PS2561AL2-1-H-A

Optoisolators - Transistor, Photovoltaic Output, such as PS2561AL2-1-H-A, are often used to protect the circuits from high voltages, prevent damages caused by sudden power failure, and create electrical isolation between two circuits as well. This article provides an overview of the features, applications and working principle of PS2561AL2-1-H-A.

PS2561AL2-1-H-A is a type of optoisolator module, which consists of a light-emitting diode and a phototransistor integrated into a single package. It offers an isolation voltage between input and output up to 7.5KVrms, which means it is capable of isolating two circuits that operate at high power. It also has a maximum blocking voltage of 37V and a maximum forward current of 100mA. Because of its low power dissipation and small size, the PS2561AL2-1-H-A is suitable for a range of applications where a high isolation voltage is required in a small footprint.

One common application of the PS2561AL2-1-H-A is the protection of the digital logic circuits from high voltages or power fluctuations. It is often used to isolate the low-voltage logic circuit from the high-voltage power circuit. It can also be used in motor or transformer control, where it serves as a sensitive interface between logic circuits and motor or transformer. In addition, it can be used for data transmission and communication between two circuits, providing electrical isolation to ensure that signals are not corrupted by external noise.

The PS2561AL2-1-H-A employs a light-emitting diode (LED) and a phototransistor to provide electrical isolation between the input circuit and the output circuit. When an input signal is applied to the LED, it will emit light, which will be received by the phototransistor at the other side of the module. The phototransistor will then amplify the light signal, which will be transmitted to the output circuit and actuated according to the input signal. The light signal is completely isolated from the input and output circuits, which provides the required electrical insulation.

The PS2561AL2-1-H-A is an ideal choice for applications requiring a high isolation voltage and small footprint. It offers excellent performance, reliability, and cost-effectiveness, which make it suitable for a wide range of applications. It is a proven technology that is used in many industrial, automotive, medical and aerospace applications.
