Opto-isolation is a great way to protect sensitive circuits or ensure physical separation. These optoisolated Relay Breakout Boards are very similar to our standard 2 Channel Relay Breakout Boards, with one key difference: it completely isolate your relay circuit from your control circuit by means of an optoisolator. These are a must when sensitive electronics are used or where the operation of the logic side is critical to other systems.
This version of the board uses 12V relays and can be triggered with logic signals from 3.3V to 24VDC – ideal for automotive, marine, and other systems that have 12VDC power available. The board uses high-quality North American sourced parts and features a boatload of isolation routing. 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.
Please Note: While this board is capable of switching higher voltages, please exercise caution. If you are inexperienced or unsure about how to use this product safely, please contact a professional.
