Optoisolators are a type of electrical component used to isolate two circuits electrically while allowing signals to be transferred between them optically. They are popular because they provide "noise" or electromagnetic interference (EMI) immunity in demanding applications. The CNY17F-4S(TB) is an optoisolator that specifically isolates one circuit from another using a combination of a transistor and photovoltaic output. In this article, we will discuss the CNY17F-4S(TB)\'s application field and working principle.

Application Field

The CNY17F-4S(TB) can be used in a variety of communication applications including RS-232, CANbus, and RS422. It is ideal for use in industrial production lines, communications, and robotics as it isolates the sending and receiving devices, and works at baud rates from 300 to 1,200 baud. As a result, the CNY17F-4S(TB) is ideal for industrial environments where noise sources and ground loops may be present.

Working Principle

The CNY17F-4S(TB) works by providing an optical barrier between two circuits. It utilizes a transistor (NPN) output and a photovoltaic element, allowing signals to be sent and received between two separate isolated circuits. The optical barrier is created by the photovoltaic element which converts light signals from one circuit into electric signals, which can then be used in the other circuit. The transistor output provides a higher current and can be used to control multiple remote devices.

The CNY17F-4S(TB) also includes an LED indicator which displays when isolation is present between the two circuits. This LED indicator is placed on the receiving circuit and will light up when signals are sent from the transmitting circuit, indicating that an optical path is present between the two circuits.

The CNY17F-4S(TB) is a reliable and efficient optoisolator which works by isolating one circuit from the other using a combination of a transistor and photovoltaic output. It is ideal for industrial environments where noise sources, ground loops, and other electromagnetic interference may be present, as it provides an effective shield against any interference. By isolating two separate circuits, the CNY17F-4S(TB) is able to send and receive signals reliably, without any fear of disruption.
