The ACPL-1770L-200 is an optoisolator which has a transistor and photovoltaic output. It is an integrated and cost-effective device which provides superior performance for signal isolation applications. An optoisolator is an electrical component which helps to electrically isolate two circuits that are connected to each other. The ACPL-1770L-200 offers enhanced safety and reliability for industrial, consumer, medical, military, automotive, and telecom applications.

Working Principle

The ACPL-1770L-200 optoisolator operates under the principle of producing and detecting light in order to establish a physical barrier between two different signals. The optoisolator has an LED emitter which is connected to the input circuit, and a photovoltaic detector which is connected to the output circuit. When the input signal is applied, the LED emitter will produce a light signal. This light will then be detected by the photovoltaic detector, which will then generate the corresponding output signal to the second circuit. The light signal is immune to any electrical noise or interference, providing secure electrical isolation.

Application Field

The ACPL-1770L-200 is commonly used in industrial control, data acquisition, and communications applications. It is also used for closed loop architectures and other reliability-critical applications, such as medical equipment, military systems, and telecommunications systems. It is also used in consumer products, automotive applications, and power supplies. Its superior breakdown voltage (3kV) and superior common-mode noise rejection (20dB) make it suitable for a wide range of applications.

The ACPL-1770L-200 is also typically used for safety isolation of low voltage signals in both industrial and medical applications. It provides, reinforced insulation between circuits, ensuring that signals between devices are properly isolated from disturbances due to electrical noise or high voltages.

In summary, the ACPL-1770L-200 optoisolator is an integrated, cost-effective, and reliable device that is suitable for a wide variety of signal isolation applications such as industrial control, data acquisition, closed loop architectures, and medical equipment. Its superior breakdown voltage and common-mode noise rejection make it ideal for applications where reliability is essential.
