12v relay board Customers Reviews

  • Excellent! Works as suggested. Good isolation.

    posted by samborambo

    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 relay module for quality and price.

    I have spent some time using much more expensive computer controlled modules in the past that were similar to this but this one channel relay module beats them all for quality to price ratio. This single relay channel can easily be adapted to most computer interface to control remote things such as opening / closing a garage door, controlling lights and can also be easily controlled by an Arduino or Raspberry PI. Easy to configure and control with any most PC programs or with an Arduino.
    Great singlechannel domestic voltage control module. Including a one page manual of operation could be a welcome addition - for $.50 cents extra if needed.
    Excellent unit built superbe quality for its affordably low price.

    It is an original Arduino product. Good assembly and all inputs and output are labeled. It arrived safelly packaged in a bubble bag inside a carton box. Low price.
    I think that is a good buy.It can be useful for another electrical circuit, although arduinos
    I would buy another if i need it because of it reasonably price.You have the security that is an authenthic product.
