About Transistor, Photovoltaic Output Optoisolators
Transistor or photovoltaic output optoisolators are electronic components designed to transmit information across an electrical insulation barrier. They are commonly employed for safety or functional purposes, particularly in situations where it is necessary to isolate and protect sensitive components from potentially harmful electrical signals. What sets transistor or photovoltaic output optoisolators apart from other types of optoisolators is their utilization of a simple phototransistor or photovoltaic cell (also known as a solar cell) as the output device. These devices convert light into electrical signals without the need for an external power source. Unlike logic output optoisolators, which provide digital output signals, transistor or photovoltaic output optoisolators produce analog output signals. This analog nature allows for the transmission of continuous, non-digital information between circuits that cannot be directly electrically connected, such as those operating at different voltage levels or with incompatible signal formats. The phototransistor or photovoltaic cell in these optoisolators acts as a light-sensitive device, converting the received light into an electrical current or voltage. This output can then be used to convey analog information between the input and output sides of the optoisolator, enabling communication between isolated circuits. In summary, transistor or photovoltaic output optoisolators utilize light to transmit information across an electrical insulation barrier. They differ from other types of optoisolators by employing a phototransistor or photovoltaic cell as the output device. These optoisolators do not require an external power source and generate analog output signals, facilitating the transmission of analog information between electrically isolated circuits.
