Need to drive high current or high voltage devices with a low voltage or low current signal? This premium dual 10A relay breakout board can handle it!

This version of the board uses 5V relays and can be triggered with 3.3V or 5V logic signals – ideal for the Arduino, Raspberry Pi, and other microcontrollers/microcomputers.

The board uses high-quality North American sourced parts and logic that is a lot more friendly to common microcontrollers and single-board computers. Simply connect 5V power, Ground, and your digital I/O to the 4 pin header and that’s it – no need for any additional components! We offer a matching 4-pin Molex KK to male jumper cable for this relay module here!

Each relay has the Input, Normally Open, and Normally Closed contact broken out to a nice 5mm pitch screw terminal and each trace is separated by isolation routing. Indicator LEDs show the status of the relay coil, when lit the coil is active.

The breakout board is sized to fit directly in a Hammond 1591LFLBK Small Enclosure. Perfect for making a clean, enclosed control box (enclosure sold separately, please check our range of Hammond enclosures for availability)

Please Note: While this board is capable of switching higher voltages, please exercise caution.
