Opto isolated relay module

WebAug 17, 2024 · The optoisolator does not isolate by default, but if you remove the jumper, it allows you to use isolated supplies on MCU and relay side of the optocoupler. In theory you could have two separate supplies, one 5V supply for the MCU side and another 5V supply for the relay, and have 5000 volts difference between those two supplies. WebOct 11, 2024 · Active Low relay boards are preferable in most electronic projects. These work by adding a Optical Isolator and a MOSFET between the relay and the Controller. The MOSFET wont be drawing current until you pull that line low. neither will the OPTO Isolator.
