The PS2561AL2-1-V-A is a member of the optoisolators/transistor photovoltaic output family. It is an optoelectronic device that transfers electrical signals from one electrical circuit to another while keeping them electrically isolated. The PS2561AL2-1-V-A consists of a coupled infrared light emitting diode (LED) and a phototransistor. It allows complete electrical isolation of one circuit from the other.

Application Field

The PS2561AL2-1-V-A is used in many different applications, such as industrial automation, consumer electronics, computers, telecommunications, automotive, and many more. It is most often used in applications requiring electrical isolation such as signal transmission, data communication, and motor control.

In industrial automation, the optocoupler is used for isolating and detecting the status of a signal. It is used to reduce electrical noise and provide protection against electrical surges. In consumer electronics, it is used for isolating signals from various components in television sets and other electronic equipment. In computers, it is used for isolating logic signals on the motherboard and transferring them to the peripherals. In telecommunications, it is used for isolating the signals between the control station and the devices connected to it such as telephones and modems.

The optocoupler is also widely used in automotive applications such as airbag systems, engine control systems, and brake systems. It is used for isolating the signals between the control unit and the components of the systems.

Working Principle

The PS2561AL2-1-V-A consists of a photoemitter and a phototransistor. The photoemitter is a light emitting diode with a narrow frequency range. When the LED is energized, it emits a narrow band of light. This light activates the phototransistor which then turns on, allowing the signal to be transmitted to the other electrical circuit.

The optocoupler offers complete electrical isolation between the two circuits. It also provides protection against electrical surges and reduces any noise interference between the two circuits. The PS2561AL2-1-V-A is designed for low-frequency signal transmission up to 10 MHz.

The PS2561AL2-1-V-A is an ideal choice for applications requiring high speed yet reliable electrical isolation. It is available in a wide variety of packages and is well-suited for operation in hostile environments.
