Replacement:KIT-11042. The new board is routed to provide more isolation for the high voltage traces. This page is for reference only.
Your 5 volt system can wield great power with this big beefy relay board. How does 20 amps at 220VAC sound? The Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control.
The heart of the board is a sealed, SPST-NO 20A Relay. The relay is controlled by 5V logic through a transistor and an LED tells you when the relay is closed. This is a kit, so it comes as through-hole parts with assembly required which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.
Note: There are unfortunate flaws with this design. If you have this board, we recommend not using it unless you are fully aware of its limitations and problems. There is a small risk that in certain situations this board could become electrically compromised. If this were to happen, the isolation of voltage may become unreliable. To avoid issues, we recommend that you do not use metal hardware to mount this board. Also we recommend that you do not over tighten any hardware to avoid any unneeded damage. If you would like to return the device for a refund, we would be happy to help you out. We can supply a return label, and a refund, just contact Tech Support, or Customer Service with your order number for assistance with a return.
