Essential Info

If you need a relay whose features include positive (+) or negative (-) trigger input, heavy duty contact rating, and on board LED status indicator, this is the unit for you! Two relays on one board, both triggered by one input. Since the relay outputs are independent of each other, you can use one to switch low voltage and the other to switch 120VAC. Or wire the contact in parallel to switch high current loads.


What's Included

  • 1x - High Sensitivity DPDT Relay Board
  • More Info

    Use this relay if you need a DPDT output or need it to work with a relatively small trigger current/voltage.

    JAROSLAW -- east hampton, CT   4/9/2012
    looks high quality, won't operate dirrectly with water sensor
    JAMES -- jupiter, FL   9/3/2011
    great price. Easy to hook up. Works well with optical isolator input from Flowlogic water alarm system.
    CHRISTOPHER -- greenville, SC   1/5/2011
    This product does exactly what it claims to do. Do note that it has two output relays, each double-throw, but only one input! I am using it with a modified Sylvania EcoLight shower light, item 46214, to detect water flow very inexpensively. The design of this product is simple enough that I could have easily built it myself, but I would have spent a little more in parts, so this is easier.
    MARK -- heber, UT   4/12/2010
    Seems to work as advertised.
    JOHN -- greeley, CO   4/11/2010
    I have not 'hooked up' the timer yet but you offered a product in my price range and I'm sure I'll source you in the future for other items.
    MURAD AHMED -- springfield gardens, NY   2/18/2009
    These are great relay board, just what i was looking for.

    I have no complaints
    MICHAEL -- spotsylvania, VA   4/25/2008
    Good quality, good documentation, cheap price, fast delivery - what could you ask for. You guys are great!
    EMLYN -- north richland hills, TX   3/10/2008
    It worked as expected. I would not depend on the double stick tape to secure it. The corner holes were too close to the printed curcuit. I had to use insulated washers when mounting it.
    BRADLEY -- menlo park, CA   2/6/2007
    Performed as described.
    MICHAEL -- lithia, FL   1/9/2006
    Looks to be good quality and perfect for special needs
    ROBERT -- silver city, NM   10/23/2005

    CRAIG -- cudjoe key, FL   9/16/2005
    good product
    WALTER -- washington, NC   1/30/2004
    Used relay to signal a break bell connected to time clock. Works perfectly.
    NIVEN A. -- hollywood, FL   8/19/2003
    High quality but there was a small problem with delivery the address got mixed up.
