Overall, the CNY17-4S-TA1 provides isolation and can be used in any application where electrical signals need to be safely and securely transmitted.

Working Principle

The CNY17-4S-TA1 is a Transistor, Photovoltaic Output optoisolator. This means it uses a phototransistor to isolate the electrical signals from one another. The phototransistor is made up of three parts: the collector, the emitter, and the base. The collector and the emitter are separated by an insulator, allowing them to be electrically isolated.

When light is shone onto the base, it creates an electrical current known as a photovoltage. This photovoltage causes the base to turn on, which, in turn, turns on the collector. The collector is connected to the emitter, which is connected to an output. When the base is on, the collector is also on, and the emitter is able to transmit the electrical signal from the input to the output.

The CNY17-4S-TA1 is an optoisolator designed to provide electrical isolation while allowing signals to be transmitted from one device to another. Using a phototransistor, it is able to safely and securely transmit electrical signals from one place to another without the risk of interference.
