Optoelectronic Isolation
2018-11-07

Optoelectronic Isolation is a method to isolate the input and output signals physically and electrically by using light as a signal medium to minimize interference between the two signals. Solid state relays use opto-coupler as signal isolation method, so its EMC (the ability to control EMI) is better than mechanical relays.
