ACPL-824-500E

Optoisolators are electronic components used to transfer electrical signals between two isolated circuits, providing interface isolation and electrical protection. More specifically, an optoisolator, also known as an optocoupler, opto-isolator, photocoupler or optical isolator, is an optoelectronic device that can be used to isolate the input of a system from its output. One of the most popular optoisolators in use today is the ACPL-824-500E.

Application Field:

The ACPL-824-500E is a popular optoisolator designed for use in a variety of applications, including industrial automation and control, communication and networking, consumer electronics, medical equipment, transportation control, and consumer appliances. The ACPL-824-500E is typically used in power supply isolation, protected signal transmission between a transmitter and a receiver, and parasitic control to reduce EMI. Additionally, the optoisolator provides an electrical isolation barrier in applications that require isolation, such as a battery charger or a power monitoring system.

Working Principle:

The ACPL-824-500E optoisolator works on the principle of light coupling. The device contains a light-emitting diode (LED) that emits a light in response to an electric current and a photosensitive detector that detects the light. The electric current passing through the LED activates its photovoltaic effect and produces light that is detected by the photosensitive detector. This causes the output of the detector element to generate an electric voltage, which is then amplified and used to control the output circuitry.

The ACPL-824-500E is designed to provide high performance in a wide range of applications. It is an efficient optoisolator that has low power consumption and low leakage current. The isolation barrier of the device prevents voltage spikes, high transient voltages, and electromagnetic interference from disrupting the operation of the system. Additionally, the optoisolator has a high degree of accuracy and repeatability, ensuring reliable data transmission and signal conversion over its entire range.
