Optoisolators, also known as optocouplers, are devices that are used to electrically isolate two parts of a circuit. ACPL-827-50CE optoisolator is a type of optoisolators that is widely used in various applications due to its high performance and reliability. This article provides an overview of the ACPL-827-50CE application field and working principle.

Field of Application

The ACPL-827-50CE optoisolator is a 3-channel, 4-pin, transistor output optoisolator. It is suitable for a wide range of applications including automotive, industrial, communication, computing and consumer electronics. It is also widely used in medical, aerospace and defense applications. The optoisolator features a high isolation voltage of 5 kV and a high operating temperature of 85°C. Furthermore, it has a wide operating temperature range of -40°C to 85°C.

The optoisolator is designed to provide electrical isolation between two circuits while allowing digital signaling. It enables signals to pass between two electrically isolated circuits without directly connecting them. It is commonly used in motor control applications, where it can effectively isolate sensitive circuitry from low-voltage control systems. Additionally, it can be used to isolate control signals from high-voltage circuits, and to protect circuits from ground loops.

Working Principle

The ACPL-827-50CE optoisolator consists of an infrared light-emitting diode (LED) and a photovoltaic (PV) detector. The LED emits infrared light when it is turned on, and the photovoltaic detector converts this light to electrical energy. The photovoltaic detector is connected to a transistor, allowing it to transmit electrical signals. When the LED is turned on, a current is passed from the photovoltaic detector to the transistor, which in turn drives the attached load.

The optoisolator provides a high degree of electrical and optical isolation between two circuits. It can be used to prevent electrical interference and noise from one circuit affecting another circuit. Additionally, it can be used to protect sensitive circuits from damage due to surges in voltage or current. The optoisolator’s wide operating temperature range and high isolation voltage make it suitable for a variety of applications.

In summary, the ACPL-827-50CE optoisolator is a high-performance, reliable device that is widely used in various applications. It features a high isolation voltage and a wide operating temperature range. The optoisolator consists of an LED and a PV detector, which allow it to provide a high degree of electrical and optical isolation between two circuits. It is commonly used in motor control applications, and to protect circuits from ground loops and voltage surges.
