Optoisolators with transistor and photovoltaic output configurations are devices that provide electrical isolation and signal transfer between input and output circuits. They use an LED optically coupled to a photodetector, typically a phototransistor or a photovoltaic cell, allowing them to transmit digital or analog signals across isolation barriers in applications like signal isolation, digital logic interface, and feedback control systems.
