED to indicate when the contact is closed. The descriptions are not in chinese!
    Remember buying some Male to Female jumpers (SKU: 146935) and to have a mini screwdriver for the tiny screws of the relays! Also take care working with high voltages and high currents! Try testing the contact with small voltages like turning on flashlights.
    Cheap, and versatile.
  • Excellent! Works as suggested. Good isolation.

    Very versatile relay board with isolated relay driver/buffer.Works with digital output voltages from 1.6V to over 12V.Ability to separate 12V (for relay driver) ground from your sensitive digital ground, eliminating noisy ground problems.10A resistive AC load switching.3A inductive AC load switching.12VDC power indicator LED and individual coil LEDs are a good feature for fault-finding.Excellent value. I wouldn't be able to find the components for this price.
    While this device is appropriate for use on AC mains switching, ***BIG FAT WARNING*** make sure you check the wiring rules for your country and get a registered electrician to check over your design and final wiring BEFORE you connect it to the mains.
    Bargain!
  • excellent board

    Plate very good to do projects and drives equipment using voltage higher than 5V, you can make a pretty cool automation to your home or anywhere else. Very good indeed she is well crafted welding is done well, really a product of first and besides the price is very cheap. Great build, easy to setup and come exactly as advertised. It is increbly cheap compared to the stuff that is packed into this products
    Comes packed in a cardboard box and a layer of plastic, all pins are perfect as well as the relays. everything ok
    I will do my drives home with this relay. I will continue buying more.
  • Good product at a very interesting price

    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.
